PaRtZ Posted November 13, 2008 Report Share Posted November 13, 2008 hmmm. not sure what to think to be honestIn terms of trials im going to say no. And im going as far to say in terms of XC im not sure. Commuters + leisure bikes yes though Quote Link to comment Share on other sites More sharing options...
Mat Smith! Posted November 13, 2008 Report Share Posted November 13, 2008 How do you put it on/shorten it?And is it not just as likely to snap as a chain.Mat Quote Link to comment Share on other sites More sharing options...
txt2007 Posted November 13, 2008 Report Share Posted November 13, 2008 why's everyone trying to replaces the chain, what's wrong with it?!I guess for commuters these new chainless bikes have theyre advantages but personally i won't be moving from the good ol' chain untill they create a bike that moves using brain waves...

liam-pantera Posted November 13, 2008 Report Share Posted November 13, 2008 when i watched that video most people were making the comment that it felt very resposive , but then i noticed that all the bikes had chriskings on and in all the pictures . My point is that shurly thats makes the pedal stroke more responsive , another disadvantage of the belt drive is that they have a slipping alowence but i would think that aslong as the belt is maintained and well reinforced it would be safe . i would happily try it Quote Link to comment Share on other sites More sharing options...
ogre Posted November 13, 2008 Report Share Posted November 13, 2008 Singlespeed, no good for international stock compsYou've got to cut your frame to get the belt onsingle speed is allowed everywhere now?the frame needing to be split will make any frame useless for impacts, unless you had something like that onza with the crazy chainstays.poo the smallest sprocket is 20t...

Mr Motivator Posted November 13, 2008 Author Report Share Posted November 13, 2008 single speed is allowed everywhere now?Really? News to me, I thought it was a min of five working gears. I've been out of the scene for a while! Quote Link to comment Share on other sites More sharing options...
Tim-Rodriguez Posted November 13, 2008 Report Share Posted November 13, 2008 Should be interesting when a stone gets caught in between the belt and the gear... Quote Link to comment Share on other sites More sharing options...
bigamac Posted November 13, 2008 Report Share Posted November 13, 2008 http://www.carbondrivesystems.com/installation.phpThey are made for a specific frame if you clicked the link in the first post.I personally think it would be useless for trials.

NVWOCI WVS Posted November 13, 2008 Report Share Posted November 13, 2008 I like this. I think it's a really good idea. Not a new thing though; belt driven bkes have been around for a while. There are more pros and less cons than with a chain as far as I can tell. This system coupled with the dropped chainstay, like the onza prototype would be great for trials.

Greetings Posted November 13, 2008 Report Share Posted November 13, 2008 I also like it. These belts are bound to be quite strong, generally belts of this kind are, when designed for a specific purpose of course. I hope this catches on and they eliminate the need to cut your frame in half to get it on. It looks like you could also fine tune your gear ratio with one of these. And if the ones used on that website weigh 80g, imagine how strong a 300g belt would be. Quote Link to comment Share on other sites More sharing options...

Skoze Posted November 13, 2008 Report Share Posted November 13, 2008 MotorbikeThe return of the Risc brake!!!!I reckon it'd be awesme! As Inur said, if these are supposedly as strong as a standard chains and weigh 80g, a heavier, beefed up version could be insanely strong! If only they could work minus the frame cutting Quote Link to comment Share on other sites More sharing options...

Reinis. Posted November 13, 2008 Report Share Posted November 13, 2008 I hate chains, since mine snapped in a drop gap. Don't know when the belt system would be available for everyone, but I'm really waiting for it! Quote Link to comment Share on other sites More sharing options...

RossMcd Posted November 14, 2008 Report Share Posted November 14, 2008 If that can suspend an 800 pound harley off the ground then its definately capible for trials.Only thing i would see a bit dodgy is that the belt might slide off the rear cog if it doesnt have anything to keep it on. And dont car engines also run these type of belts? Quote Link to comment Share on other sites More sharing options...
Jaffacakes Posted November 14, 2008 Report Share Posted November 14, 2008 Yep, cams and fans.These belts will be ultra stong. They wont snap, just eventually wear out and start sliding.Its a Good idea IMO but I deffently cant see it catching on in trials. Quote Link to comment Share on other sites More sharing options...
bendy Posted November 14, 2008 Report Share Posted November 14, 2008 I wouldn’t trust it how often do you have to change a cam belt? and how often do you have to change a cam chain? the main reason car companies started using belts over chains is cost and noise reduction from what I understand. I wouldn’t trust a belt with my teeth I enjoy food to much also haven’t other companies brought similar things out? getting parts will also be difficult unless it becomes common. would the tension damage the hub bearings at all as I would guess that you have to run a much larger tension than you would with a chain.bendy Quote Link to comment Share on other sites More sharing options...
Pashley26 Posted November 14, 2008 Report Share Posted November 14, 2008 Imagine on a road bike, thats going to be almost silent. Which is kinda cool. Quote Link to comment Share on other sites More sharing options...
Spider Lad Posted November 14, 2008 Report Share Posted November 14, 2008 Nobody has raised the issue of efficiency or actual power delivery yet. Everyone knows they use belt drive on motorbikes but I don't see these things being used on Moto GP bikes for example. I'm guessing for the two reasons I've already mentioned.

Jamie_Neal Posted November 14, 2008 Report Share Posted November 14, 2008 would the tension damage the hub bearings at all as I would guess that you have to run a much larger tension than you would with a chain.I'd be a bit sceptical about this as well. Its bad enough if you get an overly tight chain.Also, if you feel like a change of ratios, you can't just add a couple of links.However, I think it would be interesting to give one a go although i don't fancy a dropped stay bike (like Onza) or cutting a slit in my frame. Although the method they've used looks ok and the amount of frames about nowadays with the rear dropouts bolted on/adjustable by bolts I would think that it wouldn't bee too hard to get something to work.
