My Haro X3, a pretty old bike. I haven't ridden it in probably a year and a half since I have my 29er now that I use for longer rides. It's in the house to make more room in the shed outside

.
Has some cheap alloy pedals after the stock plastic ones cracked under normal riding. Also redline chain tensioners after getting pissed off however many times trying to get that back wheel straight with proper tension, I really need to get a full half link chain to use the tensioners correctly though.
I have lines and fittings to make the whole lower brake setup completely dual (from the lower gyro to each brake arm). I was having problems with not being able to center the wheel in the brake arms or one side pulling more than the other and one pad would rub. I really need to get that setup. Oh, and I guess I bought the soft pads because they squeal hella loud when braking.
Here's my previous bike, Haro backtrail X1. Always thought the frame looked cool. I ovalized the rear hub just jumping those plastic ramps you could buy from like Target or wherever. 14mm axles front and back and 48 spokes I don't think I had any other wheel problems.
I can't manual at all, but could do pretty long wheelies on the X1. Once I got the X3 I can't do them anymore. Not sure if it's the compact gearing affecting me or frame geometry (final ration is pretty close so it shouldn't really matter), I can't even wheelie on my 29er now.
