Ergon GP1 Biokork on Brompton M/H handlebars
I have a question for those of you who have a Brompton M or H style and the Ergon GP1 handlebars (regular or biocork).
Do you have to cut some rubber off the inside edge of the grips to install them? Or do they just fit without any cutting?
And specifically for the biocork, if cutting of the grip is necessary, is it hard to do on the biocork? I assume the regular rubber ones are easy to cut with an exacto knife, but I'm not sure about the biocork ones.
My searches have indicated that cutting of the Ergon grips is sometimes necessary, but nobody has mentioned cutting of the biocork.
Any insight is appreciated. Thanks.
