Larger frames with 26" wheels are going to look really funny - like a folder.

Surly should take it a step further and increase the rear spacing so you can fit a nice wide flange spacing, dishless rear hub. With Shimano mtb hubs you need ~143mm to do this. perhaps they could even bundle a custom rear hub and BB to go with this unconventional geometry.

They should go ahead and switch to disc brakes. If you're going to risk losing the 700c devotee market, why not go ahead and piss-off the canti lovers too? Route bosses for full housing run along top of DT and left CS.

I agree with previous poster, I can do without the spare spoke holder - and the pump peg, and I rarely use the chain hanger (always forget it's there).

Get rid of all the extraneous decaling (I vote a decal headbadge only). Include a decal sheet instead for the marketing-addicts.

IMO the colors seem to always be terrible. They're so consistently bad that the original pea green is now considered one of the best. The cherry red was nice too.

While I'm at this virtual redesign, get rid of the DT bosses, and move them to headtube sides (won't be a problem with disc brakes).

I think a larger diameter biaxially ovalized downtube would stiffen up the frame a good bit too, without much cost or weight penalty.

Water boss locations should be rethought a little too. Combined with a bottom clamp FD, it may be possible to fit 4 bottle bosses on the main triangle on larger frame sizes.

Closing idea - integrate rear rack into rear triangle design - save cost and weight. Come up with a better front rack design than the 1350g / $150 (with shipping) Nice Rack.
