[RBW] Re: handlebar lifespan?
The only bars I've broken has been crashes prior to this and neither were hi end parts. When I think of it they probably were 6 or 7000 series alu too! In RR39/Summer-03 issue Grant had a very interesting interview with the president and designer of Nitto Mr. Akira Yoshikawa: Q: For a 200lb (91kg) road rider, how light can a bar be made and still pass your standards? A: The lightest is 260g. About 250-260g. If you try to make it lighter than 200g you have to use 7075. You have to use better grade material. Q: So the 7000 series is stronger? A: The tensile strength is higher, yes, but the problem is that, when there is high impact, the 7075 breaks because it's brittle. With the 2000 series, it bends easier. We think it is safer for the consumer if it bends instead of breaking. Q: I've heard that aluminium handlebars should be replaced every five years. Do you agree with this? Even if thy have not been crashed? A: The life span of aluminium is shorter than steel. If you make aluminium handlebars and don't even use it for ten years, it is significantly weaker than when it was new. We know our handlebars and stems are quite strong, of course, but when they are aluminium, it is safest to replace them before they break, or show sign of breaking. It is a personal judgement from the rider, as to when to do this. On 8 Jan, 19:05, Doug Peterson dougpn...@cox.net wrote: Do you replace your handlebars on a regular basis?

There are so many variables in the scenario... I'd guess this a rider issue, not a hardware issue.

[RBW] Re: handlebar lifespan?
Dustin, A touch of grease at the sleave could take care of the creak. In general, Nitto handlebars are very well made and should last at least 15-20 years. Of course I'm assuming that you haven't crashed your handlebars and that your not sized like Hercules :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.
