Mini-velos often use less common seatpost diameters and seat clamp sizes, so we’ve put together a quick reference here.
Velo Orange Neutrino:
SEATPOST: THOMSON ELITE SEATPOST / ELITE SETBACK SEATPOST (31.6mm / 367mm)
SEATPOST CLAMP: THOMSON SEAT CLAMP (34.9mm)
Crust Bikes Stupid Tourist
SEATPOST：*THOMSON* ELITE SEATPOST / ELITE SETBACK SEATPOST (27.2mm/330mm)
SEAT CLAMP：-
For the Stupid Tourist, no seat clamp is required because of the Ritchey Break-Away System. As for seatpost length, I recommend choosing the 330mm option over the 250mm to be on the safe side.
All models of Bike Friday
SEATPOST：*THOMSON* ELITE SEATPOST / ELITE SETBACK SEATPOST (27.2mm/250mm or 330mm)
SEATPOST CLAMP：*THOMSON* SEAT CLAMP (31.8mm)
All Bike Friday models use the same size listed above.
For the seatpost, use a 27.2mm model with the included shim. The required length will vary depending on the rider, so it’s best to choose based on your saddle height.
(If you’re unsure, you can’t go wrong with the 330mm option.)
Hope this helps!
