Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Belt-Drive System...Beuler

http://www.carbondrivesystems.com/overview.php?lang=us

This seams like a great idea. I've been thinking about how I could incorporate this into my future Schwinn Le Tour III singlespeed conversion. Has anyone ridden a bike with this system on it.

I took a test ride on one of those Treks myself, I kinda liked it. Quiet and smooth. Basically did exactly what they said it would. I'd like to get one if there were more options for the parts.

Sorry, no conversions allowed with a belt drive. You need a special dropout to get the belt through the rear triangle.

I would really like to get a hold of that belt drive material and see what it feels like.

Yea that's what I assumed, but idk how it could feel more "carbony".

IDK if I ever built up a single speed I would want to check this out... hmm my gf kind of wants a single speed maybe I can test it out on her.

been riding a belt drive motorcycle for a decade....love the no maintenance well except when the belt fails then your screwed because it isn't something your average shop keeps on hand. However I did 30,000 miles on my belt or about 6x what a chain could handle so factor that into your thinking.

Its still possible, but you'd have to cut a gap in the triangle, then fit some kind of bolt on thing to fill the hole.

I guess, but is it really worth the effort? I mean, unless the belt drive is the greatest thing ever, I can't see it being worth compromising a frame.

I don't think it is either, but that wasn't the question.

I guess its not the most practical thing in the world. But I do like the idea.

...Although watching someone have a heart attack when you tell them that you're thinking about sawing through an old Pinarello would be pretty entertaining. Filing off derailleur hangers just became not so bad.

one thing to note is that you would probably need a custom belt, which could prove to be pricey.

Belt drive: solution looking for a problem IMO. Chain drives are very efficient, low cost and can be field repaired. You also don't need to have a special frame. Tell me, why would I need a belt drive?

well they give their answers to that question right on the site... http://www.carbondrivesystems.com/whycds.php?lang=us

i think they could be a big plus on a winter ice/snow bike. that reeks havoc on my chain. i think the bigger reason is to diversify. in order to make something that will sell, it either needs to be a) better, b) cheaper, or c) different... preferably 2 of those.

Not having to clean my chain after every rain/snow would be nice. Though I wonder how these would hold up to skidding, i.e. if they'd have the 'rigidity' to lock the rear wheel up.

I know their marketing spiel and none of those are compelling reasons to make the switch IMO. Maybe on a townie because of the clean factor, but then again I just use a dry wax lube on my townie and it's just as clean.

One of the big places they are trying to market these is to the MTB world and feedback seems to be that if your set up isn't spot on you'll have issues (dig around MTBR.com for reports). The other thing I've heard is the noise when riding in dry, dusty conditions. Solution: "lube" with a squirt from your water bottle. I prefer to save my water for drinking when I'm out on the trail.

All that said, I haven't ridden one so take my opinions for what they are worth. If people want to buy into it, great, but I'm not convinced there's a need for me to make the switch and I suspect many others will feel the same.

BTW, I ride in snow and ice all the time and have no problems with my chain. A KMC Rustbuster runs about $12 and is great for those conditions
