Rear Skewer for 2008 Trek 1.2 Road Bike

Hello,

I need to buy a new rear Skewer for my 2008 Trek 1.2 Road Bike so I can use it for indoor training with a roller. The thing is that I have seen some very cheap at ebay but I am not sure which one will fit on my TREK. What is the standard lenght of rear Skewers? The skewers I have seen are all 135 mm long but have have found some that are 140 mm.

Thanks.

Get a 135 mm skewer. An old Shimano QR will do nicely and be plenty cheap.

Ok, I will get a 135 mm then.
Thanks
