I've been riding Conti's for about 10 years now; clinchers with tubes. I got occasional flats but, and it may be luck, haven't had a flat now for almost 3 years and 7K miles. It may be that going to wider tires (I'm now on 30's) and lower tire pressures (now at 60 & 65) result in fewer flats? Conti's have a reputation for being hard to mount. This was true on my 21mm internal alloy wheels. But, I am able to mount the 30's on Vision carbon wheels using only my hands. So, it seems the right combination of wheel and tire make a difference. I got about 3K on size 25mm but am getting more than that since upsizing. They roll nicely on the Vision wheels with Silca TPU tubes; low rolling resistance and reliable combo.
I bought the Vision wheels to replace the hookless alloy bricks that came with my Defy. I have no other point of comparison but I love these wheels. Light enough, true, roll nicely. Paired with GP5000 30's and Silca TPU tubes. The 23mm internal width allows the 30's to measure out at 31mm. Very easy to mount the tires (yeah, I know, GP5000's!) by hand; no tools or levers required. I get a nice efficient ride, great cornering, and the bike fairly jumps underneath me when powering up hills. I come close to the rule of 105 with the 30's on these wheels. Great combo IMO.
The ENVE tubeless valve stem is designed with a rectangular foot allowing it to fit securely in the valley of the rim giving a secure seal and removing any chance for the valve stem failures of the conically shaped stems. Using an ENVE stem with a new tubeless tire will allow you to easily inflate and seat the tire with a floor pump. When I first ordered these stems, they got lost in the mail somehow, and I called Bikee Tires Direct and the resent the order right away. Thank you
I followed the instructions exactly, but still could not get the wrap to stick without bubbles forming. The quality of the material is excellent, and I have no doubt it will protect my paint, but in retrospect I should have used an experienced professional to apply the wrap. I only put on a few pieces, and will leave them on since the protection is the main reason for using this. If you are skilled at placing decals, then this is a great product. If not, it still does a great job, but it will not be invisible - you will see the bubbles. This is not to ding the product itself, it's just that it is difficult to apply perfectly, especially the larger pieces.
