Recently purchased a new Flow EX wheel set, two TK 2.2 tires, and a bottle of Revo. Unfortunately, I only purchased one bottle, so I've ordered a second. I've completed the front tire with no problems. Since the tires were new, I mounted both and waited a week for them to stretch. Had to use a tire iron to mount, but wasn't to difficult. Both tires seated with a hand pump. The front tire held air, but was flat the next morning. For the back tire, I could hear several air leaks and was flat within 30 mins.
For the sealant, I followed the conti videos, first prepping the inter part of the tire with sealant and used a brush to spread. Mounting the tire was easier, but still used a tire iron. Filled tire with 120ml of sealant, air the tire to 40psi, and as of this morning, it's holding air just fine.
Hopefully, I'll received the second bottle of Revo by next weekend and will try the rear tire. Since it had several leaks, I'll be interested to see how it seals.
