MULLET

PRESS RELEASE: Cotic

Haircut time! We've tested and experimented enough to be happy to offer Mullet options on all our droplink frames. By utilising a Works Components 1º angleset, you can now put that party in the back and run a 27.5 wheel.

Jeht Mullet

When you fit a smaller rear wheel wheel to a 29er bike, the BB drops about 10mm, and the head angle slackens nearly 1 deg. By installing the angleset to steepen the head angle again, this also acts to lift the BB up too.

RocketMAX Mullet

Brand ambassadors and bike riding wizards Chay Granby and Wayne Coates both did extensive testing on the RocketMAX:

"...for some riders, just to have that smaller back wheel to give more room on the very steep stuff, whilst still having the improved rollover on the front felt great.

The end result was I loved it. It's certainly still fast and just lets you be that bit more nimble when required." - Chay.

"I feel I can move the bike around a lot easier, muscle it and drift in to corners with more ease and predictability. I couldn’t tell you if its a faster set up but I’m puzzling less and that means I’m having more fun." - Wayne.

Geo tables are for the Jeht, our 150/140 do 'owt bike, but all the droplink frames can be 'mulleted' and the charts are on the website

However, if you think it's a bit of you straight away and you want to reserve yours, click on the button and make an order. We have frames & Deore groupsets in stock right now; depending on spec we could be able to delivery before Christmas.

 @MattP76: I agree with you it's like the industry has peaked on actual useful tech now they just slap a couple different wheel sizes on one bike and that's the innovation for this year lol meanwhile it's just reusing what's already been done.
  • 1 0
 @mhoshal: Thank you. I am all for innovation and progression.... Big time!!

If it's one sport that needs some radical innovation it's Mountain Biking. It's be regurgitating the same sh*t for decades in some cases. This utterly ridiculous fad of having odd size wheels as progression is just the biggest joke I've seen in the 25+ years I've had in this sport. Just because your favourite downhill racer pretends to love it doesn't mean it's amazing.

Bring out some proper innovation and I'll be the first person hugely applauding it. Don't pass off utter fads as the next best thing.

 @MattP76: I'm pretty much a midget, with the shortest legs on a bicycle, mullets make all the sense for me and people like me.
I have zero chance of getting my hips over the rear axle with 29" and huge chainstays, a smaller rear wheel helps.
This is why I'm riding on small wheels currently, despite 29" being faster, I would sacrifice too much control in really steep stuff and a lot of fun by going to wagon wheels.
With a mullet, I get that nice little boost in roll over, and reduce the chance of getting catapulted over the front in really rocky stuff.

 @Losvar: Ride a 27.5 then! Why oh why people think they are impossible to ride these days is staggering. You don't need a Mullet! No one does.
  • 1 0
 @MattP76: if a muttet fits you better then a 29er imagine how good a full 27.5 would be for you. I'm a guy that likes to wear my rear tire then buy a new front tread and rotate the old front to the rear. I wouldn't be able to do that with mullet which is why I'm staying away from them. Plus I like having multiple rims sitting around in case I taco one. I don't need two sizes sitting around when I could just use the same size rim for the front or the rear. Mullets in my opinion are just more of a headache.

 Shouldn't the seat tube be more like 1.5 degrees slacker?

It gets about 1 degree slacker due to the smaller rear wheel, then when you raise the front end via steepening the head angle, it should get slacker again.

I don't follow the math...
  • 3 1
 2.5deg slacker on the small I think. The geo chart is wrong
  • 1 0
 Exactly!

Also, can the wheelbase really be 10mm shorter??
  • 3 0
 @Timo82: Yeah wheelbase could end up shorter due to the angle set. They've tipped the whole frame backwards and then pulled the front wheel back in.
Mainly the seat tube angle that doesn't add up to me.

Despite being dubious about the claimed relative change in seat tube angle, I thought it was interesting to reference the BB drop relative ro the 29er (front) axle. I always tend to think about it relative to the rear axle, but referencing to the 29er gives a more direct comparison to in terms of the relative change in BB height. That was a good call.
  • 3 2
 @hughlunnon: Geo chart isn't wrong. It's all taken directly off my CAD.
  • 2 0
 @Timo82: Yes. The steeper angleset shortens the front centre, and there is also a slight foreshortening effect due to the lower rear end.
  • 3 0
 @cotic-bikes: can you humor me and and explain how the seat tube ends up only 0.5 degrees slacker?

