Cell Cycling recommend the use of a 6mm Punch for cutting an accurate hole in your hood or handlebar tapeCurrent software allows only two buttons to connect to the BlakBox transceiver via two USB-C ports. That said, the software currently only supports a single shifter. However, enhanced firmware in the pipeline (coming 1st quarter of 2021) will allow nearly unlimited buttons and shifters to connect. It can be mounted under the stem or wrapped under bar tape anywhere, with its small size making it a viable option for time trial bars too. The brand say they already have customers in the hand cycle market testing the electronic shifter with adaptive buttons for chin control.

The Cell BIT is a 1.5g aluminium button, smaller than a quarter. Its size is what makes it such a versatile upgrade; mount it almost anywhere on the bar, including the hoods, tops, drops, or even the end of a TT bar.
