I've only been using the B-lines for the past few weeks, so I can't speak to their durability. And, I've only had one flat in the last xx years (double-digits!) on any tire, so I'm not sure about their relative flat resistance. But, I have ridden them on the same bike over the same routes as with CdlVs, Nifty Swiftys, and Hetres. I think the B-line fits in a nice space between the CdlVs and Niftys. They are almost as easy to accelerate as the Niftys, while providing similar cush and handling as the CdlVs. These features are important to me, as I'm using them on the Quickbeam commuter. So, lots of stops and starts, crappy surfaces, and the need to be nimble in my urban area.
I found the Hetres to be slow in the starts, and the width (I'm guessing) made for slow handling. I only liked the Niftys pumped pretty high (~60-65 psi, and I've tried a lot of different ranges). But, this gave a harsh ride--although I did like how easy it was to climb with them when doing longer distance rides. The CdlVs provided a softer ride with quick enough handling for me. But, they were noticeably harder to accelerate and climbing was a little bit more of a slog. Sorry, I don't have any experience with the Hyper-Tex version of the SOMAs. One note: I don't think the B-lines will measure out to a true 38 mm. The CdlVs I've had for the past 2.5 years measured 35.5 mm. I think the B-lines will be similar. Next on my imaginary budget-less list: the new GB 584x36 tires, the Cypres, and the PMs. And now for the pics!: http://tinyurl.com/2ajarmb http://tinyurl.com/2d23ryl http://tinyurl.com/24tlw2v http://tinyurl.com/26ogncm Best, Lee On Nov 1, 7:38 pm, jsk <[email protected]> wrote: > Hey there, > > Is anyone riding the new Soma 650b tires?
