I'm a one bike cyclist. Currently that's a Kinesis Racelight T2, described by those more in the know than me as a "winter training bike". I've done 995 miles on it since buying it in Nov 11. That's mainly day in day out all year round urban commuting. I have a rack and panniers quite often with a load of weight in: tools, locks, clothes, laptop, sometimes shoes, work papers etc. Periodically, about once every 3-4 weeks I try to get out for a longer ride (by my standards) which maybe 30-50 miles (without panniers obviously).
The bike came with Mavic CXP22 rims. At 730 miles I had a spoke go on my rear wheel. Evans sorted it on a same day basis so I was able to ride home on it. This morning (265 miles later) I had another spoke go - again on the rear wheel. Took it to Evans but they can't do anything til next week. This was their advice:
- once a spoke has pinged, a wheel is increasingly susceptible to spoke failure. Sounds entirely plausible to me but is it right?
- the Mavic CXP22 is an entry level rim and I should upgrade to the Mavic A719. Including new hubs and build costs this would be £213
- the A719 is an ideal rim for my riding purposes. Apparently it is stronger and lighter than the CXP22s. I should not find myself going any slower (current avg speed for CY2012 is 15.73mph). Is that right? Is there another rim I should be considering?
The thing is, I've commuted for 15 years on 3 bikes and maybe 7-8 sets of wheels (including a bargain set of Bontrager race wheels!) and never had a spoke break before. Maybe I've just been incredibly lucky. If my current rims aren't up to the job, i want to sort it out now but I'd like to make good choices so any advice you can give would be most welcome.
