Cotic Announces Droplink Mullet
COTIC
DROPLINK
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.
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.
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.
There is a lot more info on this new option over on our website, so stick the kettle on, click the link and have a read.
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.

For real real on that rear wheel wheel.
Def Leopard sucks!
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.
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.
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...
Also, can the wheelbase really be 10mm shorter??
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.
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?
The angleset bringing it all back in
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?
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.
Agree, no problem with a ghetto conversion for something with 78 degrees, but the seat angles too slack for my long legs as it is.
Plenty of options out there so why compromise?
Lol, you know that was an april fools, yea?
Although the twist is an amazing, proper mullet

Ha ha! Brilliant. I have a few ciders with Joe, he’s a top lad!
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...
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?!
Plus, business up front is 29- no nonsense, get outta my way.
Party out back is 27.5- drifty, nimble, more clearance & capable
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.
Get it right people.
This guys knows the score.
Therefore they should in fact be called Karen bikes!
And people who have them should be ashamed of themselves for furthering the Karen-ist agenda.
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.
