dumb rohloff question
dumb question, but has anybody put a rohloff speedhub on a 700c wheel? i was looking at their online speedhub finder and they don't list it as an option. the literature lists some compatible 29in wheels and the spoke length, but no 700c rims.
thanks!
thanks!

Interesting dropout/track ends on that frame. Nice way of getting chain tension & ease of service on the Rohloff.

EDIT: It's listed as '28 Zoll' on the Rohloff site.

700c is hardly a 'metric' size, nor is 28" the imperial size - they are 'names' for the size... the metric size is 622mm.

If you use Spocalc: https://www.sheldonbrown.com/rinard/spocalc.htm , it already has the dimensions of the Rohloff hub built in. All you need to do is select the hub, your chosen rim, and it calculates the correct spoke length for however you want to build the wheel.

The mish-mash of names and sizes was finally rationalized by the European Tire and Rim Technical Organization (ETRTO) which defined wheel sizes by the rim's bead seat diameter so a "700c" rim is defined as 622 mm and a "27"" rim is defined as 630 mm.
The outside diameter of a current 700c rim with a 23 mm tire is about 668 mm but when the size was first named, tires weren't that small. However, a 39mm tire on a 700c rim would be about 700 mm in outside diameter.
