Hey guys and gals. I apologize for my ignorance and will sound silly asking this. I am wanting to change some things on my new bike. I got a 2008 trek fuel e8 I am thinking of changing handlebars. Stem. Grips. Possible the hubs Problem is. I a not sure whT sizes to order if I order them. Again. I am a newbie to this. So pardon the question.

Thanks all.

You'll have to either look up measurements or take measurements on your current parts.

Handlebars - width and clamp diameter
Stem - steerer tube diameter and clamp diameter
Grips - usually a pretty universal fit
Hubs - axle size that fits your frame and fork, spoke count, and you'll also need new spokes and have to rebuild the wheels to swap hubs. With new spokes you'll have to have the proper size for the hub/rim combo

Hope that helps.

The stem clamp (bar clamp too) is 31.8mm with a 1 1/8mm steerer tube.
Any modern grip will fit on any model bar.
The hubs depend on the # of spokes, and if it is QR (which I think it is), or another axle type. You might as well get a whole new wheelset (front and rear wheels) if you want new hubs.

IMO, transferring old rims to new hubs isn't worth the time and cost of new spokes. If they're beat up at all, there's some extra difficulty involved and the finished product may not be as good. It's also not that much more expensive to buy built wheels with the hubs I want, in general.
