Has anyone else found differences in Q and chainline among the 50.4 cranksets? I swapped in a Sugino PX with shorter crank arms in for a V-O, and found less clearance to the chainstays on both sides- at least 2mm per side.
I prefer the look of the rare Sugino, and sorted front derailleur issues required by the swap. A bit fussy to set up with 46-30 and similar chainring doubles, as no front ders were made for it. -- Harry P Travis Portland, OR USA 14.6 On Jun 7, 2021, at 10:38 AM, 'Will Horton' via RBW Owners Bunch <rbw-owners-bunch@googlegroups.com> wrote: Thanks everyone for all the feedback. Really hard decision overall. I ended up ordering the SUNXCD cranks in 172.5 and 46/30 from veloduo. I really wanted 44/30 or 44/28 but that range was out of stock. I almost went for the cloverleaf chainring version as they had the gear range I wanted but I really prefer the 6 arm style I think.
