I bought a new Marin Fairfax SC4 with the gates belt drive. I’ve only ridden about 1800km on it, but one of the teeth has broken off the back sprocket already. It kind of looks like the belt doesn’t fit the sprocket right, like a stretched chain, but I don’t see how that could be. Any idea what would cause a tooth to break off? Is the belt too loose? The dealer told me not to tighten it anymore then they had it.

Hello,
The snub wheel on my carbon belt has just given up the ghost, Near as I can figure there were two ball bearings held in place by spring. what I can’t guess at is how this spring was held in place as the retaining hole has no sign of cap and there are is no sign of threading for a possible holding bolt. I have searched the internet but can find no where to buy a replacement wheel kit.

Salve, posso chiedere: quanto sono limitato nel numero dei rapporti tra cinghia e catena con Roholoff?
Per grandi salite, viaggi in zone montuose è meglio belt o chain su Roholoff?
Quali aziende producono telai compatibili per cinghia roholoff? Quali mi consigliate?
Soma Wolverine, SURLY ECR, altri, and?
Grazie,
Alberto.

In reply to Nic Christie. Nic, Did you upgrade to CDX? I cracked my back CDC sprocket and would like to upgrade but it's flat here so I want to go from 1.9:1 to 2.5:1 as I never go below 4th. FYI for others reading this the Alfine 8 is 1:1 in 5th.

In reply to Roberto. My wife has a CDX on her Trek Soho that the Gates calculator says should fit and it has a faster gear ratio (2.5) than mine (1.9) which I would love to change as it is generally flat here. Going to see if it will fit before I buy. In the meantime my LBS put a chain on for only $50CND, so as for the cost comparison for me the chain wins, but I will go back to a belt for the low maintenance, no worry about calf tattoo when I get to work, and the superficial appearance of the red CDX belt on my red and white Scott.

In reply to Greg Robertson. Hi Greg, I think you will have interferences with the frame, but from a functional point of view there's no drawback for adding some spacers.

In reply to Roberto. I am thinking about changing out my CDC on a Scott Sub 10 to CDX as I have cracked the rear sprocket after about 4000 kms and the belt won't stay on. Is it possible to put spacers on the rear axel on the Alfine instead of the crank? The front sprocket is close to the frame already.

In reply to Alee Denham. Really sorry for the late reply. Thanks very much for your advice and suggestions. Unfortunately in the last 2 years life has got in the way and this project has not progressed, but it will hopefully do so soon.

In reply to david1024. The Gates belt system is obviously not for you.

It is interesting to see people here seems to prefer the newer CDX Centertrack over the original CDC Mudport belts and sprockets.

I have two bikes with both belts and love the CDC more than the CDX as the CDX once a while makes noise because it seems the centre of the sprocket touches the belt. Never experienced that for the CDC.

That is only one observation but here in the Netherlands, most of the professional bike builders seems to favor CDC over CDX, see for instance Riemaandrijving on santosbikes.com
