The wheels balance very easily on the scales, I’d seen someone else do it on the forum and it took all of about 5 seconds
I should add that the rims are actually 30.45 which is great for when the tyres stretch a little.
I used clinchers on mine and broke a plastic tyre lever and 2 tubes until I did this - I hope it helps others.
Pop on one side and then put in your tube. Wrap a bit of tape around the valve because it’ll rattle when youre done where ithe valve meets the rim. Once you’ve popped the tube in all the way round you need to make sure the bead of the tyre is in the centre of the rim. With the other side of the bead proceed to pop that over the rim and when you get to the last bit, stop and make sure BOTH sides of the bead are in the middle ‘dip’ of the rim around the whole tyre. If you do this, when you get to the last part you’ll be able to fit them by hand, don’t do it and you’ll break tyre levers for sure.
Hey, I hadn't actually measured mine, but they are indeed just a bit wider. Mine are rim brake, I just checked and front looks like 30.5mm and rear 30.3mm. Better yet I guess! This way a tire up to 29mm wont go over 105% "rule". Yours will probably stretch and get closer to that number, so you should be fine.
I was also the one balancing both wheels like that on page 3
I only had tubeless tires on mine so far, but it does look like these rims are aimed at being used as tubeless instead of tubed. The center channel is reasonably deep and shoulders are high to keep beads in place, so when my tubeless tires poped in they did a loud bang. Not the most practical design for tubes, but great for tubeless.
I had to remove the tires and place them again, and I could do so without levers, even though the Vittoria CS are said by many to be the hardest tire they ever had to place, and I had to work and pull the tires from the opposite side towards the valve, and both beads had to be in the center channel. Yet, no levers needed. It looks like if I need to put an inner tube inside those tires I'd get a sweat and possibly pinch them too...
But the upside is that there's no way the tire will come off even if you flat mid corner. Looks really safe. Even when totally deflated the beads stay in place tightly. I bet it would be possible to run regular clinchers as tubeless on these rims if one keeps pressures low enough, unless it's a loose one. Please let me know in a month if the beads of your non-tubeless GP5k have stretched or if they are still popping and doing a good bang on these rims! Because you know, why not risk safety to save 160g from the wheels?
You can decide, if you want a texture like Campy AC3 or not - I skipped it, as it is only a tad better in wet conditions and a bit worse in the dry. Nothing really noticable.
Up there I pumped the tire again and went down safely.
