OVERFAST Colnago Y1RS Di2 Battery Holder
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.
