Upgrading the wheelset on a 1983 Fuji conversion. I want to stick with 27" wheels for aesthetic reasons and also because I don't want to buy new brake calipers. (Both wheelsets use standard-issue Formula sealed-bearing hubs.)
These are the choices, both from Harris Cyclery.

• 27 inch Sun CR-18 Rim, Formula Sealed Cartridge Fixed/Free Hub, 32 or 36 Stainless Spokes; matching Front wheel: 27 inch Sun CR-18 Rim, Formula Sealed Cartridge Front Hub, 32 Stainless Spokes. The Sun CR-18 is a sturdy double-wall rim with eyelets, 22.5 mm wide (18.5 mm interior width.) $235 for the wheelset.

• 27 inch Weinmann RM19 Rim, Formula Sealed Cartridge Fixed/FreeHub, 32 Stainless Spokes; Matching Front wheel: 27 inch RM19 Rim, Formula Sealed Cartridge Hub, 32 Stainless Spokes. $150 for the wheelset.
The Weinmann RM19 is a single-wall rim with no eyelets, 25 mm wide (19 mm interior width.)

I'd guess the Sun wheelset is sturdier, but it's also $85 more. Is it worth it?
