Surly Steamroller owners...

Put bigger tyres on to increase the BB height.

(...)

The headtube is steep already (except on the smaller size), there's less rake than a typical road bike, just how much slower do you want your Steamroller to handle?

I am currently on 23c tyres. Do you know how much BB height a rear 28c and front 25c probably will add?

I got a 62cm Steamroller so 74° for me. How much do 3-5mm less rake affect the handling?
