One of things I like about a mountain bike is the more upright sitting position and less weight on the wrists. I also have those little "bull horns" which helps when climbing or pushing hard.
Decided to do some maintenance on the winter bike, and noticed the rear spokes were all loose! Couldn't really turn them, so sprayed with some penetrating oil. Was able to turn a couple but not all. Decided to take the rear wheel off and quick release was not moving. Some squirts of oil and just got it to move and then loosened to get the wheel off. Still kind of stiff so decided to remove it from the axle...well the skewer is seized in there. Tried to muscle it with a wrench and broke it right off a few mm in the axle. I probably should have found a nut to put on instead and call it a day.... Took the axle out by loosening the nut holding the cone and I was careful not to lose any ball bearings, which were in good shape. Figured I would go to the bicycle shop and see if they had an axle and skewer if not, I will put it back and just use a nut (defeating the quick release, which is not that important). I still have to deal with tightening the spokes. I've never had that happen before not sure how I rode last winter with them loose, the wheel was not true, but I wasn't too particular as I thought all those curbs and pot holes in the winter, who cares.
