Starling's New 170mm 29er With a Gearbox - Bespoked Show 2019

May 3, 2019 at 11:52
by James Smurthwaite  

Another week, another Starling with an intriguing drivetrain system. This time, Joe McEwan has built up a new bike for a long term customer with an Effigear gearbox. Named after the talon on the back on a starling's leg, meet the Spur.

The blueprint of the Murmur is writ large on this frame despite the addition of the gearbox.


Effigear are a French company and Joe has fitted this new Spur with their 9 speed box. The box mates with the swingarm in a manner that means there's no chain growth. This, combined with a lack of derailleur and cassette on the rear wheel, apparently make for a super supple rear end. Another big advantage of the Effigear is that it can be fitted with a trigger shifter, unlike the Pinion which is gripshift only.

Joe fits one of these plates to every ride and they look stunning.

The Spur has the option to change the shock position, a first for Joe.

Joe has fitted the gearbox with a brute of a bike; like a Murmur on steroids, this is a 170mm 29er. The customer Joe made this for is a sizable gent so this bike has a reach of 520mm and 450mm stays. Basically, when the Spur gets trucking, it's going to take a lot of stopping.

The cable routing for a stealth dropper was supposed to go through the stainless steel plaque on the downtube, but wasn't needed thanks to the Magura Vyron spec. It's something Joe is working on for all future Starling bikes.

A singlespeed hub from Project 321 is all that's needed on the rear wheel.

Joe currently isn't planning on building anymore of these bikes but he has all the jigs and could make one up if a customer really wanted. Expect a frameset to cost around £2,000 if you're interested.

Trigger shifting is a big plus on the Effigear. Joe's Spur runs with a Sram GX shifter.
A custom headcap finishes off the build. #steelisreal is a community of British bike builders that hold an annual demo day for their ferrous bikes.

 I have a Pinion gearbox and it's handsdown the best piece of kit I've ever had on a bike. I've always been interested in the Effigear box too, except that the bike company who makes them; Cavalerie's bikes are ridiculously expensive for something that looks like someone threw together in a shed out of scrap alloy.

Always thought the Effigear gearbox was cool though, especially because they have trigger shift, but honestly after 10 minutes on a Pinion with a grip shift, I prefer it much more to trigger shifters now.

 @audric: What other gearboxes have you ridden? How do they compare?
  • + 4
 @excavator666: i rode the effigear gearbox for 8seasons, and did a ride on the Pinion in Whistler.
I'd say that the effigear has a smoother functionning, and the shifter is also WAY better than this satanic gripshift.
Overall gearbox bikes are (to me) more balanced as the weight is centered on the bottom bracket and corner like Hell. Not mentioning that having no chain slapping your swing arm while giving'er is quite addicting...
i'm back with an old fashioned deraileur on my new trek slash, and miss the gearbox comfort shifting up or down and having the right gear instantly (without pedaling)
I hope i answered your question!
  • + 2
 @audric: That's great, thanks for your insight dude! I've been obsessing over gearboxes ever since I seen a Diamondback Sabbath back in about 2008. I knew then that this what I wanted.

I've spec'd up Cavaleries many times on their website, but always thought that their bikes were ridiculously expensive for what they are.

I now own a Zerode Taniwha and I can honestly say that it's EXACTLY the bike I've been waiting for since 2008.

I thought I wouldn't like the grip shifter, and it delayed me from making the purchase for a long time, but now I think it's a far superior system to trigger shifters. I love being able to dump or grab as many gears as I want, whenever I want (except whilst putting down a lot of power, which just requires an adjustment to the shifting technique).

The quality of the grip shifter is brilliant. It's a far cry from the awful plasticy things that used to come on bikes in the 90's/2000's. The feel of the shifter is beautifully mechanical and precise.

Whenever I'm washing the bike after another trouble free ride I think to myself "Ah remember when we used to have those ridiculous fragile pieces of scrap metal derailleurs hanging of the back of our bikes?.. Oh wait, most people still do!" and I laugh to myself and then rinse and dry my bike and put it away in anticipation of giving'er more trouble free abuse.

