Put the GP5000 on the Genesis. I won't be running them for PBP, just want to try them out.
First impressions riding them around the block they are as expected. Roll fast, fairly comfy for a 25mm. It's a bit difficult to do A/B comparison with the previous tyres as they were 2bliess in 32mm. Was running them at 90psi, probably be fine at 80 however
The GP5000 are thicker / heavier than a Pro One. They are pretty much slick, just a "decoration" half hearted light pattern on the shoulders
I had some trouble fitting them which is worth mentioning
The wheels, as far as I remember, have only had one coating of rim tape since I started running them tubeless, maybe 2 years ago now
The front tyre went on fine. I didn't have to use a bead jack, it went on with fingers. The tyres are as mentioned above 25mm GP5000, the rims are Velocity Aeron. The rims are tubeless specific and listed as istr 22mm internal width. 20mm tape fits tightly and exactly. I some kind of problem with my pump and used CO2 to inflate, but it was straight forward
On the rear however, I had trouble. I tried mounting it with the airshot - fail, with CO2 - fail, clean the rims more carefully - fail, use soap solution - fail
The rim tape was crinkled in a few places. But there had been a tyre on it before that inflated just fine. I decided to try replacing the rim tape. I have a large reel of tape. I pulled off the old tape, cleaned all the latex off the edges of the rim (only tiny bits) Under the tape the internal surface of the rim was pristine. I cleaned it finally with isopropyl and retaped with two layers.
Refitted tyre and it inflated easily with the airshot
Moral is, if the rim tape looks shite, replace it
