Nov 30, 2023
by Gates Carbon Drive UT  


Kicking off our Driven series where we profile innovators in the cycling industry, we invite you to meet the team behind Gamux, who have made a huge impression on the World Cup downhill scene. From crafting their eye-catching CNC machined frames to expanding their Swiss distributorship, Gamux is truly sending it into the bicycle industry. In this video, we learn about their beginnings, their frame development process, their challenges, and their plans to keep Gamux at the forefront. Our entire Gates team is proud to work alongside Gamux, and that our Carbon Drive belts play a role in reshaping the downhill cycling landscape.

Stay tuned for more from the "DRIVEN" series.

 I love this bike,probably my favorite one of the DH WC. Hope to see the new Zerode G3 reviewed along this bike in the future. The electronic sifting to me is a game changer for Pinion gearboxes.

 Deffo one of the best looking DH bikes of all time. Sits somewhere between Turner DHR and Balfa BB7

 make a dh ebike version of this. Does it makes sense here?...

 Nice job, the belt retainer being integrated into the rear drop out is a good idea, though it should probably be replaceable.

That is one really long belt, a tensioner and a pulley, it's gotta have a ton of drag.

I just ordered a Kavenz VHP16MX with a Pinion cradle to replace my Zerode Taniwha MX. I asked about a belt drive but because it's a custom pulley, it's not an easy fix, so I'm just going to use a chain; it's lower drag anyhow so that's not a terrible thing.

Nice to see gearboxes actually enter the conversation, it seems like the time is ripe, esp with the addition of e shifting and a combined motor and gearbox. I'm not advocating for e shift or power assist, I prefer the manual shift without power assist, BUT, increasing options never hurts Smile

 Actually, it kinda' looks like that belt retainer is replaceable, pretty clean if that's the case.

 it is 100% replaceable. It looks to be a sheet metal part bolted onto the dropout

 How does having a long belt affect the amount of drag? None of these pulleys are very small in relation to the surface area of the belt engagement points either. Just curious on your armchair engineering speculations

 @KolaPanda: Longer belt will stretch more, maybe that's the issue here. It will have an effect on power loss, but I don't think drag will also be affected
  • 6 0
 @pooceq: belts don't really stretch. They stretch less then chains when you look at the lifecycle of it.
  • 1 0
 @Serpentras: I think it highly depends on application. In any kind of engine belts are subjected to higher loads in continuous operation for looong periods of time while here on human-powered bicycle the belt will be loaded in lower frequencies with lower torque and for much shorter time. While belt needs only dead stupid tensioner because it is quite stiff, chain requires a bit more sophisticated/delicate device because it is flexy. Just my opinion. Chain provides more efficient power transfer while it's clean. Belt probably doesn't suffer from sensitivity to heavy contamination at the expanse of being less efficient.

 How were you able to order Kavenz frame with Pinion cradle? I can't find this option at their site.
  • 1 0
 @Serpentras: Fully agreed, belt's strech is such a small fraction of it's length, so you can actually forget about this issue in your drive layout design Wink

Compared to the chain's 0.5-1% elongation which gives you additional 5-16 mm to your drive (chain length this is hudge advantage for the full suspension bikes with a single speed drive (and the gearbox) !

 @fluider: You can read about it in the Blog under their Pinion prototype (Geagon).

Kavenz has had enough interest in the Gwagon VHP to upgrade it to V7 which featured swappable dropouts (+0 to +20

I just ordered mine this morning, 3k USD shipped with +0 and +10 dropouts.

In terms of travel, the VHP16 can run shock strokes from 57.5 to 65, which will net 140-160mm travel.

You can also get the Gwagon in 180mm travel.

 @fluider: I really want to see updated statistics for the efficiency of belts vs chains and the comparison between a gearbox like the pinion and a regular driver train in winter conditions in let's say the parts of Europe that actually get winter.
I want to see how the salt will rip the chains and the derailleurs efficiency, haha.
I can not imagine how much mud and all the crap we get will make it worse. The statistics I know are only made without dirt. It shows that chains will suffer when they get longer.

