The Rock Bottom frame is the base for all our modular enhancements. The ISCG05 mounting style will only work on bike frames with at least 2 ISCG05 mounting tabs.
The frame provides the rigidity required for 1000 lbf (4500 N) impacts while being as light as possible (60g).
Our beautiful raw machined toolpaths catch and reflect light adding bespoke bling to your bike. This avoids environmental impacts from the toxic chemicals used for anodizing.
Mounting provisions are machined to allow the attachment of chain guides, chain catches, and chain tensioners often without requiring the removal of your cranks.
Three sets of threaded holes allow a better chance of mounting and replacing the chain catch through the openings of your chain ring.
