Saris' Wheel Arch provides a versatile, quick way to store your bike. It adjusts easily to accommodate narrow or wide tires, either front or rear. You can also easily connect additional units to store multiple bikes. The Wheel Arch folds down for easy storage and it comes pre-assembled.
I haven't returned these because they work better than nothing and hanging bikes up is not an option for me. The arches somehow seem move out of their settings at the bases and stretch at the tops or let the bikes topple over if the bikes aren't set perfectly perpendicular to the bases. I have three linked together, store the bikes front wheel only staggered facing west-east-west avoiding handle bar interference. Rear wheel storage results in derailleur/arch contact.
Bottom LineNo, I would not recommend this to a friend
