Blackspire Twinty 2X Chainguide
Designed to be the most efficient 2X chainguide ever produced. Made in as few pieces as possible and has no moving parts.
Works well, fairly quiet. Can not notice any chain drag. Manufacturer says not to use dry chain lube due to certain minerals in it. Only wet, kinda a bummer, since ill will be cleaning the chain more regularly. But still solid component.
Nice Chainguide. Very smooth & I can barely hear it. Great price & a simple install. No dropped chains & such a quiet ride!
