On my quest to find the perfect CX tire set-up, I followed my brother's advice and went with the Hutchinson CX tires:
Bulldog up front,
Piranha in back - both tubeless ready. I also went with the Stan's No Tubes rim strips for 700c wheels.
I am no stranger to the tubeless way of life, and all my off-road bikes (with the exception of my single-cross) are set up tubeless. With the dry, hard thorns that plague Almaden, it's only practical to go this route.
I decided to do some fireroads and headed toward Quicksilver Mines - a nice system of fireroads and dirt paths that climb to the highest peaks of the area. However, about two blocks up from my house, I hit a piece of glass with my front and sealant started spraying all over the place. I did what you're supposed to do with a tubeless set-up and I pointed the puncture toward the bottom to allow the sealant leak down and seal the hole. As I rode toward the trail head, the hole would spring a leak again and spray sealant, where I'd repeat the process of letting the stuff fill the hole.
I think I took the wrong entrance when I arrived at the trail because those paths are steep and more suited for hiking or a MTB granny gear - not my steep'ish CX set-up. I'm sure a lot of riders could clear it on a compact crankset with road gearing, but I am just a mere mortal! There were a few hike-a-bike situations.
The hole held up quite fine, and after poaching a few illegal trails to get back home, I was able to get to a road descend (Hicks Rd.) where it still held up, even hitting 30-40MPH in some places. Some of the clay dirt caked up in the area, which I think helped seal the hole even more. I'm not sure if my tire is toast, so we'll have to see if it holds up. I hope it isn't... I just installed it last night!
Clay + Sealant
My front tire deflated to about 35-40psi, I'm guessing - which is fine for the trails I was on. On the road, it was a bit frumpy on the climbs, but this was a true test and I wasn't about to throw in a tube.
As far as the Hutchinson tires go, they performed quite well and I was very impressed. The slicker Piranha rear combined with the bite of the Bulldog front proved to be the right way to go, although I did burn out on a few of the steeper areas on the dirt. They rolled fast, which was most important. Some Kevlar protection would've been nice in regards to that piece of glass.
When I arrived home, I immediately grabbed my Stan's Sealant Injector and replaced what I had lost on the trail and it held air after sitting for 30 min.
So far, so good; fingers are crossed. Crossed? Awesome... I did it again, folks!
