The Philcentric is an Outboard Bottom Bracket that gives you eccentricity without using horizontal dropouts, an eccentric hub, or chain tensioners. You may be required to use a half link. If you need to order replacement dust cover please note that the Philcentric uses our medium dust covers.

Please note: All Philcentric Outboard Bottom Bracket cups require the Phil Wood Philcentric installation tool and alignment gage (available separately).  It is recommended that you go to a bicycle shop familiar with the installation and adjustment of this part.
