Sram XX Transmission 1987 AXS groupset

The Sram 1987 Eagle Transmission 1987 Collection derailleur and drivetrain group.

The Transmission rear derailleurs are only suitable for frames with UDH specification and an interface without a derailleur hanger; the rear derailleur cannot be fitted to frames with conventional derailleur hangers.

This limited edition groupset offers a unique combination of T-Type Ecosystem components, of which SRAM is particularly proud, all in an exclusive silver finish. This is the 1987 Collection. A dream come true.

The Eagle Transmission 1987 Collection is a strictly limited special edition that combines the best of the modern SRAM T-Type Ecosystem in an exclusive silver finish. The selection of components is not only technically top-notch but also makes a clear visual statement. Based on almost four decades of development in the field of high-quality MTB drivetrains, the Eagle Transmission remains true to its proven concept: precise shifting, maximum durability and uncompromising performance – now in an edition that stylishly bridges the past and the present. The 1987 Collection is more than just a drivetrain – it is a tribute to innovation, design and a passion for cycling.

SRAM 1987 Eagle AXS Transmission Rear Derailleur:

The AXS 1987 rear derailleur is the epitome of performance, durability and style, perfectly combining lightness and robustness. This has been achieved by combining the robust cage of the SRAM XX rear derailleur with the lightweight body of the XX SL rear derailleur. The limited-edition silver colour scheme is paired with Full-Mount architecture to deliver a rear derailleur that shifts perfectly with every shift.

UDH, Universal Derailleur Hanger, Interface:

UDH stands for Universal Derailleur Hanger and is a standard for derailleur hangers that unifies the multitude of existing standards. The aim of UDH is to reduce the complexity of finding replacement derailleur hangers for bicycles by using a uniform design. Sram UDH rear derailleurs are mounted directly onto the frame without a derailleur hanger. This guarantees maximum torsional stiffness and always ensures the perfect position relative to the cassette. Of course, it is essential that your frame has a UDH derailleur hanger or the UDH interface.

Shifter: SRAM 1987 Egale AXS Transmission Pod Controller:

Two SRAM AXS Pod Ultimate Controllers complete the kit, offering you a clean cockpit and the freedom to customise the controls for your left and right hands. The package includes silver Infinity clamps to complement the rest of the system.

Crankset Sram 1987 Eagle AXS Transmission DUB WidePowermeter:

Take the most advanced aluminium crankset SRAM has ever built, the X0 T-Type, and combine it with SRAM’s most accurate and integrated power meter. The dual-sided power measurement system calculates total power output, is unobtrusive, lightweight and has unbeatable battery life. This groundbreaking crankset features an all-aluminium design and a perfectly balanced ratio of stiffness to weight. Crank arm length: 170 mm.

Sram XX Eagle Transmission chainring:

The XX Eagle Transmission chainrings with T-Type technology are perfectly matched to MTB flat-top chains and are only compatible with these.

SRAM XX Eagle Transmission cassette:

The XX Eagle Transmission T-Type cassette is one of the main reasons why Eagle Transmission offers the best shifting performance under load. Thanks to its X-SYNC design, the harder you pedal, the better it shifts. Literally. The XX Eagle Transmission cassette and rear derailleur are designed as integrated and interdependent drivetrain components that mesh directly with one another, ensuring perfect alignment on every bike. The 52-tooth sprocket has a massive gear range of 520 per cent and offers improved gear spacing with 44 and 38 teeth in the lower range compared to the Eagle drivetrain’s 10-52 cassette. It lasts significantly longer and offers greater precision, as it features less extreme chain angles across the entire gear ratio range. Thanks to the clearly marked setup sprocket, installation is child’s play and absolutely secure. Uses hardened tool steel for the groupset’s X-DOME construction. The 38- and 44-tooth sprockets, made from stamped steel, are attached to the lighter aluminium sprocket of the 1st gear. Carrier sprocket

Sram XD Driver Body XD

is a new freehub design that allows the use of a 10-tooth ring and offers an improved engagement surface with the cassette. Only compatible with rear wheels featuring the special XD freehub body

Chain Sram PC 1987 Eagle Transmission Flattop :

The T-Type chain from the 1987 Collection features hollow-shaped chain links, hollow pins and a hard chrome coating that takes the strength-to-weight ratio to an unprecedented level. The subtle details bear the signature of SRAM founder Stan Day as well as the group’s unique serial number.
