    Wheel Flex?

    Hey folks. Sorry if this has been discussed, but a quick search didn't turn up anthing obvious.

    I was riding my fixed conversion yesterday and while taking a corner, the front end felt like it moved over like and inch or two. I though maybe the tire was low, but it was fine. The head set is fine and everthing else seems fine except the front wheel flexes alot. If I'm standing over the bike, I can move the rim over a couple of centimeters laterally in either direction. I tightened the bolts around the axel, but it didn't change the flex at all. Does this sound like a really flexy wheel or is it a sign of loose spokes or something else? Any advice is appreciated.

    Sounds as if the bearings are waaay loose.

    A few mm seems plausible, but a couple of centimeters?!?!

    Either your bearings are really loose (which would cause the wheel to wobble and bump and probably make a lot of noise) or your front spokes are really really loose, or the front wheel isn't installed properly in the fork (very dangerous).

    Try taking the wheel off the bike in order to diagnose this problem. Does the axle have a lot of play in it? If so, overhaul the front hub... hopefully you haven't trashed the bearings already. If not, check the front wheel for trueness and roundness. It's hard to believe that the front spokes could be so incredibly loose without coming out of true.

    okay...a couple of centimeters is an exaggeration now that i think about it, but i know that i can move it at least 1 centimeter without that much effort. the quick release is on the fork is really tight and the wheel is pretty true. the axel doesn't seem loose, but i'll ake a closer look. i think i'll overhaul the hub like you suggested and see if that helps. if not, i'll have a professional take a look at it and if worse comes to worse, it's an excuse to buy another wheel. yeah! more toys...less money in the bank account!

    Yeah, take it out and check the axle by hand. Maybe the tension on your spokes just needs to be increased, but 1 cm of wiggle-ability does seem way too high to me.

    My Spinergies used to flex about 5mm either way and rub the brake pads when I used to stand and rock the bike.
