Last night while I watched Stage 9 of the Tour de France I converted the front wheel of my road bike to a
tubeless setup. I went to bed too late to get out this morning so my first ride will be later this evening. However, thus far everything looks good and the tire held air just fine overnight.
It terms of the conversion itself it was really pretty easy. Keep in mind that I'm not a very handy guy so if it was easy for me it should be extremely simple for you. (While I can do simple bike maintenance like installing a cassette, chain, bar and/or stem I struggle with more complicated tasks like, for example, adjusting the front derailleur.) I used the
Hutchinson Fusion Road Tubeless tire (which is, to my knowledge, pretty much the only option currently available) and
Stans valve stems and sealant.
Since my Mavic Ksyrium ES rims don't have internal spoke holes, all I really needed to do was remove some of the excess rubber around the valve stem (so the tire bead could engage the rim hook), screw the valve stem in place and mount the tire. The only sorta tricky part was inflating the tire for the first time. I wasn't able to get enough air into the tire to seat the tire's bead so had to remove the valve core in order to inflate the tire. Of course, with no valve core I lost all of the air as soon as I removed the head of my floor pump. However, the bead stayed seated so I was able to replace the valve core and re-inflate without a problem. Since I didn't have a way to get the Stans into the tire via the valve stem (I need to buy some small diameter plastic tubing) I had to unseat a section of tire and pour the Stans directly into the tire. Again, I was able to re-inflate with the floor pump as most of the bead was still seated.
I'm curious to see how road tubeless works out. I've been running a tubeless setup on my mountain bike for the past 3+ years and have yet to experience a flat tire (that's not to say I haven't punctured, just that I've never had a puncture that didn't seal). If the same proves true on the road bike I'll be very, very happy.
As far as weight is concerned I'm guessing the front wheel is the same, if not slightly heavier, than before - mainly due to the sealant. In my mind this is a small price to pay for the convenience of eliminating flat tires from my road riding.
I should have my rear tire converted in the next day or two and will post an update after a few weeks of riding. If anybody has any personal experience with road tubeless I'd be interested to hear what you think.
UPDATE: I just finished converting my rear wheel to tubeless and it was much easier the 2nd time. Earlier in the evening I rode over to Revolution (about 21 miles round-trip from my house) to pick up some more valve stems and a 2 oz bottle of Stans. I ran about 95 PSI in the tubeless front tire and it rode great. It also felt different, though I'm at a loss to describe what the difference is. More lively? That sounds too cliche. A bit squirrely? Maybe, but that makes it sound like the wheel was hard to control and it wasn't. Who knows - I'll try and get out for another ride tomorrow now that both wheels are done and see if I notice any changes. Oh, and I should report that I didn't have any flats - front (tubeless) or rear (tube).
