I suffered from the missing 5% with my front D+ puncturing twice (first one 1km from the start of the main event
) and a knackered spare inner tube which turned the first repair in to a good 30+ mins, the second visitation (same wheel) was a bit quicker at 20mins but I can see the attraction of tubeless in you don't have to spend ages worrying and trying to find the cause of the visitation etc....
I still haven't found the cause of the second visitation, but when I get round to cleaning the bike I will take a good look just in case its lurking in there ready to pounce once again!
These SON Plus wheels are almost like run flats, I hadn't noticed for a few moments or two it was flat - must have been tired!
On the plus side I received my carbon forks for the CdF today, they had been on order since September, could have built them myself in that time! LOL
