A wide range of helmets from a selection of manufacturers other than the usual bell/giro/bontrager/etc. I’d travel to get a helmet that fitted and be willing to pay rrp. Same goes for shoes and gloves.
I like mavic, endura and madison clothing. All good vfm and suit most people’s needs across a wide range of disciplines.
For other stuff I’d like an lbs that stocks the things that you need the day of a ride in case of a problem. Good tyres in appropriate sizes, rear mech at slx/xt level, chains, tyre sealant, freehub repair kits, bearings, bottom brackets and pedals.
