so the person who is too cool for lock-on grips is astonished that turning the bike upside down helps get a wheel in/out. not really surprising is it?
I’m not too cool for lock-on grips, they just solve a non-existent problem whilst adding a load of unnecessary weight!
It doesn’t make it easier though, that’s the point. I worked in a bike shop for 10 years, I never once saw any staff member (in fact I’ve never seen it in any bike shop) do it. Must have fitted many thousands of wheels.
Can you imagine if pro-tour riders started turning their bike upside down to change a wheel at the roadside, utterly absurd!
