I’ve had quite a few adjustable travel bikes (not on the go changeable mind), the funny thing is that I very rarely altered them and always used maximum travel.
One thing to watch out for is that if you plan to match the (adjustable) fork travel with what is set on the frame, the BB can end up being far too low. This is what stopped me from buying a Nicolai…matching the travel with a fork of similar travel is fine, wanting to use it with an adjustable travel fork isn’t because of the A-C height changing.
EDIT: Not sure if all that makes sense, but you might see what I mean. 🙂
