I don't have enough leg hair to worry about but it's just enough to prevent bandaids from sticking, or to interfere with using a percussion massager and topical analgesics. So once in awhile I'll use the old Norelco when the leg muscles get sore from running -- rarely from cycling. With the Norelco you can even shave over minor abrasions and cuts -- don't try that with a razor. But I haven't used a real razor in decades. I'd consider it if I got serious about time trials or tri-bike stuff.
