I have updated the Tyre/Chainset information for the “Fat Race” 26″ Fat bike. The frame can now handle 29+ tyres too! I have set out what tyres you can run with each chainset 3x 2x 1x (and the ideal chainline).
I have also worked out the tyre compatibility for each tyre with different size rims (100, 90, 82 and 65mm).
Worth a look because this information is relevant whichever Fat Bike you ride. www.traversbikes.com
