anyone have initial ride impressions and width info after they have been inflated a bit? i am trying to decide between these and the RTP's for a build i am working on. any thoughts would be greatly appreciated.

The Hetres have been great on everything, with grip on all surfaces in all weathers, no punctures, little wear, and decent ride quality. The Somas are noticeably lighter and faster, but grip is dubious, they're almost done and they have some weird handling traits; they *will not* climb onto painted lines even in the dry, bouncing off instead. They also bounce or are steered off any vaguely linear road features, imperfections or repairs, not exactly ideal if you're in a paceline, or even just trying to ride up a kerb cut. :-(

I think that SBH and fenders under Paul Racer brakes is too tight. Its already pushing with Hetres and full fenders.

Thanks Fred; looks like I'm going to have to order a pile of stuff from Compass. (Rolls eyes.) Pity the exchange rate is about the worst it's been for 35 years or so. <sigh>

Anyone use these tires on a Stag yet?

Too tight I think.
What are the odds on combining these + Paul Racers + Fenders?

Especially w/r/t single track. That really surprises me.
Fred can you give a bit more on the SBH vs Thunder Burt specifically? I'm building a bike for the type of riding you describe and would appreciate hearing more.

Fred, can you comment on the relative merits of the RoRo versus the RaRa? Where I usually ride it's mainly sandstone country, so hardpack with a bit of loose stuff, and occasional sand patches, no mud or soft soil. What counts most here is directional stability on sand and cornering grip on the loose stuff, plus low rolling resistance. Just about anything grips fine on the hardpack.
Later,

Sorry I'm a bit late on this thread. I was planning to try the Switchbacks on my commuter bike, which sees a combination of smooth and rough pavement, a mile of diamond plate bridgeway, and a bit of hard dirt path, slightly more on weekends. But 90% would be straight, relatively smooth pavement. Fred, is it your opinion that the Switchbacks are not the optimal tire for this application? (Flat resistance is not an issue for me in making a decision. Knock wood.)

One thing that although the 48mm tires will fit, Jan mention that these tires will swell with use up to 51mm
Jan measures tires differently than most people, with his "hot dog in a hallway" caliper technique.
I'm riding the oldest most stretched Switchback Hills, one of mine is 48.5mm and the other is almost 50mm, on modern MTB rims with a 23mm inside width. On normal rim brake rims with a 18mm inside width the larger one would be true to size.

Sbh will fit with Raids or the Compass repro and fenders if the bike is designed appropriately.
I sqeezed a pair onto my Allroad, and they just fit between the fork crown and chainstays.
However, a ride with Boulder Bicycle head Mike Kone led to a long chat about the design needs of a machine to take advantage of the SBH tires (with fenders) and something frisky in the 2.1" range without. We'll see where it goes.
I ordinarily just roll away from Mike on descents. He was on my bike, and I was on one of the (excellent) shop bikes with BSP EL's, and I was drifting his bike around the corners--and still losing ground--on one of his pet unpaved-road sections.
The effect was not subtle off-pavement--they were comfortable, still fast, and stuck to the road better. They are overkill for typical county-road conditions, and lose a step out of the saddle, but for a dedicated drop-bar off-pavement machine, they are a better solution.
Best,

On gravel, you really should have at least 20 mm, better 25 mm, between tire and fender. Any less, and you'll hear a lot of small stones rolling between tire and fender, and you always risk the dreaded fender collapse that can send you over the bars.
