The upright posture, chainstay length, and low center of gravity were meant for these kinds of circumstances. If you are planning a long bike tour with a significant load, the 520 has the right geometry for a comfortable ride. Not to mention the lifetime warranty provided by Trek that ensures you can get your bike checked by experts whenever it develops a malfunction. The advantage here is that these parts are relatively inexpensive and easy to replace. Generally, the 520 uses Shimano for most of its components. It doesn’t get better than this when it comes to frame stiffness on a touring bike. This helps to boost the lateral frame stiffness, increasing the bike’s stability with both front and rear loads. These cable-operated brakes utilize a special design that pulls the two brake pads simultaneously, providing a breaking performance close to hydraulic brakes system.Īnother notable change on the 520 that we liked is the larger diameter downtube. The brakes have also been upgraded to TRP Spyre-C calipers. While the majority of users of the old models chose to swap in a 11-36t cassette to attain a sub-20” climbing gear, this new model comes with one as standard. What impressed us about this bike is that the gear ratios have been improved. The Trek 520 is a functional touring bike with improved features that will serve you well on long-distance rides. The trek 520 weighs around 13kg itself and with the rack weight of 38 kg, the rider technically has to be under 74kg to meet this bikes requirement. The 48×11 top gear is built for powering down hills while the Alivio rear derailleur and Sora gear lever pairing work nicely together. The manufacturer has used a saucer-sized 36t sprocket that delivers a low bottom gear. We also liked the 48/36/26t Alivio mountain bike chainset, which comes with a tiny 26t internal chainring instead of a Shimano 105 road bike 50/39/30. It ensures that the quick release wheel is perfectly aligned in the fork, as is the case in a thru-axle system. This has the dropout looping all the way around the skewer to make sure that the wheel won’t fall out without removing the skewer. The grounds for this move, I believe, could be since Deore has currently moved on to 10-speed, there are no Shimano STI shifters that will pair with the 10-speed Deodre drivetrain parts.Īnother new feature on the bike’s fork is the trek thru-skew secure skewer system. However, a controversial feature on the this model is the step down from the Shimano Deodre gears to Alivio. The bike maintains the usual Chromoly frame, with the break from tradition being an aluminum alloy fork as opposed to the previously used steel forks. The Trek 520 frame features five different sizes of frames that include 48, 51, 54, 57 and 60 cm to accommodate a wider range of body sizes.
