I’ve no issues admitting it, but I definitely don’t ride fast enough to warrant these ridiculous things…I’m saying that as someone who regularly returns from rides with cuts up my forearms where the brambles have caught me as the trails I’m riding are so overgrown. I wear gloves so my hands aren’t too bothered.
The overgrown shrubbery can be stopped grabbing brake levers by simply having your finger behind the lever (does make it slower to then pull your lever as you need to move your finger over the the lever, but as trails that overgrown aren’t being ridden at lightspeeds, that isn’t really an issue).
I’m genuinely unable to see any proper use for these on a MTB other than pure fashion, which thankfully I very clearly don’t follow, so don’t feel the need to consider these (but equally feel the need to post up my dislike and disdain for them so that others can judge me!).
