Sun CR18 27” X 1 1/8 – 1 1/4 Road Wheel Set

$199.99

Description

The Sun CR18 is as old school as old school gets, when it comes to 27″ wheels, excluding steel chrome plated rims which quite frankly, are better off Not being produced anyone for sake of Mother Earth.  But the CR18 has the same shape as those older box style chrome plated 27″ rims from the days of yore.  The Sun CR18 however, is double wall, aluminum alloy, and has single stainless eyelets, so they should help your ride hold up for another 50 years.  What a relief!  If you want to roll up to the coffee shop on your faithful vintage steed, and blow away all your friends with a new wheel upgrade sporting that classic look, I’d say don’t wait to order.  We have a very limited number of these rims available, and when they’re gone, that’s it.

These road hubs are the epitome of bare simplicity, and that’s a good thing.  The front and rear hubs have a vintage tapered road style aluminum alloy hub shell, steel axles, and use a loose ball (cup/cone) bearing system that is relatively easy to maintain for the DIY’ers.  Please note, the rear hub accepts a 5, 6, or 7 speed freewheel gear cluster, (all of our other road wheel sets/rear hubs use cassettes).

We’re building these up with silver Sapim Leader stainless spokes and chrome plated brass nipples, laced two cross front and rear.  Full disclosure, we’d have preferred to lace these 3x, but the spoke lengths for this rim is one off, and we don’t have a ton in stock.  If you’ve got an old school 27” road bike in the garage, (or attic, or shed), and if it’s in need of some TLC, maybe you should order these up during the Sun CR18 27” wheels and get back on the road.
