did you mange on your road bike? What gearing do you have on rear cassette?
Respect - same as my new one so I'll have to try the hill - never dared on my old bike (27 or 28).
Been up on MTB - bottom gear and a grind :-)
Yep it’s a tough one, spent most of it out my saddle. Especially since it carries on gradually climbing for a while after the steep bits
