I'm considering this frameset, but the publicized max tire clearance is a concern. For long races, I need the comfort of bigger tires. Has anyone had luck fitting something like a Clement MSO 40? How tight was it?
Hello, I am considering to buy a Nature Boy disc 853 but I have the same doubts about tyre clearance as The Mickstar. Any feedback about 41mm Surly Knard on a NatureBoy disc 853? I am asking againg on this thread beacause the 853 has a shorter chainstay so probably also a different tyre clearance.
I'm currently running Panaracer GravelKing SK 40s (which actually measure ~43mm) on Easton R90 SL rims (19.5mm internal width) on my 58cm Nature Boy 853. No issues. My gearing (41x17) has the rear ~2/3 of the way back in the dropout. You can see some pics (with a Clement MSO 40 installed) here...
I have an 853 and a regular old Nature boy both discs. I have also run Surly Knard 41's with no issues. I just ordered a set of WTB Resolute tires which are 42's no issues. These are mounted on a set of Mavic 627&927 rims. 27mm internal width. The only comment I have is when the tire muds up chainstay clearance suffers. I normally run MSO 40's on it.
I have both the 853 and 612 disc models. I run Gravelking 38s and Surly Knard 41s (just measured at 40.5mm and 42+ respectively). The Gravelkings fit very nicely, and the Knards fit fine, but I wouldn't want to encounter mud with them. Mostly because one is a file tread tire and the other knobby, but I also feel like anything much beyond a 40mm tire is too much. If I was planning on mud I would put 35s on it for sure.
