![]() ![]() The otherworldly terrain of Moab, Utah, served as the location for the launch of the Trail 429, which meant that there were plenty of chunky climbs and even chunkier descents on the menu for the day's ride - Mag 7 to the Portal Trail. Pivot did experiment with an aluminum mule that had the same amount of travel but some very extreme numbers, like a 62.5° head angle and a 530mm reach on a size XL, in order to see where the limits were, but ended up settling on the current numbers in order to have a bike that handle well going up and down, and was well suited to a wide range of riders. In short, all of those changes bring the Trail 429 right up to speed when it comes to modern trail bike geometry without getting too radical. The other number worth noting is the chainstay length – it's been reduced from 443mm down to 430mm. The 27.5+ version uses a 17mm lower headset cup to prevent the BB height from getting too low with the smaller wheels, but that cup is also included with the 29" version, where it can be used to slacken the head tube angle. The head angle hasn't changed quite as drastically, since Pivot wanted to preserve the bike's quick and lively handling, but it did drop from 67.5° down to 67.3° degrees. The seat tube angle has been steepened to go along with the longer reach, and it's now 74°, up from 72.8°. The Trail 429's reach numbers have increased significantly, and the size large now has a reach of 460mm, where the previous version measured in at only 423mm. According to Chris Cocalis, Pivot's founder, their frame tolerances are tight enough that they haven't had any issues with unwanted creaking, and they see PressFit as a better system for carbon frames, one that's closer to what's used for a headset, as opposed to bonding in a threaded sleeve, and then threading in cups with bearing pressed into them. Pivot have also stuck with a PressFit 92 bottom bracket - after all, they're the ones who originally developed the system. The brake, dropper, and derailleur housing are all routed internally through the front triangle, with the derailleur housing emerging on the underside of the downtube and running externally below the bottom bracket shell, while the rear brake line is routed safely on top of the chainstay. There's plenty of room for a large water bottle, even on the extra-small size, and even when a shock with a piggyback reservoir is installed. The cable routing has been updated, and the brake and derailleur housing now run through the front triangle. ![]()
