If you got a problem, yo they'll solve it. Small job, or big job without the right tools and knowledge it can make you hate your bike. Sign up and if there's a bike stand free prop up your ride and get your hands dirty. It's just off Spadina on Toronto University's main campus. I had a back wheel problem and after a few visits I converted a $50 mountain bike with crusty gears and a broken axle to a workhorse single speed ready to bike courier some tasty meals. Extremely cost effective and a grade A helpful staff you can't go wrong with any kind of bike when you get there!
