So Hubby goes for acl surgery this fall AND they have said we will be having a El Nino winter here in California. I figured when my hubby is up to it he will want to get back on his bike asap but if it is raining alot he might not be able too. So i was thinking for christams I would like to get him a trainer he can set up in the garage and work on getting his stregth back. Now he has a mountain bike not a road bike. Do any of you snow bunnies who get stuck inside for the winter have a recommendation for this device I know nothing about?
