If you’re committed to that size, you want to know in advance that it’ll work. The road lead past the ghost town … From the puncture tests, it appears obvious that Compass, in their quest for a supple tire, doesn't use an anti-puncture belt under the tread and uses a very easy to puncture casing. I was interested in the move to wider tires and thought that going from 25s up to 32s would be a good test of their reported benefits: a smoother ride, greater resistance to pinch flats and no loss in speed compared to “racier” tires. The wide tire revolution is catching on in Europe as well, so I think there is a market…. https://janheine.wordpress.com/2012/11/06/ride-the-bike-you-have/, http://bikingtoplay.blogspot.com/2014/12/trek-620-650b-conversion.html, https://janheine.wordpress.com/2014/01/01/tires-how-wide-is-too-wide/, https://janheine.wordpress.com/2012/01/30/the-downsides-of-wide-tires/. Most people that asked me to test this tire really wanted to know how it performs in the rolling resistance tests. The 700x35c rated Bon Jon Pass with the regular casing has a specified weight of 355 grams. I've opted to test the Bon Jon Pass with the regular tan colored casing. At the moment I am thinking of going for the Compass Loup Loup Pass EL (650B x 38 mm) or even Grand Bois Cyprès EL (650B x 32 mm), but would I benefit from Compass Babyshoe Pass (650B x 42 mm) tires with my riding? Complete bike from Craigslist: $300 So when Compass came out with their 26"x2.3" Rat Trap Pass tires I was excited to try them out on my Surly Disc Trucker. Thank you for doing something so nice and positive for the rest of us humankind. This video is about Compass Bicycle Tires a Year in Review – part 2. All rolling resistance tests are performed on our rolling resistance test machine. 650bx42 to 50psi 4. Dash bike- dapu M65X Updated: 2 months ago ... spoked the wheels with thick 13 gauge wire and chose extra wide 2.4″ tires for comfort, traction, and stability. In our lab tests, the Bon Jon Pass performs well although maybe not as good as expected from such a thin and light tire. It seems like I’d spend nearly half of that on wheels and tires, which doesn’t leave much room for a modern groupset. On my Nordavinden with 622x32mm Compass tires, inflated to around 3x the pressure of my Trucker, it loses pressure much more rapidly. Although I've placed the 35 mm wide Bon Jon Pass in the touring bike category, it has become obvious to me that this is more of a big road bike tire than a true touring bike tire after taking these measurements. 200 easy strokes from flat to about 40psi. Plus my experience is that under 25PSI on 559x55mm tires is basically ‘un-flattable’. Changing to 650B will cost you for new wheels and probably new, longer-reach brakes. BUY NOW. wider is better)? Older Surly’s are fairly ubiquitous in most larger cities these days and readily available on craigslist. Of course with fatty tires at lower pressure you are free to use a pump with more volume per stroke, but in this test I “used” the same pump across the board, figuring 200cc of volume per stroke (somewhat WAG of frame pump volume). My kids would love to be able to verify any submitted data…. By amount, I mean number of molecules of air. Something new for the Specialized AWOL x Poler: Swapped 29″ x 1.9″ Specialized Ground Control tires for the 700c x 44mm Compass Gravel Tires for raw speed with wide supple comfort. At the end of the stroke, there is some residual air in the pump, essentially whatever space is between the plunger and the tire. Long reach brakes: $55 I’m sure many readers are better at physics than I am, so please correct me if I’m wrong. I am going to follow your advice most of the way, however. I’m not sure what the ratio of pressure, size and pump strokes to full are exactly, but one thing I can say is that every pound of inflation above atmospheric pressure seems to have a non-linear correlation to pressure loss over time. Schwalbe SV14A tube For the same comfort level, you can run the Bon Jon Pass at a higher air pressure which basically means rolling resistance will be slightly better (at the same comfort level) than the tests indicate. The reality though is that the Bon Jon Pass isn't a true touring bike tire as the tread and sidewalls are thin and very easy to puncture. / 5 “These Tires Expand Your Riding Universe” declared Fred Matheny at Roadbikerider.com after riding the 700C x 38 mm Barlow Pass Extralight tires. Those might not be “real” numbers, but they were all calculated the same way so at least they may be useful for comparison. I was just deciding between two of my slightly older (late ’70s) Treks for exactly that conversion, although now I’m wondering if they can handle the soon-to-be-available 26″ X 2.2″ Rat Trap Pass tires. For example, my brake’s QR opens just enough to clear 25 mm tires on narrow Open Pro rims, but it could clear wider tires if I used wider rims. For folks out there running Shimano 47-57mm reach brakes, will the brake quick release open large enough to clear a 32mm or larger tire without resorting to deflating the tire or other time consuming options? It seems like if you want to experience the full BQ Holy Trinity (supple tires, flexible frame, low trail), on a budget, your best bet is a old sport touring frame and then a 650B conversion. Cheap wheels off ebay: $140 Most new frames are at 130 (“road”) or 135 (“mountain” or “touring”) mm. When we compare this to the fastest rolling tire in the touring bike category, the difference is immense as the Schwalbe Marathon Almotion (read review) scores 86 points for the tread and 5 points for the sidewalls. “As good as the standard Stampede Pass versions are, the extralights are in a completely different league. Rene Herse Tires. I am waiting for the new 700-35 and hope to ride them for PBP, That would be like determining how many licks it takes to get to the center of a Charms Blow Pop. I just wish the 650B tires didn’t look so goofy with my 25″ frame. An important part of any tire is the total tire thickness of both the tread and sidewalls as it gives us a good indication of how it's built and what the design choices were. There are also some brake levers with built-in QRs that allow the brakes to open even wider. That would give indicate that You would need 1.8 times the number of pump strokes to inflate the 38’s to .6 times the pressure of the 23’s and the 42’s at half the pressure 1.75 times the number of pump strokes. Lezyne Swivel Drive HP pump (no longer made – similar to the Micro Floor Drive HP but about 3cm shorter, and easily fits in handlebar bag) So unless the frame was designed for wider-than-usual tires (e.g., a cyclocross bike, or some older frames), 38 mm will not fit. Panaracer makes the tires for Compass so construction is solid. For just a touch more perspective, a 5 rating would be a fantastic, fast-rolling gravel race tire. 2. Or would you recommend going for the widest tire your bike will fit (i.e. And they don’t really cost any more than other brands of high-performance tires. Compass also sells this tire with an extra light casing that saves 50 grams of weight but has an even higher price tag. James – I’ve been continuing my voyage through the wide-rubber-specialists Compass … Old favourites like the Zefal HPX were designed to inflate narrow tyres to high pressures. Tread Depth. In the sidewall puncture test, it performs awfully as well with a score of just 3 points (basically the lowest possible score). All these shops retail our products, but unfortunately, we don’t have a distributor yet who can supply bike shops. My sample comes in a bit lighter at 346 grams which is always a nice bonus when buying an expensive tire. Rene Herse tires roll fast and absorb vibrations. Good luck. Can you give me a rough breakdown on how much you paid for different pieces to get to a $650 investment? I’ll probably put those same Barlow Pass tires on it. Price: $9.99 Orienteering Compass - Hiking Backpacking Compass - Advanced Scout Compass for Camping and Navigation - Boy Scout Compass for Kids - Professional Field Compass … This bike with these tires is a true all road go anywhere bike. I purchased 2, one for me and one for my wife and they are great for riding around town but not much … For those doing occasional forays onto dirt road connectors, look to the lower end of this scale. Check our The Test I’m foregoing the 650B wheels and thus the widest Compass tires for now, but this seems like a decent compromise and an excellent price. The full review is here. I should also say that my brakes are set up so that the pads start touching the rims when the levers are halfway actuated (not a “hair trigger” setup) so my setup is already biased towards more tire clearance from the brake pads. Still, it nice to hear from customers that they enjoy the product. Most road bikes today have clearance for 25 mm tires, some up to 32 mm, but rather few beyond that.
