So what's the deal with some of these stems not tightening enough on the stanchions? I was going to put some shim stock in the upper clamp. Curious if any of you cats had this prob. These E150 have enough little annoying problems to drive me nuts:madman:
What problem are you having ?, there can be some creaking from the stem of the bike , its casued from the bolts in the stem being dry and the stem to steer tube being dry , this is common on duel crown bikes because the load is very different .
Its not a problem where the clamp is not tight enough .
( Specialized did up the torque on all the upper bolts in the stem to 75" lbs, ---but I feel this is way to tight -----I have had to repair several broken bolts and striped clamp threads for shops around here using the 75" lbs )
I run my bolts in my top clamp at 50" lbs and my lowers at 30 " lbs , and the handelbars at 60" lbs with carbon bars .
These wrap style clamps can easily damadge the stanchion tubes , be carefull on overtighten them .
If you alighn the stanchion tubes up on any duall crown fork by sliding the empty lowers up and down on the stanchions while alighning them you will see how overtightening will affect stiction and drag .
I actually have to add a peice of .010 shim stock in my left side lower clamp at the inside to keep my stanchions alighned with no stiction in the lowers, ----the XL bikes with the longer stanchions are affected slightly like this where the S,M,L bikes are not .
Many longer 7" and 8" travel Duel crown forks will also benifit from correct alighnment like this
