The Tetrarack M2L by Topeak is a fantastic rear rack system designed specifically for MTB bikes. It can be easily attached to both full suspension seatstays and rigid bikes, even if they don't have rack eyelets. One of the standout features of this rack is its innovative top plate. It can be adjusted on a convex track, ensuring that it stays level to the ground no matter the angle of the seat stays. This makes it incredibly versatile and perfect for any bike setup. Topeak has also incorporated their QuickTrack system into this rack, allowing their TrunkBags to be easily attached and removed. All it takes is a simple push of a button. The TetraRack M2L also features a hook and loop strap mounting system. This system ensures that the load on the rack stays stable, even on rough terrain. Additionally, it allows the rack to be mounted on a wide range of bikes. Please note that the TetraRack M2L is not recommended for use with carbon forks and seat stays. It is compatible with RackTime® Snapit system bags. Overall, the Tetrarack M2L by Topeak is a reliable and versatile choice for anyone looking to add a rear rack to their MTB bike.
