I'm wondering if it has to do with you having a '14 grom. I'm betting the monkey fork tubes are only comparable with the 17+ year model groms. I don't know this to be fact, just spitballing.I'm not so sure about the forks now - I have a '14 Grom and a '19 monkey and was about to buy the black tubes but the tubes on the monkey are slightly shorter (or longer, can't remember) by like half an inch, and also I measured the space between clamps on the tree and there was also a difference of about a quarter inch one way. Maybe this matters or maybe it doesn't? - but with the tapered forks I would think it did? Can anyone confirm that the black euro tubes would work for an OG US grom, and explain the difference in measurements?
