Cyclometer calibration for 406 rim with 28x406 tire
Am I correct in assuming the 4 digit number for calibrating my Sigma
cyclometer would be between 1550&1555. Did roll out and computation.

My homebuilt FWD recumbent -- http://piotrowiak.info/poziom jid:live_evil[]jabber.ru gg:6373907 I think a 28x406 will be closer to 1520. (approx 59.7") Of course with higher inflation pressure and a light rider the number could be higher. Did you sit on the bike to do the rollout? gotbent aka FRVT rider

As a point of reference, I do a rollout of 3 rotations at normal tire inflation pressure with me on the bike and then divide by 3 to minimize error. For an Avocet Freestyle (44-406 - 20 x 1.75), my number is 1527. For my Schwalbe Stelvio (28-406 - 20 x 1.125), my number is 1451.