I also like the silent running part, or at least I would except that I have Hope hubs! They're great hubs, but the rear one is stupidly noisy, and honestly without the rest of the clanking and banging that normally comes from a bike, the whizz just sounds like a hiss, and it's distracting because it regularly makes me think that I have a puncture.

Noisy hubs are so last decade.

 Flimsy derailleurs and giant saucers aren’t going anywhere. I can bet any money that in 2022 Sram will have 13 if not 14 speeds. The last steps on Eagle are rather big, they will want to smoothen in out - guaranteed. I personally don’t use 50cog. Cannot imagine how someone can ride so slow and still consider it worthwhile to press on the pedals.

Then MTB is about weight, lower weight always sells better. Gearboxes will never be light.

Finally the poliferation of gearbox can only happen with sexy mainstream bikes using them, like Taniwha. I understand how steampunk things like this Starling are great designs and the build quality is excellent but they will never win hearts of the general public. It is the general public that pushes things forward in the end, slowly but it does. You can’t impose much on them.

So well, as you can see there are limitations to what genuine intellect can do.

 @WAKIdesigns: if you have a big enough chainring on your bike your bike will move with the 50t

I have a 34t chainring with a gx eagle cassette, and i likr it. I dont use it every ride but especially when i race i like to ride a higher cadence.

That being said . I cant notice that much of a difference from the 46 that i had, and only moved up to the 50 because it was the same price buying a gx groupset than buying a 11s with a 46t and xd driver that was what i had.

 @AGR97: if you come to Gothenburg I can serve you a few sets of climbs totaling at no more than 1000ft that will fist you in a matter of an hour, and you’ll miss smooth fireroad totalling at 4000ft. You just won’t make half of them if you shift to 50 simce you will either spin out or loop out. Using 50t, especially with anything smaller than 36t front is not synonymous with having tough climbs and being a bad ass. It is ridiculous to imply it. On the contrary I’d say. 10 years ago Alpine fire roads were dominated by folks riding up at snail pace, juggling their balls off while spinning 100RPM on their tripple chainsets.

 I'm a big fan of gearboxes and steel but am I only one who sees Starling bikes much overhyped. Details are amateurish, brazing is not clean (compare it to Curtis few posts down for example), important struts and gussets are missing, degressive shock curve with coil shock... For garage project it would be incredibly cool but for 2000 pounds?
  • + 32
 ''Important struts and gussets are missing'' . . . So what you are saying is you have an opinion based on looking only and a preconceived idea of what is needed, whereas Joe has a career in structural analysis, R&D and wing design in the aerospace industry.

 Maybe for chain tension as it gets a little longer overtime, or so you can change the cogs for different ratio ?
  • + 6
 No sliding drop outs, that's why. Try getting the exact right length chain between the sprockets, then try actually getting it on. An idler pulley is standard engineering practice for chain drive (and belt drive systems) that don't have a means to tighten the chain or belt by extending the drive and driven sprockets apart. Your non gearbox bike has an idler. Your timing belt in your car has an idler. Your Wahoo Kickr has an idler. It has nothing to do with chain stretch, but that is compensated for as a bonus side effect.
  • + 0
 @handynzl: yeah i get that hence my post, again, why not use a a chain tension system of some sort, bmx and dj bikes don't use a poxy tension system.
  • + 1
 @watchtower: BMX and DJ have sliding drop outs so you can push the wheel back and tighten the chain. That idler on this bike is sprung to give tension. It won't be rigid.
  • + 1
 @handynzl: the "tensioner" appears to be void of a spring. If the suspension pivot is at the front sprocket centre , which it appears it is then it would work a treat with bmx or dj sliding drop outs.

 People there are some mechanical secret tricks that make the bike actually capable to jump and go faster, for example the bolt tightening sequence, try this:
-Tighten handlebar and stem bolts top to bottom, ride it, and then tighten them bottom to top. you will feel it gives you a different handling, also if you tighten them left to right or right to left.
