Total Tech hubs are both RHD and LHD compatible through a SDS (switch drive system) driver. The Tech V2 rear hub uses a fully CNC machined alloy hub shell with low profile, recessed spoke flanges for great strength and low weight. The female axle is heat treated chromoly and uses 2x 17mm hex nuts for a neat and safe look, these hex bolts also feature a 6mm allen broach for multiple tool fittings. The Tech rear hubs use the reputable, tried and tested SDS switch driver system which allows the user the option to switch the hub to left hand or right hand drive in minutes with simple tools. This SDS system features 4 independently sprung pawls and runs on hard wearing, low maintenance polymer bushes, the hub shell uses 2 high quality Japanese sealed cartridge bearings with CNC machining alloy cones for smooth and long lasting performance. This hub comes set up as RHD as standard - We can set up for LHD before shipping - just specify in the special instructions. ###section### Product Specs HUB TYPE: Cassette AXLE: 14mm Male DRIVER: 9t SPOKE HOLES: 36h WEIGHT: 468g / 17.10oz
