From what I've read, (thinking bout putting risers on my s type) you can put any 25.4mm bars on, with 45mm rise being about the same as an m type hight
Been looking at getting wider bars and I reckon you could easily add 40mm without affecting the fold
As long it’s 22.2mm all the way to the clamp rather than 22.2mm at the grip area as the Brompton stem is very wide to the point that’s it awkward trying to slide the bar through.
what renthal bars are people using on their bromptons? and am I right in thinking they are to give some rise to S types?
