850c with TSDZ2 - wheel size choices Help

[Andy Vickers]

Hi, finally finished fitting my TSDZ2 to my Carrera Vengeance

Problem cycling through the wheel sizes as my bike is 27.5 but that isn't a choice?! Only increments of 1 from 14 to 30.

from the photo it looks as if you have 52-584 tyres. if so, the wheel diameter is only slightly more than 27" (688mm=27.09"). I'd suggest you go for 27" then.

Cheers. I have done.
Seems weird that everywhere I've looked gives 27.5 as a choice . Incl PDF for the 850c

You can buy a cheap gps speedo to calibrate the TSDZ2 but 27" will be more than good enough.

Thank you
