I finally got my 27.5+ wheels built and tyres delivered. I even got the rear tyre to go up tubeless! The wheels were intended to go on the Cotic Solaris but just out of interest i tried them in the Singular Swift frame not really expecting them to fit but they do! so a quick swap of brake rotors and cassette and i was off for a test ride. as per the full fat bike the chubby (3") tyres are very pressure sensitive and will take some time to dial in the correct psi. but first impressions are good and i might use this bike for an upcoming 24hr race.
