They have the same casing but the Barlow Pass has slightly thicker tread. Snoqualmie Pass has thinner tread. I've currently have a Barlow Pass mounted on the front and a Snoqualmie Pass on the rear. Both great tyres. Both fast on roads and gravel. In a group ride or climbing, the width doesn't cost you much, if any speed. Once you get over 40km/h there is a penalty, the 38mm on the front costs me about 5km/h on my fastest local descent, compared to my roadie with aero wheels: 58km/h vs 63km/h average speed over 4km.fattywilliams wrote: ↑Sun Mar 29, 2020 4:42 pmhow can it be lighter than the Barlow pass given that they are 44mm and the Barlow only 38?
For my frame geometry, the 44mm on the front slows the steering down a bit too much, so I prefer the 38mm size.
I have 2600km on the BP since November 2019, and no punctures. I have 5000km on the SP, and no punctures. I put a 3mm wide stick through the other SP by riding over a branch at the 3500km mark. The hole was too big for the dynaplug, and I had to put a tube in. I've also tried the 35mm Extra Light, 32mm Extra Light, and 28mm Standard Rene Herse tyres on this bike and two other bikes. All roll very well. The 28's lasted 7000km before they were very thin and puncturing every couple of weeks. I've since switched to Vittoria Corsa Tubeless for my pure road bike, but will continue to use Rene Herse for anything 35mm or larger.
