The bike chain is a symbol of the bicycle. The connotation that is held between the bike and the chain is nested so deeply that it is iconic. The chain is synonymous with the bicycle. This fact is for good reason too, the bicycle chain has used the same basic design since the early 1980s. Yes, they have become lighter, stronger, narrower and more efficient since then, but ultimately we are using the same basic technology.
Over the past decade or so, there has been slight diversification from the traditional chain drive including a
hydraulic drive and
shaft drive among others. None have really caught on though. Well, now there is a new option. Myself along with everyone at Norco is pretty excited about it- The
Gates Carbon Belt Drive. Gates has been making automotive belts for decades and has made the shift into the cycling world.
There are three different Norco models for 2010 that are using the Gates Carbon Drive. There is a 29er Singlespeed mountainbike, a Singlespeed urban commuter and a 8 speed, internally geared commuter. What are the advantages of such a system without a chain? Well there are no moving parts in a belt so lubrication is not an issue and there is no mechanical wear on rollers resulting in 'chain stretch'. The belt is efficient, light and durable offering many advantages over the traditional.
I will be honest, before riding a belt-drive I never noticed the mechanical nature of a chain. I always thought that it was smooth and efficient. Well, throwing a leg over the
Judan the only way I can describe it is fluid. The liquidity of pedaling motion is silky smooth and seemingly effortless. The last time I tried something so drastically different was the first time I rode with disk brakes. All of a sudden, the standard that I had grown up with , v-brakes, was obsolete - an underpowered, high maintenance paperweight. Could the Chain also succumb to this plight?
There are certain things about a singlespeed bike that take some getting used to. Taking the
Jan Ullrich approach to cadence instead of the
Lance Armstrong technique means that climbing is a one way ticket on the Pain Train... But, who doesn't like a challenge right? Plus, with no gears, cables, lube or chain there is very little to go wrong. After a few rides on the Judan, It hurts a bit on the ups and the gear can top out on the downs but I am coming around. The climbs are building strenght and the high cadence seems to be evening my pedal stroke. Also, coming from a 26" wheel, the 29s make the bike seemingly float over everything.
There are still some advantages to the chain. The obvious one is that it works with a conventional rear derailleur while the belt drive is locked with an internally geared hub or for those who dare... Singlespeed. The only real way to decide is to try it for yourself. Swing by your local dealer and throw a leg over!
