I can fix a puncture, as long as I can find it.
Happy to report I found the second puncture back at home today, fixed it up and chucked on the 90mm stem for good measure, and had a blast along the trail and back along the Bridgewater Canal - a very wet and muddy affair with a few slightly hairy moments soaked up by the confident frame of the Marin and the grippy WTB tires. Also great mud clearance.
Did about 18 miles which is ok for me in shoot weather.
Cheers
Stu
