OVERFAST Colnago Y1RS Upgrade Kit
The OVERFAST Colnago Y1RS Upgrade Kit is everything you need to customize and significantly reduce the weight of your Y1RS. This kit includes carbon fiber thru-axles, titanium pre-load system, carbon fiber battery cover, and gap kit.
The OVERFAST Carbon Fiber Thru-Axles are exceptionally lightweight thru-axles. These feature an aluminum threaded end with a carbon fiber body and weigh less than 30g for both front and rear axles. The head of the axle includes a titanium insert to improve durability as they are installed and removed from your bike.
The OVERFAST Colnago Y1RS Titanium Pre-Load System is designed to replace the OE pre-load system in Colnago Y1RS road bikes. It is precision machined from titanium and weighs about 40% less than the OE system used by Colnago. These are frame size specific.
The OVERFAST Colnago Y1RS Di2 Battery Holder is a carbon fiber battery holder for the downtube of the Colnago Y1RS. It uses a carbon fiber cover and composite body to reduce the weight of your Colnago Y1RS. It is available for Shimano and SRAM, where the SRAM version is only the cover and saves even more weight as it does not have a composite body. This battery holder is also available in forged and 3K designs.
The OVERFAST Colnago Y1RS Gap Kit is a three piece kit that is designed to improve the aesthetics of your Colnago Y1RS. While this kit is most often paired with the OVERFAST Colnago Y1RS Titanium Pre-Load System, it can be used on its own. The kit includes a seatpost cover, headset cover, and Di2 plug. The Seatpost cover provides extra protection against dirt and debris. The headset cover eliminates the gap in the headset left from the bayonet style fork. The Di2 plug helps route the Di2 wire to the rear derailleur.