@sanchofula: , man I really don't like the look of the Kavenz, if it would look better it would be a instant buy for me. There are not many gearbox bikes out there. What a shame. Because of that I will stai longer on the derailleur camp but with the twist of the Nicolai Nucleon.
  • 1 0
 @Serpentras: I'm saying about comparison of power losses between belt and chain. It doesn't matter if we'll compare power losses on standard drivetrain, or gearbox drivetrain. If belt was as efficient as chain I'm sure the belt producers would always be markiting it.

 Gearboxes are the solution the bike industry is too scared to dive into. Too many companies would be out of a job if this was adopted. Hope Gamux sticks with the best looking (and functioning) bike in the WC Circuit
  • 1 0
 Gearbox adoption is coming along, e shift and e drive are pushing the change. I feel like a late adopter, I only started riding a Pinion two years ago starting with a Nicolai Argon HT, after that experience I was sold.

I've been on a Zerode Taniwha MX for a year and it's a great ride, though the geo and suspension are kinda old school.

I'm upgrading to a Kavenz "Gwagon" Pinion VHP16 MX in the new year, and it's gonna be awesome!

The more gearbox bikes to choose from, the more likely folks are to give it a whirl.

Most any high pivot can be "gearboxed" with minimal changes, that's how Kavenz did it using their standard VHP design.

 @sanchofula: I am planning on going gearbox this coming year as well, have not decided on what bike yet though.

 @joelsman: hollar at me if you wanna chat, there’s some discussions on mtbr that might be worth reading.

I’m hoping the Kavenz will ride well, it’ll be interesting to see how a Horst link works for what is essentially a single speed.

Geometry is so user specific, I’d say that choosing a Pinion bike is kinda hit and miss unless you can demo or specify your preferred geo.

In aluminum, Kavenz and Nicolai will do custom geo.

In carbon, Instinctiv and Zerode are the best choices.

I’ll have my Kavenz VHP Pinion in February, that’ll be an interesting to my Zerode single pivot.

 Check out the Kavenz VHP Gwagon, coming soon, 150-180mm travel, DC compatible.

 This is by far the most interesting bike on the WC circuit. Great stuff - keep going Gamux!!

 electronic shifting on that Pinion box as well. This bike is the future.

 What prevents the belt from sliding laterally off the idler and other gears?
  • 12 0
 If you look at the pulley wheels, each tooth is actually a cross. Lateral teeth engage the drive on the belt, longitudinal teeth keep the belt centered on the pulley. The belts themselves have a split down the middle of each rib to engage with that center tooth on each pulley. IIRC this also helps with belt retention at lower belt tension, which reduces drag on the system.

 Would love one of these with the motor in the gearbox too as there's no uplifts where I live.

 Awesome machine! I love to see companies actually implementing new technologies and advancing the equipment vs doing a paint change or small changes to geo and charging $12K!

 I'm almost exclusively a mud rider. My next full sus will be gear box.

 @mattg95: my main gripe with traditional cassette drivetrain is I have yet to have owned a rear hub where either the freehub bearings, or the internal hub bearing closest to the freehub do not fail/explode during sloppy winter riding. With the paul WORD hub you only have the outboard bearings, and they seldom fail due to their dimensions.

Actual clogging of the cassette/derailleur system has only happened in wet snow
  • 1 0
 @Ynotgorilla: DT Swiss 350 I've used was pretty well sealed against mud. I've clogged up pulley wheels on my mech many times, but the hub needed service once in 3 years

To be fair, my issue was with clay and sand, so this could be a factor here

 Effigear solution doesn't need a tensioner, see here:

 Really nice idea but it also requires a single pivot bike with the pivot placed exactly in that spot. Its great for Starling but bad for any other design. Even the Gamux has a pivot that is too high.

 Yes but then you have low anti squat

 That one has the integrated fender and is rubbish. It makes an insane amount of noise and collects rocks and debris. I tried it for one day and ditched it on mine.
