Should mountain bikers shave their legs?
Lets weigh both side...
Look pro: Shaving your legs is more popular among professional (high level) mountain bikers . so if you are trying to look pro shaving your legs will help
less chance of infection: less hair means less chances of infection, an easier to clean wound, bandages will stick on better and be easier to remove.
Washing made simpler: its easier to clean dried mud off legs
Massages made simpler: use less lotion and its less gross for the person doing the massaging
Don’t Look feminine: out side the cycling world it is considered weird and girly to shave ones legs
Time saver: shaving your legs a few times a week can add up.
No Razor burn: if you are new to shaving your legs, it can happen and be pretty annoying.
I don’t shave my legs, mostly because I see it as optional homework. It might be helping but the benefits just aren’t that noticeable (benefits not worth time). However, I can understand people who do shave and if I rode more and got massages I would shave my legs too.
for your typical recreational rider or entry level racer I'd say don't do it. above that it's a maybe , once you get up to high level pro it seems like they all do it.
