Anyone know what circumference I should have on my computer for 26" wheels?

208 IIRC - it's been a while though and it'll depend on the exact tyres that you're using.

by 208, do you mean 2080? It currently says 2050...

It'll depend on the exact speedo - sounds like yours is working in mm compared to mine in cm but yes, I'd imagine that 2080 will be right

Actually, it's not that critical - 205 to 208 is around 1.5% difference - is your speed accuracy that important? 🙂

not really. it was showing 6 miles for a journey that is 5 miles (according to mapmyrun.com). As it used to be on a road bike and now on my MTB, kinda makes sense.
