The grips are Ergon GX2's with magnesium bar-ends. I needed proper grips and this was the only one available at the shop at the time. They don't affect the fold as the bars rest on either side of the folded wheel.



The only issue I've had with them is that they're long, and the stock Brompton brake levers have a plastic wedge that doesn't let you align the levers to the edge of the grips. (You can see what I'm talking about from the picture I posted.)



For someone with shorter hands like myself, it's a pain trying to shift gears. Originally, the plastic wedge was over the original foam grips. Other people have ended up cutting their grips to make way for the ledge, or you could buy shorter grips meant for grip-shifters. I like these grips too much to give them up so I ended up changing the brake levers for Shimano R770's instead.