1. Smaller rear wheel slackens it by around 1 degree.

2. Raising the front end and BB by steepening the head angle should slacken it further.

The sum of these should be more like 1.5 degrees slacker, give or take depending on frame size.
What are we missing?

 @cotic-bikes: Not doubting your cad numbers but I’ve done this on a few bikes and found one or 2 off sett bushings will pick the back end up the last bit. Also running a little less sag (25%?) will bring the dynamic angles back and add the all important ‘pop’ folks are after with this setup. Thanks, you’re welcome.

 @PB-J: We initially did try modifications using offsets, but we didn't find them reliable enough. They have a tendancy to rotate eventually under load making the geometry worse, not better.

Hey guys/gals at Cotic bikes, if it hasn’t been said already, a huge shout out to you guys for doing the leg work, and letting everyone know you’re cool with this.
It can’t be overstated enough how cool it is that you’re giving a big thumbs up to what is essentially swapping a headset, so people can feel confident in trying out what seems to be very on trend.
Much respect. I’ve been looking at your bikes much more recently, and this type of thing makes me want to support your company.
Any Western Canadian dealers?
  • 4 0
 Thanks for the kind words. We really appreciate it. We don't sell through dealers. We sell direct to the world from our base in the UK. Just select your order on the website, and select Canada in the country chooser at the bottom of the page. All the pricing updates for shipping and taxes at that point. Easy.
  • 7 1
 That’s a great idea that should work with any bike. I highly recommend a full 27.5, though, they are lots of fun. A 29er certainly goes places easier but my 27.5 5010 puts the bigger smile.
  • 3 0
 good luck with IS headtubes..
  • 14 11
 Was quite excited by this, but alas its just the conversion like you can make with any frame.

The problem with just shuvving in a 27.5 wheel for me, is not the lower BB (steep rooty woodland here, this isn’t rocky utah) its the seat angle also slackens, compromising the pedaling position.
  • 32 2
 Sorry for the confusion. The slacker head angle comment related to just boshing a 27 5 rear wheel in. With angleset in to steepen the head tube angle back to where it was and lift the bb, it only slackens the seat angle by half a degree. Push the saddle forward 5mm and you'll be pretty much back where you started. It's not perfect, but it's a really good option for people keen on the smaller rear wheel.
  • 3 0
 I agree. I'll go with Cotic's reply but the point is their sa's are already pretty slack. I think I wouldn't matter that much if the sa is around 77° / 78°. Then you would have a nice steep sa for the 29'er and a little less steep sa for the mx version. Assuming the latter will be ridden more in bike parks / jump trails.
  • 3 2
 @dennis72: then just turn the Anglesey around and slacken it out again which would help steepen the seat angle. And then run shorter cranks.
  • 2 0
 @cotic-bikes: Hey maybe I'm not steezy enough on my bike to understand, but why aren't reverse mullets a thing? I notice the 29 vs 27.5 size/weight difference most in my front wheel. This is where the larger 29 seems to be more resistant to change of direction vs the 27. Just curious.
  • 4 0
 @cotic-bikes: I've gone the opposite direction with using anglesets to slacken the front end and steepen the effective SA. Yeah, the BB is low like this, but it is not an issue if you swap to 165 cranks. I did this with a V1 Wreckoning and it turned an already ripping frame into a monster without any downsides. A Works Components angelset is the least expensive yet most drastic way to alter the character of a bike. Lastly, a mullet or MX set up is a huge plus for me at 170 cm giving the bike a more playful vibe without the dread of taint buzz on the steeps.
  • 4 0
 @hellbelly: If a slackset has improved your bike then that's great. For us that would have dropped the BB over 10mm which would have been too low for all but the smoothest trails. We live somewhere with nobbly, techy, rocky climbs and it is good to be able to keep pedalling up them without catching your pedals.
  • 2 0
 @Moonie2123: Never tried it, but the difference in rollover performance of the bigger front wheel is a big plus, and having the axis of the bike tipped back (the lower rear axle makes the axis of turning not parallel with the floor anymore) seems to make initiating turns easier. Going the other way would make it worse.
  • 1 0
 @cotic-bikes: I've not ridden nor visited the UK, but my oldest is considering studying abroad there after having fun spring break trip there last year. Obviously I'd have to visit and sneak in some rides. There are plenty of roots, rocks and general janky trails not to mention the ton of rain where I live in N Georgia USA and if the stuff around here isn't gnarly enough I can always drive up to Pisgah which I do a few times a year. The bottom bracket height of that bike I put the angleset on ended up at around 331mm. My current whip is slightly higher. Again, with my short legs I love the way the bike handles and the cornering is unreal. I have to be mindful of pedal position, but it's never been a deal breaker.

