Had some on my bokeh, thought they were pretty good, certainly felt faster, however they were loosing air tubeless with the zipp gravel tyres, took the tyres off to run an extra bit of tape round the rims to make them a bit tighter when I noticed that the rear rim had cracks along the rim edge on the rear wheel, this was only after 4 rides so they were sent back for a full refund. I have since decided to stick with the original hunt 650’s, don’t think I’d bother again as nice as they were, once bitten twice shy.
