Hey all,

I'm running a 29er MTB frame with Salsa forks on 700 x 35 tyres and I get a BB height of 288mm

What is deemed a normal range for BB height on touring bikes? Oh I am using a 175mm cranks too.

I'm very interested in a switch to 650B wheels which are 38mm OD smaller on the bead, so 19mm lower on BB height if I switch wheels assuming the same tyre profile height. This would give a BB height of 269mm with 175mm cranks, does this seam to be too low?

I like to ride back roads and dirt / gravel tracks when touring.
