The Trek 820 is a multi-purpose mountain bike that may also be used as a hybrid. This bike has a robust steel frame, semi-slick tyres, a suspension fork, alloy wheels, Shimano 21-speed transmission, and rack mounts to name a few features.

The bike was not only developed for speed but also for comfort, including a Bontrager saddle, seatpost, and handlebars, which are a feature of most trek bicycles.

Rack Mount

The Trek 820 has a mount that can be used to attach a rack. During long journeys, especially while mountain biking, you can store supplies in the rack for when you get hungry. However, the attachment on the Trek 820 can be used for fenders, kickstands, lights, mudguards, or even a fitness tracker, depending on your preferences. The bike is built to handle the load on the rack, so you don’t have to worry about it.

Shimano drivetrain on the suspension fork

The front wheel of this bike includes a shock-absorbing fork that allows it to easily glide over obstacles. The Shimano drivetrain, which includes a Tourney version of the cassette, derailleurs, chain, and shifter, all contribute to the bike’s strength and stability while in motion. The drivetrain is ideal for riders who are new to off-road bicycling because it provides stability and support.

Trek Custom Steel Frame

This bike has a unique steel frame, which contributes to its longevity. This steel frame is a high-quality hand-carved stainless steel lug with fillet brazed tubing. Because of this characteristic, the Trek 820 is the greatest mountain bike in terms of durability and comfort. Steel also reinforces the frame, resulting in a more comfortable ride.
