The new Stem adaptor allows your WeeRide to fit to any bike with less than 5mm space under the headset or an over wide top tube (over 45mm).
It means WeeRide now will fit 99% of bikes out there.
Please tighten so bar is secure in to adaptor channel. Please do not over tighten as it could then affect steering.
The only bikes WeeRide are aware of that the adaptor wont fit is some Giant bikes with 31.8mm stem, normal ones are 29mm. These Giant Bikes use the Overdrive 2 fork. This is the information from GIANT:
Overdrive is 1 1/8th at the top, ie 29mm. Overdrive 2 is 1 ¼ at the top. Ie 31mm.
The only bikes you will find Overdrive 2 are high end road bike and cyclocross bikes for the current models.
