I have a hybrid bike I use for road biking almost every day. After 3 trips on rental mountain bikes I started to think about buying mountain bike as well.
And here comes a question about proper sizing and fitting. Let say I try a bike on LBS parking lot and it “feels right” from “roadie” prospective. Should I go for one size smaller despite my “feel” because it may not be right?
Even after my short experience I think that mountain biking is quite different from road and, as skills develop, smaller bike may be better fit. Or not?
My particular situation: I am 6’5”, my hybrid is 22.5” Trek 7500 and I like how it fits. Rented bikes were 21” ( 29er) and 20” ( yes , too small, but nothing larger was available in rental shop – it also made me thinking about buying vs. rent). For my own bike I plan to check several brands in 21”-23” size range.
