Bike Knack is an Australian distributor of Gates Carbon Drive parts to individuals and dealers via our online Shop. For those who may be uncertain about the choice of product, Dave can provide advice on choosing a system that will meet your needs, help with changes in gear ratios or assist you to upgrade from CDC Mudport to CDX Centertrack. The newer CDX Centertrack system allows for easier belt alignment and lower belt tension, giving a longer bearing life and improving performance on less rigid frames. CDX Centertrack Blue and Black belts are available in 108- to 174-tooth lengths.
Gates Carbon Drive CDX Front Sprockets (22- to 70-tooth) mount on standard 130 mm BCD 5-arm or 104 mm BCD 4-arm crank spiders, as well as Bosch or Pinion splines. CDX Rear Sprockets can be fitted to Rohloff, Nexus, Alfine, Nuvinci, 9-spline, Surefit 3-lobe and thread-on (freewheel and fixed) configurations. CDX Cranksets are available for manual orDi2 shifting. Tandem bikes can use a CDX Tandem Belt and 66, 69 or 74-tooth CDX Tandem Sprockets.

Purchase Gates Products
Gates Carbon Drive belt-drive bicycles require a specialised frame. Unlike with a chain, it is not possible to open and rejoin a belt around the chainstay for installation. Instead, to install a belt, the frame must be opened. Although some bike manufacturers manufacture frames for Gates Carbon Drive, the available range is small. However, if a suitable frame cannot be purchased, belt-drive conversion of an existing frame may be an option.
Some road bike or hardtail mountain bike frames allow removal of a section of the seatstay and replacement with a custom splitter matched to the stay diameter. A frame jig is essential to stabilize the frame during cutting and installation of the splitter. After the splitter is in place, installation of the front and rear cogs can proceed, followed by belt installation and tensioning.
Bike Knack offers conversion of frames for Gates Carbon Drive by installation of custom-made splitters. Frame materials can be steel, alloy or titanium. Both internally geared hubs and single-speed systems are suitable. However, the frame will need a sliding rear dropout or eccentric bottom bracket to allow belt tensioning. Unfortunately, not all bike frames are suitable for belt drive conversion. For example, ovalized or very highly tapered seat stays are unsuitable. If you would like to confirm the suitability of your frame, email Dave or phone him on 0437 017022.
Our standard price for frame conversion is lower than that typically charged by frame builders. Shipping costs within Australia vary with frame size and weight, but can be calculated here. If you already own a suitable frame, frame splitting can offer a price-competitive entry point to belt-drive use. We can also supply your choice of belt and front and rear sprockets. A full range of Gates products is available in our Shop.
