Blackspire’s bashguard is really solid and took every sump-out we threw at it without flinching. The upper guide covers a large part of the chain and is stiff enough to ensure top derailments are virtually impossible.
The upper guide is a tight squeeze so it requires careful set-up to ensure the chain won’t catch under full suspension compression or at either end of the cassette. Because the bashguard sits quite far outboard, the chain rattles against it over rough ground. At 134g it’s heavy for an upper-only guide.
