Training objective: one hour easy tempo ride with the cadence at 80-90 rpm's to recover from Saturday's race Okay, cleaned the bike properly. Then took off the rear wheel and took the tire off the rim. Not much Stan's Race Sealant left in it - just a bit of clear water. Okay... Gave it a bit of a clean out, looked for a puncture - nope. Okay, poured in another 90 ml's of Race Sealant and re-seated the tire on the rim using the high volume pump to get it to 30 psi. Wonderful! Sure is a lot easier to pedal with air in tire, I thought to myself... at least for the first 30 minutes.... then it was obvious the tire was still slowly leaking. By the time my 60 minute ride was over the tire pressure was down to 10 psi. I hate to use a tube for non-emergencies, so will take it into the shop tomorrow to see if it's the rim or what. Crap. :(
