I’m looking at a Sunn Modular S2 and as usual I find myself in a toss up between the small and the medium so anyone got any experience? I’m 5’6″ with a 30″ inside leg.

Unfortuantely since they went bust the Sunn website now looks like this

so I’m assuming there’s not much help there

I recently bought a Modular S1 in large. I’m 5ft 11 and three quarters…

CRC sent me a medium by accident. I run my saddle at 74cm rail to centre of BB for xc and the medium was just too small and cramped for me to ride comfortably – though as a play bike it would have been fine (wrong geometry though) so it went back. Really nice bike though, shame they haven’t any left

The frame is quite compact for a XC bike

I would say you could go for either but as the S2 is rigid and seems more set up for XC than hooning you might want to be a bit stretched out? If so the Medium will suit you best

Thanks, that helps 🙂
