    Got the 167mm axle with 1.75mm thread to replace the thru-axle on a Trek FX S6, and so accommodate my BoB trailer. Works like a charm — like the R.A. Project made it ‘specially for me.

    High quality piece with excellent customer service. Would recommend The Robert Axle Project to anyone looking set their bike up to trailer for the long haul.

    Got this 167mm axle for a Norco Treshold ‘A Single Speed’ .
    Communication was very fast, shipping to Belgium too.
    It works fine with my BOB Yak. The adjustment of the yolk was only minor in my case, only 10mm or so.
    With the original axle I head creaking issues, with the Robert axle not anymore. Tolerances are tight, high quality machining and finishing.

    One note: The outer diameter of the stainless axle end is 20mm, and it barely fitted inside the drive-side dropout. I had to scratch some paint away. Also, I had to insert a 12mm/17mm-ish washer because the radius of the filleting was higher on the inside of the dropout. This was also necessary because the dropout is so wide, half the unscrewing hole in the stainless axle end dissapears inside the dropout. With the washer I can insert an unscrewing tool.

    Good fit for Norco Search XR Steal. Customer Service was excellent, and parcel arrived as expected Canadian Review. 5 Stars and nothing less. Will be making another purchase in the future, for another bike. Just what I needed thanks.
