|Fixed = Destroyed Knees....||Macho Man Savage|

|Are fixed bikes as bad as they say for your knees? I'm thinking of getting one just for training - not city riding - so the stopping and starting would be kept to a minimum. Any thoughts or experience?|
|Big gears??? Probably...||biknben|

|Those who mash big gears run the risk of knee strain. I doubt it matters if it's fixed or not.
Pick the appropriate gear for your terrain so that you can go up the rises at a cadence that won't destroy your knees.

|you can ruin your knees by mashing too big a gear, or by braking with your legs. Both can be easily overcome (ride appropriate gear and use your brakes).|

|... and my problems with knees have consisted of one encounter with IT-band friction syndrome. That episode happened when I rode the hilliest century I've ever attempted (Solvang) with cranks 5 mm longer than usual and the seat jacked up about 1 cm taller than usual, on a bike weighing 40+ pounds and carrying a 10-pound pack, and riding platform pedals. Recovery was stretching exercises and a few months keeping rides to 40 miles or less.
I had a friend who once wrecked his knees by off-road motorcycling (he was an ISDE-rider). His doctor prescribed bicycling as a way to STRENGTHEN knees.
I'd recommend keeping your cranks on the short side (most trackies ride 165's), and be sure you don't set up the seat height to over-extend your knees. Whatever pedal arrangement you choose, be sure it is comfortable and properly aligned. Fixed-gear requires either toe-clips or clipless, so it is not possible to move around on the pedals like I can on the cruiser's platforms. This makes bike fit quite critical.
But if your bike is set up to be comfortable, and you avoid insanely high gearing, I believe you'll find fixed to be fine. In fact, it is probably no more likely to cause knee problems than a geared bike: all of the fit and comfort cautions apply equally to gearies.
