I'm
sure everyone has faced this problem sometime during riding. Sometimes you
will have a bad fall and there is no way you can keep your bars from
slipping in your stem, but it shouldn't happen every riding session you
have. If you are experiencing your bars slipping constantly these are a
few tips you should look over.
1) Make sure there is no
grease inside your stem where the bars are touching. Take your handle bars
off and clean the clamp tube of the handlebars and the inside of your stem
with paper towel and water.
2) Not all bars have the knurling on the clamp bar,
or some just don't help much. Take your handle bars off and sand the clamp
tube. A few people have tried putting grip tape on their clamp tube, how
ever I don't find that necessary.
3) Make sure all your bolts for your stem are well
greased. This goes for all the bolts on your bike. Just cover the bolts
with any type of lubricating grease, this will help the bolts clamp down
tighter.
