Return of the Elevated Chainstay

In relation to belts and motorcycles. I think if there was a measurable advantage with a belt over a chain that one of the Japanese MotoGp teams would have picked have picked up on it?

Cars, motorbikes :? hardly apples and pears. Maybe I could chime in with the amount of kit I work on thats belt driven but I feel it would be irrelevant. From what I pick up on the ever reliable net, there are folks that have tried it and there are folks that have an opinion on it.

Similarly here too. and that as Dr S says, a Rohloff hub or other hub gear system is heading very close to my dream bike design, and it it is an e-stay as well. Just ditch the big fork at the front and have suitable geometry for a normal bike like my early 90's bike

Yes, belts are in tension, but in other applications they work, so why not bikes, technology is moving on all the time, but as to thoughts of crap getting caught between belt and pulley, well my experience is belts should be covered to stop any chances of things getting stuck between belt and pulley, so we might even see a return to the old enclosed chain guard like bikes of yesteryear, enclosed guards for belt drive systems, thus removing the chance of abrasion from the terrain.

But just to indicate some materials once not trusted now preferred, carbon fibre, ditch metal altogether and go man made materials.

I'll have my Belt Drive within a few months, will let you guys know how it turns out in real life.
For me the Rohloff is a keeper, no more Derailleurs for me ever again. Internal gearhubs (or brackets) are the furure...... do we have any cars or motorbikes out their with derailleurs or any "open gearbox" nowadays???( Sure you guys will pop up with something )

Want to try the Gates Belt on my new 29er (Grove) to see how or if it works for me, if it doesn't, I can switch back to a greasy chain again, no big deal

i'm pretty conservative by nature (never used suspension becuase it doesn't suit my needs.....yet) But allways willing to try out new stuff to see if it makes biking more fun for me.

One thing about belt drive bikes is that they need a stiff frame to work properly. Some recent frames have had problems with the belt slipping slightly under load when the frame flexed too much. Also the sprocket and chainring sizes seem to have some bearing on the efficiency too, larger being better and less prone to slipping.

E-stay frames aren't stiff enough for a reliable belt system imo.

i have seen belts on bike that are used in very harsh conditions, snow, cold temps of -40 etc......they are meant to be good for thousands of miles too.

ti motorbike chains are way cool.....think of the weight savings

Hope that was a joke gibble :shock: surely they would stretch too much

Ah but GG, you're clearly forgetting those hig performance belt drive machines already out there. May I refresh your memory of the Kawasaki GPz 305 and Mlwaukee's finest, the Hardly Ablestone.

That van nicholas looks good but why the chainstay protector
