How narrow tire size ?

[barry g]

Love my 3 yr old Trekking 7.0 (Bosch CX). Always ride on pavement. I'm getting ready to replace the Michelin Protec Cross 700 X 40.
Going with the Schwalbe Ebike Marathon. Does anyone know how much Narrower size I can go (37m) ??
thx in advance

There is a chart on the Schwalbe site. Check the last tab with rim and tyre sizes here https://www.schwalbetires.com/tech_info/tire_dimensions

You have 21mm OEM Alexrims and should be fine with tires widths from 35-62mm.

TIRES - Michelin Protek Cross, 42-622
RIMS - Alexrims MD21, aluminium
