2.0" on the front, 1.75 Smart Sam on the back below
Thanks for the info! However, looking back on this, those kinda sizes seem far too big for this frameset. I'll just pick up some Knards and leave huge tyres for another bike.
Any reasons not to go for the Knards over similar cross tyres?
Reasons not to get them: you ride in a lot of really muddy places, want gumwalls, can get the ~equally sized WTB Nanos/Clement X'PLOR/Conti X kings/?? cheaper or you care about UCI cross rules...
2.0" on the front, 1.75 Smart Sam on the back below... apparently clearance is tights at the back, possibly slammed back in the dropouts.
CTBM says Smart Sam is the biggest for Cross Check too... http://www.charliethebikemonger.com/schwalbe-smart-sam-700c-x-47mm---28-x-175---the-biggest-tyres-to-fit-a-surly-cross-check-2158-p.asp
