|I have been having this recurring problem with slippage of my rear skewer on a used bike I picked up. When I stand up to sprint the rear wheel torques over and the tire rubs on the chainstay. It does not happen every time but once it starts it will not stop. I keep tightening the skewer to try to get it to bite but have no luck. I have exploded two skewers so far, one steel and one titanium. Boy that titanium one went off like a gun shot! Anyway, I had the frame checked and it is true. I also checked the axle and it is not too long. I have tried moving the wheel around in the drop out, adding a washer to increase the surface area, and of course extreme tightening. The drop out is chromed so there is no paint to rough up. Any suggestions would be appreciated.|

|Had a Lemond Zurich with chrome dropouts and had the same problem. My best recommendation would be to get a set of "real" quick releases, prefereably Shimano. These work infinitley better than any aftermarket ones made. You could also try filing the chrome off the surface where the QR attaches, both these solved my problem.|

|Ti in the back is no good for a strong rider. Some after market skewers don't have knurled faces on both sides and this lends to slippage and ever creaking, I know because I went through it with a set of steel Salsa's. Get yourself a set of Dura-Ace skewers and your problem will disappear.|

|That's the first time I've heard about Ti skewers in the rear as being bad. In fact, I'm considering about buying some replacement skewers and did note that some have Ti for both front and rear and some for just the front. I thought that was kinda strange.
OK...so please elaborate for me...I would be considered a strong rider (heavy, big gear masher, ride lots). Would you expect me to have a problem with Ti skewers (a) rarely (b) good chance (c) guaranteed ?
What is the problem that occurs? They just slip? Or do they actually break?
Thanks in advance!

|That it stretches(has a low modulus)therefore it is difficult to get them REALLY tight.|

|I've had Cook Bros. skewers, steel front, ti back, for awhile, and I've never had any problems. They screw down nice and tight, and the shape of the cam makes for a very satisfying lockdown. Now, they are ridiculously priced (I thought I was getting a discount I didn't get -- it's a long story), but, if I had to compare, they lock down better (more definitively may be the better description) than Mavic or Shimano. Not that it matters a whole lot, because the others hold the wheels on fine, but the Cook Bros. are better. And the Mavic's, which I got with my wheels, retail for about the same amount, I think.|
|For most applications they are fine||J.S.|

|But he was having a problem with slipping and it is a known quantity that Ti doesn't lock down as well and flexes more that steel. That's the reason your front Cooks is not made of Ti, it was intended for a suspension MTB fork and Ti just flexed to much for that application. As far as Cooks being better, well I have tried just about everything on the market and Shimano Dura-Ace(XTR) are the best I've used with Salsa a close second(best aftermarket).|
|Have you tried Control Tech's Ti non-QR?||Gary|

|OK, if Ti allows the spindle to stretch too much, thereby making it sometimes difficult to tighten using a quick-release lever...would using the non-quick-release style work?
The CT's I looked at use a 5mm allen wrench to tighten. And surprisingly, the pair of them weigh 41 grams!

|its got kyseriums with the skewers that come with them...when i try my old control tech ti they are fine but i want to keep the kyserium ones on so i really tighten it and it goes away...i dont want it to blow though...i have a trek carbon with the unpainted dropouts..is it ok to tighten them down pretty tight|

|If you are a sprinter type, do yourself a favour, and, like the above posts suggest, go D.A. and smile:)|| |
