I see it as the difference between having a Clydesdale
and a thoroughbred.
Yee-ha!

Might be more apt to compare them to belt-driven motorbikes than fan belts. As an idea the '03 Buell XB9R gives a replacement interval of 24000km for the belt, roughly the same as most chain-driven sports bikes.CommuRider wrote:It's still heaps lower than the life expectancy of my car belt though.

& yet my old 250cc Kawasaki gave 50,000 km of faultless service before needing replacement. An interesting design feature was that instead of the drive sprocket being bolted to the wheel, there was a rubber donut that compressed slightly when power was applied. While this slightly reduced performance, it greatly increased the durability of the belt.Trepidious wrote:Might be more apt to compare them to belt-driven motorbikes than fan belts.

I suspect this is the real answer, in that the manufacturer / designer makes a trade off between reliability / durability and other factors such as weight, performance and cost.
Oh & in relation to valve timing in cars, one of the main reasons for belts is that they do not stretch and so maintain much better timing over their life. They would probably last well past 100,000 km, but the consequences of a belt braking are so catastrophic that they are scheduled for replacement well before that is a possibility. None of these factors are an issue on a bike.
Oh and CommuRider, clarks make a nice PTFE coated chain, available in pink or green as well as more boring colours of black, blue, red and white. No doubt it's the wrong shade of pink or green though

Later models had much better belt life (and according to this site they had lifetime warranties) but even at 24,000km it is much better than you will get from a poorly maintained chain. I wish more motorbikes had them!Trepidious wrote:Might be more apt to compare them to belt-driven motorbikes than fan belts.

I've been watching the Gates Carbon Drive with some interest and this bike has everything I want in a commuter and then some. I want one.

Well given the lifetime of Buell, I guess most of the belts did survive the company's lifetime (if you'll excuse the dark humour, I thought the brand and company had a lot going for it). Reckon I'm due for a new commuter soon, I'm still keen on one of these bikes.

All the LBS folks I've spoken to about the bike are really enthusiastic, they reckon it's a great little bike. Shame they sold the one they got - would have got them a few preorders had it been on display methinks.

Very nice , I like the gearing and smooth changes.
I am a bit concerned if I puncture on the commute, I guess I'll have to learn how to take off Alfine 11 equiped wheel before that happens.
Very stealth with the reflectors and belt guard removed.

It's easy peasy as long as you bring a wheel nut spanner! If not it's probably still possible to patch the flat but the degree of difficulty goes up!the grid wrote:Bought an INC 3 had the guys at Jindalee find me one in Melbourne.

All you do is select a middle gear, push the spring back on the hub and pop the connector out (as it's not under pressure). Then, go about your business and fix the flat.the grid wrote:Thanks S

When you've got it all back in place slide the selector spring back again and pop the connector in. It's **really** simple when you know how to do it. Don't worry about it, and when you get the bike get the shop to show you or I will if we meet up sometime.
I actually think it's slightly easier than a normal bike!

From previous experience I expect the Sports Contacts to last me about 6 months before they start getting punctures from the glass and thorns along my route. I've ordered a set of 700x32 Vittoria Randonneurs to replace them and will fit some decent mudguards once they are fitted. Can you get lightweight spanners for the puncture repair kit?
