There are two main suppliers of wheels and tyre for the bikes – GRP and Roadies – and the M3R-16 can run on either.
GRPs – The cheapest way to order the GRPs is pre-stuck on their rims with the spokes. The front fits straight on to the M3R-16 hub and the rear fits with the addition of the 3D printed GRP rear spacer.
GRPs are available from Kamtec, see links below:
Roadies – The Roadies tyres can be ordered pre-stuck on rims but they also need the optional spokes to mount them. The front end also needs the optional 3D printed Roadies front spacer fitted.
In the UK Roadies are available from KP Designs – see their web-site here
