After having problems with my rear hub for the past six months, I continued to have them Saturday, and pulled the cassette off to take a look. Well, I got more of a look than expected, when the entire freehub assembly came off in my right hand, with the hub body (and wheel) still in my left. Both sides had their respective axle end.
And thus, all my strange unable-to-replicate-at-home problems are explained. I believe that I cracked this axle at some point last year, probably with about 5k miles on it, and it just finally broke clean at some point. With a QR pulled tight, it is pretty hard to detect a broken axle, and it only misbehaved under load, which I could not replicate in the shop.
So this brings up 2 related issues:
1. Getting a new axle, and repairing the broken one, and
2. Getting a new wheel entirely, to have a spare.
Am I right in thinking DT Hugi hubs are supposed to be good? We are a light team (270 tops), and I do not abuse the bike, though we have hit the random pothole, have never had a pinch flat or broken wheel out of it. 5k miles is nothing on most of my other stuff, and I expected a tandem hub to be near bullet-proof.
Any recommendations for everyday wheels? Tandems East has various rim/hub combos, but I don't have much experience with them. I am definitely interested in lighter stuff, but if a heavy part is breaking at 5k miles, then maybe I need to check that.
This wheel was original equipment on a 2006 CoMotion Primera.
Are these axles something that can be had readily? I normally do all my own work, build my own wheels etc, but I have not for the tandem yet.
