First day of Sea Otter and we’ve already found a new hub standard. Sort of. Marin took the wraps off the new 2017 Pine Mountain 1 which slots in between the current Pine Mountain 1 and 2, with the 2016 PM1 becoming just the Pine Mountain going forward.
While the addition of a plus bike with a suspension fork and a 1×11 drivetrain for just $1299 is notable, what really caught our attention was the mention of “Boost 141x9mm open dropouts.” This was the first we’d heard of it, so it was straight over to Marin to learn more…
After a quick run through the numbers, you realize that 141mm is 7mm less than 148, just like 135mm was 7mm less than the 142mm thru axles. That’s exactly what is going on here. The new 141x9mm hubs will be the QR equivalent of Boost 148 thru axle bikes which has a few advantages. The biggest seems to be from an OEM perspective (and also to the benefit of the consumer) in that it allows companies like Marin to build a plus bike around the Boost spacing and chainline for proper tire clearance with a less expensive hub and ultimately frame. That means bikes like the new Pine Mountain 1 benefit from a stronger rear wheel and better frame design without resorting to the more expensive thru axle frames.
It also means for many companies like Industry 9 and Stans, they can offer Boost 148 TA and 141mm QR compatible wheels with the same rear hub, just different end caps. So far we’ve confirmed with both I9 and Stan’s that their Boost wheels will be compatible with 141mm QR frames by using their standard QR end caps. We also heard rumors that while Marin is the first to show a bike with 141×9 dropouts, most of the big brands have already signed on and have bikes in the works with the new size in the near future. This will likely bring back the days where the entry level bikes will come with QR wheels and dropouts to save money, but will have dropout chips that could be upgraded to thru axle in the future along with the wheels.
Frame details include a double butted chromoly tube set, full rack and fender mounts, and even frame back mounts under the top tube.
Regardless of your opinion on the dropouts, the Pine Mountain 1 looks like a great bike that will be speced with the new Shimano SLX 1×11 (11-42) drivetrain using Marin’s own crank with Boost chainline. Equipped with a RockShox Recon Silver RL Boost fork with 120mm of travel, the wheels are 40mm inner width, tubeless ready, and come wrapped in Schwalbe Nobby Nic 27.5 x 3.0″ tires. Due to the fact that the original Pine Mountain 1 (now Pine Mountain) was such a big hit, the new PM1 is an early 2017 release that will be available later Summer for $1299.
Not to be overlooked, Marin also has a killer deal on the gravel/all road/commuter side with the new Nicasio. Also using a double butted chromoly frame, the Nicasio brings a drop bar, disc brake 2×8 bike to $769.99. Fitting up to 40mm tires (comes stock with 30mm), the bike uses 135mm rear, 100mm front QR dropouts with a Shimano Claris drivetrain and will be available late summer.