 @hellbelly: RocketMAX BB is 348 static, but because our frame rate is progressive and we run 30% sag on the shock, the dyanmic BB height is a little under 280mm, which is pretty low already. I've certainly tried lower and with 170mm cranks there's no chance of getting up a lot of our local trails. Very bike dependent, but also how much you're willing to put up with one end of the compromise for improving another.

 @cotic-bikes: Yeah gotcha, wasn't considering the difference in axle height, just overall geometry. I've got a 27.5 with 160mm fork I could swap on to the front of a 130mm travel 29 setup. Could be interesting...
  • 2 0
 I'm running a 2018 commy meta am 29 as a mullet, and have found my results in line with what cotic mentioned, an about 1 degree slacker STA is pretty use-able if you just push the seat up a bit. Honestly, and this is a hot take, but my bike is climbing essentially just as well as it was before. It takes on tech worse bc of the BB height but for punchy rollable climbs the smaller wheel feels torquier.

 Seat angle changes by only 0.5 degrees even though the BB drops by 10mm and the front is then lifted enough to bring the BB back up? So, the equivalent of at least 20mm lift in the front, if the wheels stayed the same, and that's only changing both actual and effective seat angles by half a degree? I've seen other bikes claim a half degree angle change from mere 6mm of BB drop/rise. What's happening here?
  • 2 1
 It's not that big a "lift" at the front. These days there's only about 15mm difference in radius between 29 and 27.5, and the headset only lifts the front a little more. I know it sounds counter-inutitive, but these numbers are straight off my CAD, and to be honest until I first did the layouts I was skepical too. The numbers are the numbers though, and everyone who rode a test bike had no trouble adapting to the changes.

It was worth every. penny and I'm now eyeing building up a Cotic for my wife.

 good to put out there these things to make people think a little bit.. yes, it's not rocket science.. good luck to all of you brands making IS headtubes when getting this question asked... I wont have a bike that has IS, ever... that is why I got a Spire... that I will make mullet , and may be drop the +1 angleset in the huge headtube it has.. by the way, if the COTIC had a better cable routing I would have gotten one.. I just cannot stand that cable hanging around the rear shock.. but to each their own....nice bikes.. cheers guys

 Is it me or the mullet things does not really appeal to me? I've ridden recently a Commencal meta HT with both mullet (27+/29) and full 29 on my hometrail. The mullet was quite dull compared to the full 29 and really less efficient when pedaling. I can imagine the mullet fun factor in bikeparks or during tough enduro races but for common trail riding, the full 29 is still the best compromise (IMO).
  • 4 0
 It's very much a preference thing. As you can see from the quotes above, some riders prefer the feel and get something out of it. Me (Cy), I like full 29. It's an option.
  • 2 0
 If Cotic have done the maths, I would think Works might be selling a few more anti-slacksets in the next few weeks.

Would a small frame not be affected more than a larger/longer frame though? The change is further away from the pivot point (the rear hub axle) as you go up the sizes, so the changes would be ever so slightly different for each frame size. Wouldn't they? Probably too small to bother worrying about...
  • 3 0
 Very slightly more on smaller frames, but not enough to be concerned about. We tested on a small FlareMAX, medium and large RocketMAX and medium Jeht so we are happy that it works across all sizes and models.

 rockin a 27.5/26 myself now with 160mm cranks and thinner pedals. what a treat! I can finally take the pie plate cassette off and use a smaller one….smaller rear wheel = lower gears.. (caution, not recommended for trend following riders)
  • 4 3
 Well, I guess this is as good a time to ask as any...

Why is it called a mullet?

