![]() ![]() SRAM XD is the newer of the two main standards. ![]() This will change with Shimano’s new Micro Spline, which will likely gain in popularity over the next couple of years. There are more, but a vast majority of our audience will be using one of these two. With mountain bikes, we have two main cassette freehub body standards. Sunrace CSMX80 11-50T Cassette 455%Ī chainring swap has its own standards, but once you start messing with cassettes, there are other configurations to contend with.As an example, a 2×10 drivetrain with an 11-36T cassette combined with 36/24T chainrings on the crankset has a gear range of 491%. This is a big difference from the near 500% range provided by a standard 2×10 drivetrain. To work out the range of 1x drivetrain, it’s as simple as calculating the range of a cassette: divide the largest cog by the smallest and then multiply this by one hundred (42 ÷ 11 = 3.82 x 100 = 382%). If you’re reading this, you’re probably familiar with SRAM’s Eagle 1×12, which touts a wide 500% range, or the new Shimano XTR, which has 511%. That brings us to the second issue people face when moving from multiple rings to just one in the front-the limited range of gears available with a standard 11-42T cassette. There’s one problem with moving to a small chainring to compensate for the load: the loss of the high end gears, which in the field translates to spinning out at relatively slow speeds. First impressions are good and we’ll be sure to update this a few hundred miles down the road. We recently installed the SWITCH system, but haven’t had a lot of time to test it. Rings are available in 28-36T, round or oval, for $40. SWITCH spiders are available for Cannondale, e13, Hope, SRAM DM, and Cinch standards, in 0mm, 3mm (BOOST), and 6mm offsets for $23. Similar to CAMO, OneUp’s SWITCH was developed to reduce the cost of replacement chainrings, increase compatibility with new offsets, and to make the process of changing your chainring much quicker and easier. Here are a few, ordered roughly by popularity: Each crankset manufacturer uses its own particular standard to allow chainrings or spiders to be bolted directly to the crank assembly. Direct mounts typically allow you to go as low as 26 teeth, which might be excessive for some situations, but, when compensating for heavy loads and large plus tires on steep climbs, it’s not beyond reason.įor the uninitiated, direct mount is not a standard, unfortunately. The simplest solution is to switch to a smaller chainring via a direct mount crankset. And for most of us mortals, this will require a front chainring that has fewer than 32 teeth when paired with the standard 11-42T cassette, especially when using plus-size tires. For some of us, it’s around 18-20 gear inches. What’s a proper bikepacking granny gear? Well, that’s a personal preference, often governed by your own physiology and the weight of your gear, and sometimes one that takes a bit of trial and error to figure out. This often means it lacks a proper granny gear. Most of the time, out of the box drivetrains have a gear range that wasn’t designed for pedaling a bike with the added weight of camping gear and supplies, and as such, is geared too high for bikepacking. ![]() The first and most obvious is gearing that’s too high. On the other hand, when transitioning to a 1×11 drivetrain, bikepackers face two issues. In addition, eliminating the front mech often frees up space needed to accomodate plus tires. Folks often justify the shift with the fact that a 1x system is simpler, which minimizes cables and generally cleans up the cockpit and the frame triangle. But, at this point, a solid majority of mountain bikers and many bikepackers have switched to a 1x drivetrain. There are still quite a few holdouts using 2×10 MTB drivetrains-which, for the record, are perfectly fine-and even some folks sticking by 3×9. ![]()
