Confused by this...- 51.8mm chain line for boost 148mm O.L.D. frames
16 Jul 2019
Please could you help me. Looking to fit onto a surly disc trucker, would this fit? Assuming it has to do with the chainline and wider size of BOOST hubs. But thought that BOOST was pretty new and Alivio is kinda old?? The two just didn't sit right with me. Any help would be greatly appreciated.

Many thanks
Hi there,

Unfortunately, as we do not stock that bike we cannot say whether this will work or not im afraid.
