Wheel Flex: How much is too much?(5 posts)

Wheel Flex: How much is too much?LD
Nov 7, 2003 1:19 PM
OK, I've got a Reynolds Ouzo Comp Fork and Mavic Cosmos wheelset. When I stand and hammer, or simply lean into a turn at speed, the wheels flex noticably: My computer magnet whacks against the sensor on the fork leg.

Riding in a straight line (or on the stand), the magnet passes about 3 mm from the sensor, so the wheels are flexing at least that much in each direction.

Is this amount of flex on a wheelset (6+ mm) normal? Is the front wheel going to simply taco in the middle of a 50mph descent?. Am I too big for those wheels (200 lbs)? Am I just over-reacting?

I am 168lbs and when I stand and hammer the front wheel ticks. Not real loud like a KNOCK. Just a tick. I thought it was a spoke or something. The LBS said it was the magnet hitting the sensor due to wheel flex.

I have learned to live with it.

I had similar problem at 215 lbs. Switched from Ouzo Comp fork to Woundup and no more problem. Also, those wheels are okay, but there are stiffer ones.
it's your fork nmgtx

I weigh 135 pounds. I've never had this problem. I ride an Ouzo Pro, Look HSC 1, and an Alpha Q Sub 3.

Heavier riders definitly need to pick their equipment accordingly.
