Clean - Smooth - SImple
If you’ve bought a bicycle in the past 120 years, chances are it’s been powered by a chain. While the trusty bicycle chain has done every cyclist well, Gates wanted to not only improve cycling, but revolutionize it. So they created the Gates Carbon Drive.
Gates Carbon Drive belts use carbon fiber in a urethane body. The belts don’t rust, stretch or need oil, and last three times longer than a chain. Paired with Gates Carbon Drive sprockets, they provide the smooth ride cyclists want, without some of the downsides of the traditional bike chain. The Gates Carbon Drive system is stronger, quieter and requires less maintenance. It won’t leave any marks on your pants and you’ll never have to pull over to fix a dropped chain. Come to think of it, revolutionary might not even do it justice.
Gates Carbon Drive Parts
Bike Knack is proud to provide Gates Carbon Drive parts to individuals and dealers. We are also happy to provide detailed advice on choosing a system that will meet your needs. We can alter gear ratios or upgrade from CDC Mudport to CDX Centertrack. The CDX Centertrack system allows for easy belt alignment and lower belt tension, leading to longer bearing life and improving performance on less rigid frames. CDX Centertrack Blue, Black and now Red belts are available in 108- to 125-tooth lengths.
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 spline. CDX Rear Sprockets can be fitted to Rohloff, Nexus, Alfine, Nuvinci, Sram G8, Sram E-matic, 9-spline, 9-spline 6-bolt, Surefit 3-lobe and thread-on (freewheel and fixed) configurations. Gates also supplies CDX Cranksets for both manual and Di2 shifting. Tandem bikes can use a CDX Tandem Belt and 66, 69 or 74-tooth CDX Tandem Sprockets. Bike Knack also provides Gates Carbon Drive parts for CDC Mudport Belts, CDC Mudport Front Sprockets (5- or 4-arm, 46- to 60-tooth) and CDC Mudport Rear Sprockets (Surefit 3-lobe, Sram G8 and 9-spline 6-bolt).

Your Brisbane Bicycle Mechanic
Are you looking for a Southside Brisbane bicycle mechanic? Do you find it hard to get to your local bike shop during opening hours? I offer a flexible, low-cost service out of my Salisbury workshop, with pride in quality and attention to detail. I am trade-qualified in the mechanical trades and have >20 years experience servicing mountain and road bikes, with mountain bikes a particular specialty. I am passionate about cycling and have a history of competing in road and mountain bike events across my adult life. I know the importance of a well-chosen and well-maintained bicycle, as well as the pleasure of testing your body on a hill, sprint, or technical trail.
Perhaps you’re not sure what you need done? I am happy to offer advice and provide obligation-free quote estimates over the phone or by email. Standard prices (labour-only) are also available via my Pricing Table. Perhaps you have bought parts on the Internet but find you can’t install them yourself? I will willingly provide labour for that. You may be looking to purchase a bicycle or part, but don’t know what option would be best for you. I can provide an independent, unbiased perspective based on my experience with a wide range of bikes and a knowledge of their strengths and weaknesses. For those with an interest in belt-drive bicycles, I also offer a frame conversion service for Gates Carbon Drive. Belt drive is compatible with a single-speed setup or internally-geared hubs, and I can assist you in choosing the best system for your riding style.
If you need to box up a bike for a trip, or learn how to reassemble it after you arrive, I can help with that too. Call me on 0437 017022 or use the Contact page. All enquiries are welcome.
Frame conversion for Gates Carbon Drive
Frame Conversion for Gates Carbon Drive
Until now, installation of a Gates Carbon Drive belt drive system has required purchase of a specialist bike frame. While a number of manufacturers make frames suited for belt drive use, the range of available frames is still somewhat small. Or maybe you already own a frame but wish that you could use it with belt drive? Bike Knack is now happy to offer frame conversions from chain drive to Gates Carbon Drive belt drive. Frame modification is available for road bike or hardtail mountain bike frames in steel, alloy, titanium or carbon. For belt drive conversion, all frames will require a sliding rear dropout or eccentric bottom bracket to allow correct belt tensioning.
Frame conversion for Gates Carbon Drive requires the insertion of a custom frame splitter in the seat stay. Without a frame splitter, belt installation is not possible, in contrast to the situation with a chain, which can be opened and rejoined around the chain stay. In frame conversion, a section of the seat stay is removed and replaced with a frame splitter matched to the seat stay diameter. Bike Knack uses a modifiable frame jig to stabilize the frame during cutting and installation of the frame splitter. After fitting front and rear sprockets of your choice, belt installation and tensioning can then proceed. Both internally geared hubs and single-speed configurations are compatible with this system.
Unfortunately, not all bike frames are suitable for belt drive conversion. For example, ovalized or tapered seat stays are unsuitable for use with this method of frame modification. If you would like to discuss a specific frame conversion, you can either use the Contact page, email Bike Knack on firstname.lastname@example.org, or phone Dave on 0437 017022.
