I tried #Ergon GP2 handlebar grips today on my #Brompton (M bar, 2023 version) - and I have mixed feelings. 😒
After removing the stock grips and trying to fit the GP2's, the realization came pretty quick: they are roughly 1cm too long. So, I cut them to the right size (as a lot of others also did).
Now they fit nicely, but since the horns are using up space on sides of the grips, my (large) hands don't have enough space and now my thumbs collide a little with the shifters.
