Scoox Posted April 29, 2013 Report Share Posted April 29, 2013 I am looking at rear hubs for my new mod build. I notice the new edition of the Echo TR hub has a 10mm aluminium axle, whereas the previous model had the same axle but made of steel. I am not convinced Echo implemented this change to reduce weight but rather to cut costs. And indeed the new model is about £10 cheaper. I read elsewhere that a guy had broken two Echo SL rear hub axles. Now if the SL has a 12 mm aluminium axle and it can break, how does the new TR hub design make any sense?? I actually have the new TR hub on my Echo bike, as it came fitted from the factory, and I think it's not good. Although it hasn't broken, the built-in grub screw chain tensioner bites into the axle quite bad. I had to put a bit of steel between the axle and the grub screw to prevent this.
