The platform is designed to give riders the freedom to find their best possible position with a huge range of independent adjustments.

The Ergo armrest is an integral part of the overall adjustability scheme. The dual-offset design gives a precise adjustment range. This, along with the evenly curved shape, allows it to work well for the majority of riders. There are 80 distinct positions options achievable just by moving the armrest. Combine that with risers and you got 1440 possible configurations. It is also possible to adjust the extension width and tilt easily.

The 4525c extensions have a first section at 45° and the grip at 25°. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position. The 4525c offer a 7.5mm lateral shift per side. This allows the rider to get their hands narrower or wider without tilting the extensions so much that they touch the shifters. The extension length and rotation can be easily adjusted using the top bolt.
