At Compass, we see little point in replicating what you already can buy from others. When we made our first knobby tires, we wanted true dual-purpose tires. Could the new knobbies match the on-pavement of good road tires, yet grip as well in mud as true cyclocross tires. Impossible? You’ll never find out unless you try…
After a few seasons of cyclocross, there is no doubt that the Compass Steilacoom (700C x 38 mm) and Pumpkin Ridge (650B x 42 mm) offer plenty of grip and shed mud well – as you’d expect from their widely spaced knobs.
How about their on-pavement performance? I’ll let others speak on that. Matt Surch, the well-known Canadian gravel racer, wrote: “I don’t understand how the tread rolls so fast and quiet… these are wild!”
When BQ tester Mark tried them, he wrote: “Once the wind drowned out the tire roar at high speed, I was thinking about how unremarkable the Steilacoom tires had rolled on the paved descent. I had pretty much forgotten that I was riding on knobbies.” Yet he was glad to have them when a road closure detoured us via a muddy trail (above).
And now Mike Stead tested a set of Steilacooms for www.road.cc. Among other adventures, he set two Strava records on these tires. One was for a gravel descent. His comment: “I wasn’t even pushing that hard. […] The Steilacooms make you a better, faster descender than you deserve to be.”
The second KOM surprised not just him, but us as well: He set a new record for a flat-out 60-second sprint – on pavement. He wrote: “Averaging 45 kph, the Steilacooms made an awesome high-pitched noise as I fanged along the straight. Just to prove it wasn’t a fluke, I went back the next week and recorded exactly the same time to the second.”
Mike’s time on the Steilacooms was two seconds faster than the previous KOM record, which he had set on our Barlow Pass tires. Does that mean our knobbies are faster than our road tires? Not necessarily – there are too many variables – but it shows that they certainly aren’t much slower. And that is remarkable, considering that our road tires are among the fastest in the world.
In a future post, I’ll explain how we created a knobby that doesn’t ride like a knobby… until you hit mud or snow, when it behaves exactly like a knobby. But don’t take our word for it – read Mike Stead’s review.
