OT: are Shimano Alfine chainring guards size specific or universal
? Would a 45T guard work with smaller chainrings?They are size specific if you're using a dérailleur at the back (have to clear the chain when you shift into the higher gears), but the big guard would work with a smaller ring (albeit looking silly) on a single speed or hub gear.

Cheers, until couple of days ago I thought they are SS/IGH only, but then saw that Shimano lists them as 9-speed. Now I see that buying and converting R550 crankset for a 1x9 drivetrain was a mistake since I could have gone for Alfine straight ahead. I will try if the 45T guard will work with a 42T ring, if not I will grind down 42T ring for use as a guard with 39T ring.

Here is a similiar idea with IGH and discs for commuting, but not as tight geo. Geometry shown with the dimensions of a Ritchey WCS fork. Still didn´t get around to build it as I would need about 500 Euros just for the NuVinci wheels. I did however pass on a really nice NuVinci wheelset with belt drive components about a year ago on E-bay and regret it now...
