How much Will A Trainer Damage Your Bike(6 posts)

How much Will A Trainer Damage Your BikeRyan Oliver

I just purchased a trainer for the winter and am wondering which bike to use on it. I could either use my good road bike or an older mountain bike. Does a trainer fatigue the frame by torqueing it back and forth? I'm also concerned that I will rust the components from the sweat. (I am training for mtn bike racing.)

Thanks,

According to info that I've read, the trainer can weaken a frame and cause damage around the BB and chain stays. I can;t confirm it though.

My experience has been that the trainer will trash your tires, so be sure to use old tires on the bike that will be on the trainer. If you go with the older MTB (which is what I do) be sure to run slicks on the rear; knobies are horribly loud. Also set up a fan to blow on you. When you ride outside there is a constant wind blowing on your form your forward motion. On the trainer this is not true, and you will sweat like a pig. The fan will help and keep a towel handy. It's very common to rusted stem bolts and top tubes on bikes which have seen a lot of time in a trainer.

I have usually found concerns about trainer damage to be overblown. You should wipe the bike down when you are done because sweat is corrosive. As for torquing the frame, the main thing is to either not get out of the saddle or to use good technique out of the saddle.

The biggest damage I ever see is just a worn out rear tire.

This used to be more of a concern when trainers mounted at the fork and the frame was held in place at the BB by a "T" shaped bracket. No concerns now, though with rear-wheel mounts.

Tires will get trashed and without a fan you will sweat all over your bike. There used to be a terrycloth cover that slipped over the brake hoods and attached to the seatpost to "protect" everything. Just wipe your bike off after each session and you should be OK.

I've found tire wear to be the only real effect of trainer-time. Just keep a crappy one around for that. On the sweat issue, you'll find the terry cloth "sweat nets" and clones in most of the catalogs...and the blackburn sweat net in lots of bike shops this time of year as well.

Roll some tape on OLN so you've got some other bikes to watch while your training too....that's of course unless your doing spinervals tapes or the like.
