  Be careful, contrary to reviews, there is no mounting key with the box, I chose this model for this reason and now I can't mount it...

  Haven't had time to mount it yet, but this case looks good upon unpacking. The bearings seem to be of good quality and the manufacturing is very clean. A tool is provided for mounting (tool to be used on a 1/4" ratchet) Mounted on Leon Torrentibus (I will correct it if there is a reference error but I am quite confident).

  Exceptional value for money! I didn't expect such smoothness of the bearings and finish of the casing. Really surprised and I thank the brands for still offering us such great products at such prices!

  Bottom bracket mounted on a Semita frame from Léon. Good design of the bottom bracket with good bearing protection.
