Bearing focus: Deviate Highlander/Claymore Bearing Service
Posted by Jim MacPhail on
This week we changed the pivot bearings on a Deviate. There's a couple of unusual features on this bike, including a concentric pivot wrapped around the BB and an idler wheel with true dead-end blind bearings. These necessitated new tool designs, so it was a fun one to work on. We've collected the tools that we used here. Though the process is demonstrated on a Highlander 150, the Highlander 2 and Claymore follow similar designs and use the same bearings, so the same tools should be applicable. The first task was to remove the main pivot tube. The inside bore...
Bearing focus: SRAM DUB BB30 bottom bracket
Posted by Jim MacPhail on
Today we're examining the process for changing bearings in a SRAM DUB BB30 mountain bike bottom bracket. It's likely that many of SRAM's DUB BB will follow a similar pattern, so this post may still be useful even if you have a different model. Puller Selection We currently offer three designs of bearing puller; the wind-out type, the blind wind-out type, and the tap-out type. The wind-out type needs access to maneuver the tool's inner drift behind the bearing. Unfortunately in the case of this DUB BB there is a flange that prevents access behind the inner race of...
Evolution...

It’s been all change here at BearingProTools over the past year! I’m amazed at how the time has flown by, and excited for what the future holds. At the very end of last year we moved to a new workshop, a necessary step to facilitate what was to come next. After a month or so of fit out the new workshop was ready for the main event, the arrival of a brand-new CNC lathe. As luck would have it the delivery was made on the coldest day of the year, and believe me, it’s not easy to manoeuvre a...

Friday Night Special - Manual Milling a Stem
Posted by Jim MacPhail on
What do bikers do with machine tools at the weekend? Make bike parts of course! New 40mm stem made on the 1950's manual mill. Milling a rectangular shape with a few holes in it is easy enough. Forming the curved surfaces takes a little more thought and preparation, but it is well worth it in the end! Can anyone guess what the inspiration for the shape was?
