RooiWillie Posted August 30, 2012 Posted August 30, 2012 This is all good and well that we can get all these bikes... They also look so pretty. But with no local distributor for Gates, no viable alternative to Gates, we are screwed here in Africa...
nathrix Posted August 30, 2012 Author Posted August 30, 2012 CONTINENTAL BITING INTO BELT DRIVE GAMES WITH BIG TEETH http://www.bikerumor.com/2012/08/30/continental-biting-into-belt-drive-games-with-big-teeth/ http://brimages.bikeboardmedia.netdna-cdn.com/wp-content/uploads/2012/08/20120830-201719.jpg Continental is getting into the belt drive game, becoming Gates’ first competitor in the (mass market) chain free bicycle drivetrain market. The Conti Drive System should be available early next year. It shares the quiet, maintenance free operation of the Gates belt drive but gets much taller teeth on the belt to reduce the amount of tension required in the system. This adds efficiency and makes it easier to pedal. Contitech’s rep says this also makes set up easier, doesn’t put as much stress on the bearings and could allow the use of cheaper bearings for price point bikes. It uses Aramid fibers rather than carbon because it’s more robust against crimping. In use, it’s not that big a deal, but it reduces user error during installation. Word on the street is Gates is switching to Aramid, too. It can go down to a recommended 24T minimum cog in order to maintain the belt’s life. Because the tooth profile is taller, it does mean the cogs will be slightly larger diameter than bikes using a Gates belt. That said, they’re using an open standard industrial design that’s common, so others can make belts and parts for the system. They hope this will drive innovation for these types of bikes. And Gates’ belts will work on their gears, too. They’re working on adapters and cogs for various internal gear hubs, too. http://brimages.bikeboardmedia.netdna-cdn.com/wp-content/uploads/2012/08/20120830-202313.jpg Note the slack in the belt, which is perfectly fine in this system. They make the belts for some BMW motorcycles and transmission belts for cars, so this ain’t their first rodeo.
Wyatt Earp Posted August 31, 2012 Posted August 31, 2012 Great stuff for the commuter market and the light distance riders.
RooiWillie Posted August 31, 2012 Posted August 31, 2012 Hmmm, quite interesting! I had a look at conti belts when I did my initial spec and calculations. It will be interesting to see what it will retail for...
RooiWillie Posted September 3, 2012 Posted September 3, 2012 ooh... so what is in the box, and at what final cost did it come?
divernick Posted September 3, 2012 Posted September 3, 2012 Belt drive is a solution to a non-existent problem. It's cool cos it's different. But I'll stick with a chain, thanks.
nathrix Posted September 3, 2012 Author Posted September 3, 2012 Will be very interesting to determine for myself how long the belt drive last and the type of rides it works well/or not compared to chain drives. If it's crap it's easy enough to convert the setup back to chain drive . Gates CenterTrack46 tooth bicycle pulley front 4 bolt26 tooth bicycle pulley rear120 tooth bicycle beltkrikit tension gaugestrap wrench tool This combination will give me the exact ratio as a 32t/18t chain set up. I didn't choose 32t-36t/17t-16t chain setup as my poor little legs are not strong enough and I'm happy/comfortable cruising along with 32t/18t ratio.
nathrix Posted September 3, 2012 Author Posted September 3, 2012 some nice machining going into those rings Yes, I must admit, I'm quite impressed.
nathrix Posted September 3, 2012 Author Posted September 3, 2012 Belt drive is a solution to a non-existent problem. It's cool cos it's different. But I'll stick with a chain, thanks. I don't see belt drive as a solution to a non-existent problem at all, just trying something different and sharing all the information to those who are interested. So what bike are you fitting this to?
Hairy Posted September 3, 2012 Posted September 3, 2012 I don't see belt drive as a solution to a non-existent problem at all, just trying something different and sharing all the information to those who are interested. You ass a is not an acceptable answer
