The Pulse Cassette hub is groundbreaking to say the least, a principal in BMX cassette hubs and a pioneer in universal hub design. Since conception the pawls have been improved and the driver function has been tweaked to perfection. The Pulse cassette hub features éclats own patented switch drive system, which enables the hub to run both RSD and LSD with the same driver and the same hub shell.
For 2015 the hub now features a 14mm bolt female axle for improved strength making it the strongest cassette hub on the market.
