Before I begin, this is the bike I'm talking about:
During this past week, I've broken(snapped) 1 axle, and bent 2 new ones.
The local bike shop has now refused to give me new ones, saying that I need a new type of wheel with a cassette axle. Runs about $50 - $85, not outrageous(?), but a lot for an unemployed student.
I should note that the first axle was the first axle the bikes seen, and lasted maybe 600 miles. The 2 bent axles lasted maybe 3 each. I'm not offroading, but each of the new axles I used for a pretty aggressive hill climb, and broke as soon as I got to the top.
This bike has had a badly bent frame, the local shop fixed it a few years ago, and it's been fine since.
This bike spent the winter in the bike shop storage, because the chain broke 8 miles from my house. The bike shop said it was due to a bent hanger, which they fixed.
After the first new axle bent, they kept it overnight to look it over. They said the frame was still true and they didn't see any problems with it.
So, should I upgrade to the new axle, or is there a special type of axle that won't break when I use it? I should also mention that the new axle was a temporary fix. They recommended I get a dual suspension bike, to the tune of $1200 - 1500. I'd like to eventually do that, but being an unemployed student prevents it.
Also, before I posted I noticed VERY descriptive titles. I'm new to this website and to other people that care about bikes. If I made this in the wrong section, please let me know
