How do I remove the rear sprocket from a Gates Belt drive system

It's probably stuck because it's digging in to the freehub body splines. Install just the lockring without any spacers. Use your cassette lockring tool to immobilize the freehub from turning, and use ...

Gates carbon drive on carbon frame

There is no reason a carbon fiber composite frame could not be built to accommodate a Gates drive. CFC can be bonded to a metal split dropout no problem. CFC frames designed for Gates drives are ...

What's the deal with Rohloff and Gates Carbon Drive?

Rampant Guess: Given how much Rohloff likely values their reputation (the hubs are hailed for their longevity under poor conditions) they are likely being extra cautious as the set up might produce ...

Do split frames for belt drive bikes need special screws?

Looking at the Gates catalogue, they do not make bolts for frames. They do not sell bolts for frames. Different frames use different split systems to allow the belt in and NONE OF THEM ARE ...

Do split frames for belt drive bikes need special screws?

It is a bolt, not a screw. The difference is that a bolt has a matching thread in the receiving part, whereas a screw cuts it's own thread. You absolutely require a matching thread in the part for ...

Gates Belt Drive+Rohloff - What rear sprocket do I need to help me get up hills and mountains better?

With the existing 50T chainring and 19T cog your gearing ranges from 19.8 gear inches to 104.2 gear inches (assuming 622 wheels) So you're essentially loosing about a gear at the top end and gaining a ...

Can a Pinion bike work with an indoor direct drive trainer?

No, sadly that hub won't be compatible with the trainer. Your trainer expects a cassette of 9-11 or 12 speeds, which presumes a chain. Full specs are at https://www.garmin.com/en-US/p/701670#specs ...

Is it normal to need to re-tension drive belt (Gates CDN) after few days?

The belt itself is supposed to be very dimensionally stable, which more or less bears out in reality. Eccentric BBs are fine in terms of being a sound design and way of tensioning the chain, but ...

Alfine 8 vs Alfine 11 Gates CDX chainline?

Are there compatible longer cranks available for Gates CDX CenterTrack (5-bolt)?

Don't. This is a terrible idea. Saddle height must be absolutely correct, it is the most core bike fit adjustment. Even if you are able to fit huge cranks meant for 200cm+ people to your bike, it will ...
