Ssshhh! They might charge me for the fence ( I'm serious! ). The Bontrager stem ( with ONE M5 bolt securing the handlebar ) allowed the riser bar to twist upside down on the 2nd flight of stairs. By the 5th flight I've accelerated up to warp speed toward the busy road so I chose the fencing and scaffolding as the easiest option.
Bad bits- I can't work for a while as I've carpal tunnel syndrome ( hand shagged....ouch )
Good bits- Bonty stem now in bin. CAN'T allow anyone to own such a dangerous piece of engineering ( albeit originally designed for flat bars ).
-On-one ( 4xM4 bolt front loader ) stem on until Salsa start making the 2 bolt chromo ones again ( I bought the last one off you: lush+still on the geared Bonty ).
-The Eno eccentric wheel NEVER slacked through the whole thing!
