You don't need masses of gear to go climbing.
Two options:
Climb as a pair, climbers use half ropes, carry shoes+hardware on rack (one large pannier bag should suffice), helmet on head and rope tied in mountaineers coil on back.
Using one full rope, split the gear, one carries rope, the other carries most of the hardware.

It'll be far more comfortable with panniers.
