I've gone through
four five frames in the last decade or so, all from different manufacturers, all steel but both lugged and welded both steel and aluminium. Every one of them has eventually developed a crack, and the steel ones have been repaired and then re-developed more cracks until I give up and get a new one.
It's usually on the seat tube down near the bottom bracket, but once on the down tube near the headset, and
once twice on the chainstay.
I generally just use the bike for commuting (~150k / week) and occasional weekend riding - all on the road. I've been on my mountain bike for the last couple of years, but I miss my skinny tyres and I'm thinking of getting a new road bike. So is there anyhing I can do to make it last longer than a couple of years or should I give up and just stick to mountain bikes?
Does this point to there being something wrong with the way I ride? Do you think doing track stands at lights would exacerbate the problem?
Edit: Here's a list of the manufacturers whose frames I've broken:
- City Cycles Sydney (steel, unknown origin, but it was really nice)
- Cecil Walker Melbourne frame (steel, Ken Evans, a well-respected local framebuilder, custom fit for me, again, very nice)
- KHS (steel, Korea, kinda cheap and nasty)
- Kona (aluminium, Taiwan(?))
- Soma Doublecross (steel, America, from the weight of it I thought it would last, but no).
Seems I don't buy bikes, I rent them.