As a hairstyle, a mullet is short in the front and longer in the back. So why is a bike with a smaller (corresponding to shorter) wheel in the back called a mullet?!
  • 18 3
 Really a reverse mullet, but one word is sufficient now.

Plus, business up front is 29- no nonsense, get outta my way.

Party out back is 27.5- drifty, nimble, more clearance & capable

 @Staktup: I will die on the hill that "reverse mullet" is the dumbest thing ever. Its BUSINESS in the front and PARTY in the rear.

29ers are the business CEO's of the bike world. Winning races and crushing trail. 27.5 wheels smoke cigs and drink Busch heavy before and during their ride.

  • 3 2
 @cotic-bikes I don't believe the seat angle is correct here. You've dropped the rear of the frame by 19mm and raised the front by 8mm (according to the stack). reach + chainstay on a small is 884mm. I make that you've rotated the entire bike backwards by ~2.5 deg, which should have the exact same effect on the seat angle.
  • 3 2
 It's not as extreme as that. You're conflating measurements that are a result of the global changes and aren't measured around a fixed datum, because the whole axis of the bike has changed. It's all measured off the CAD. First thing would be that the difference in tyre radius isn't 19mm as 27.5 and 29 aren't exactly proportional to their rim ISO measurements once tyres are involved. Also, the angle is based around wheelbase, not rear centre plus reach.
  • 2 2
 @cotic-bikes: I think my calculations were off, but I think yours are too. You are claiming that the fork angle changes by 0.1deg, which means the height of the front of the frame moves by less than 1mm (assuming the cup depths on both headsets are approximatly the same?)

you're then showing that the stack is consistently 8mm more on the mullet bikes. With a fixed front end height, this can only be due to the bottom bracket being lower, by 8mm (not the 4mm in your spec). This would then translate to a 16mm lower rear axel, which would roughtly equate to your statement of 'not quite as much as iso' (of 19mm).

if the rear of the bike is 16mm lower and the front of the bike is the same height, over an 884mm frame (wheelbase doesn't matter as stack is measured from the headset, not the front wheel), the whole frame is rotated rearwards by 1.04 degrees (which again aligns with using a 1deg 'slackset' to get the head angle almost the same again).

so apologies for my maths being incorrect, but my suspicion is your cad model is still wrong. if the drop is correct due to a taller lower headset cup, then you've rotated the frame back by about 1.3deg.
  • 3 1
 @hughlunnon: The angleset has an external top cup. The regular headset is zero stack. The stack measurements are taking account of this because the bars will always be higher on the mullet due to the headset.

 I'm confused, it states above "the head angle slackens nearly 1 deg" but when you look at the geo chart it shows it's 0.1 deg steeper, is this a typo? Either way, really lovely bikes - really enjoyed my time on a flaremax
  • 7 0
 The mullet geometry figures are after they've added a +1 deg headset.

 @chakaping: ...fitted backwards... -1... so the headtube angle steepens back up by approx 1 deg to get it back to where it is for full 29er.

 They fit an angleset, which sets head angle back to (almost) the same as 29, and lifts the BB up a bit
  • 3 0
 @Spittingcat: +1 means it adds one degree to the head angle, rather than the much more-commonly used -1 or -2 headsets.
  • 2 0
 Glad you're enjoying your FlareMAX. Geo chart is corrected with the angleset installed to steepen the head angle again. The "slackens" comment relates to just boshing a 27.5 rear wheel in the bike without making any other changes.

 Zee cage is a winner for that top tube bottle position. I’ve never lost a bottle. When going back to my hardtail, I’m always surprised how stupidly low down the bottle is mounted when grabbing a drink riding off road.
  • 1 0
 My BFeMax comes with four different bottle mounting positions. I did under the top tube for a while and found that my Fabric cage caused road rash like scrapes on my knees on the days I chose not to wear pads. I'd suggest using the mounting spot for a bag or the like or ensuring the cage doesn't have textured sections like the Fabric cages. But I never had a bottle fall out of that position if that's help.
  • 1 0
 @soaklord: The bottle position on the droplink bikes is much further forward than the top tube position on the BFeMAX. Although you're obviously welcome to put a bottle there, that was more intended for tool mounts and the like. If you like on bike storage, we do custom bags for under the shock and at the head tube for all the droplink bikes, and they work great on the hardtails too.
