Hi Michael,
I can address the part of your query --I was wondering if anyone has a SRAM DUB crankset or any other direct-mount crankset on their Rivendell. I've been reading about the DUB cranks and they seem actually simpler with fewer parts than a traditional 5 bolt crankset-- Based on my experience with the SRAM NX Eagle 1 x 12. During the pandemic I was doing a build up and found myself short on matching drivetrain parts, unable to acquire what I needed, and tired of matching/mismatching bits & parts for 2 or 3 x 8, 9, 10 cassettes and so broke with tradition and installed a NX drivetrain on a Gus. It required a DUB BB tool, an additional 12 or 13 links to accommodate the loooong chain stays and a couple of 2.5 mm shims to accommodate the BB. The operation was smooth and flawless and I was impressed by the ease and simplicity of installing the entire unit. I realize your question is directed towards the SX, but my experience with the NX has been quite unexpectedly positive. Hope this adds to the conversation, Al On Monday, September 12, 2022 at 2:39:21 PM UTC-4 Garth wrote: > SRAM mtb cranksets start at 169mm for q factor, the Eagle SX is 173mm.
