Hubs

A: First positions are always taken by hub name (model name), in this case, it is hub D792SB. Some other examples would be FS522SB, D791SB, XD602SB, etc.

After this model name there can be the following letters or combination of letters and numbers:

• /A – means that this hub comes with Japanese EZO bearings (if there is not /A it means that the hub has Chinese/Taiwanese NBK bearings)
• /AB – this means there is 1x EZO bearing and 3x NBK bearings
• -AA – means Alloy axle and Alloy cassette body with 3 pawls in this hub
• -A4A – means Alloy axle and Alloy cassette body with  4 pawls
• -A5A – same analogy, Alloy axle and Alloy cassette body with 5 pawls
• -SS – means Steel axle and Steel cassette body with 3 pawls. You can see all kinds of combinations like -SA, – S5S, -S4S, A4S, etc. where letters represent the material (Alloy or Steel) and the number indicates the number of pawls.   
• -SL – stands for Super Light hub
• -HL – stands for High-Low flange and it means that the flanges on this hub have different sizes, they’re not the same
• -ABG – means that the freehub body comes with A.B.G. feature (Anti Bite Guard), which is a steel plate on the freehub protecting it from bites caused by the cassette
• -B12 – means this is a Boost rear hub for 12x148mm frame spacing
• -B15 – indicates that it is a Boost front hub for 15x110mm fork spacing. You can see sometimes also B5 or B20, which is again a Boost hub for 5mm QR or 20mm through axle, you get the idea. 
• -XD – stands for SRAM XD driver so it means the hub comes with XD driver. If there is no XD in the description it automatically means that the hub comes with Shimano freehub.
• -11S – means 11speed freehub body and please note it is always for Shimano HG body (this hub can take Shim 8/9/10/11s cassette).
• -S11 – means 11speed freehub body and please note it is always for SRAM XD driver
• -MS – means freehub body is Shimano Microspline 
• -20 – means that the hub is ready for 20mm through the axle. Sometimes there can be -15 or -12 which again means 15mm or 12mm through axle.
• -CL – stands for Centre Lock hub. If CL is not mentioned in the description it means automatically that the hub has 6 bolt disc mount. 
• -X12 -says that rear hub is for X12 (12x142mm) through axle (142mm frame spacing)
• -BO – stands for Bolt On type of dirt jump hub model
• -9T – means the number of teeth on the drive unit or sprocket for dirt jump and BMX hubs. It can be also 11T (11 teeth).
• -14H – means type of axle (axle M14 hollow) for dirtjump and BMX hubs

To have all abbreviations covered let’s mention also SB, CB  or SBT in the model name, for instance, F482SB, D411CB, or A165SBT. Moreover, the model name starts with the letter F, D, or A, sometimes XD so this is the explanation:

• A – represents non-disc Front hub, mostly road hubs (example: A291SB, A141SB, A171SB, etc.)
• AS – represents non-disc Front hub for Straight pull spokes (example: AS511SB, FS622SB)
• AH – represents a non-disc Front hub meant for Downhill (example: AH41SB-20)
• F- represents non-disc Rear hub (example: F482SB, F192SB, F162SB, etc.)
• FS – represents non-disc Rear hub for Straight pull spokes (example: FS522SB, FS502SB)
• D – represents disc, both Font and Rear hub (example: D791SB, D792SB, D462SB, D642SB, etc.)
• DS – represents disc, both Font and Rear hub for Straight pull hubs (example: DS51SB, DS52SB, DS11SB, DS12SB, etc.). Please note it’s not a rule that the letter S is always in the name of the straight pull hub (for example D411SB, and D412SB are straight pull hubs)
• DH – represents disc, both Font and Rear hub for Downhill hubs (example: DH61SB, DH42SB, DH82SB, etc). But also D541SB-20 can be used as the front Downhill hub despite not having the letter H in its name
• XD – represents disc, both Font and Rear hub, but the letter X means that the hub was in the past or still is in the present days dedicated for Novatec wheels only (example: XD641SB, XD642SB, XDS641, XDS642SB, XD611SB, XD612SB)
• SB – stands for Sealed Bearing so all hubs with ball-sealed bearings have this in their name (example: A291SB, A141SB, F482SB, D791SB, D792SB etc.)
• CB – this is how carbon hubs with sealed bearings are being marked (for example: D411CB, D412CB, AS61CB, FS62CB, etc.)
• SBT – this is how hubs with sealed bearings and Threaded axles are being marked (example: D252SBT, D236SBT, A185SBT, A186SBT, etc.)
• GCC – this is how entry-level loose ball hubs  (mostly Joytech brand) are marked. You can see also RCC, DSE, TSE types which are all loose ball hubs with the only difference being in the quality of materials used on cups and cones and also in the type of sealing used on those hubs. (example: D341GSS, D342GSS, D041RCC, 801TSE, 802TSE etc.
• Cassette bodies use markings such as:
• Shim.9 – means this freehub is suitable for the Shimano 8/9/10-speed ROAD cassette and Shimano 8/9/10/11-speed MTB cassette.
• Shim.10 – means this freehub is meant for Shimano 10-speed cassette only.
• Shim.11 – means this is suitable for 8/9/10/11-speed ROAD cassette and 8/9/10/11-speed MTB cassette. Whenever using less than 11s Road cassette please use also the spacer (ring) that comes with this type of cassette body.
• SRAM XD – this driver can take 11 and 12-speed SRAM XD cassettes.

A: No, it is not possible to convert a boost hub to a non-boost hub by changing the axle or side caps.

Using an additional spacer will cause either a mismatch of the disc with the caliper or will convert the bicycle from a one-track vehicle to a two-track vehicle.

A: First, check if there’s a production code (serial number) printed on your hub shell. It’s a 12-digit code that helps us look up your hub’s full specifications in the factory system. Simply provide this code to the Novatec EU team, and they can quickly confirm the exact hub model for you. You can see where the code is usually located in the photo below — most often on the hub shell, but sometimes on the flange or another area.

You can see where the code is usually located in the photo below — most often on the hub shell, but sometimes on the flange or another area. If your hub doesn’t have a production code, especially in the case of older or custom models, don’t worry — we can still help. Please send us clear, detailed photos of your hub from different angles. Try to include the freehub body, end caps, and axle type, as well as any markings or logos. Using these details, the Novatec EU team can usually identify the model and recommend the correct spare parts. Please note that some unbranded or custom hubs are produced in the same factory as Novatec hubs (Joy Industrial Co. Ltd.), but they may have different internal parts.
Even if your hub looks very similar to a Novatec model, we cannot guarantee that Novatec spare parts will fit unless it has a Novatec logo or production code on it. For that reason, Novatec EU can only ensure the correct spare parts for official Novatec hubs.
