10x2.125" Tube 0/45/90 degree [Xuancheng / Superbsail]

• The 10x2.125" tube is typically paired with 10" tyres in width between 2.125 and 2.5 inches such as the 10x2.125" tyre but often factory fitted in larger such as fitted by Kaabo in Mantis with 10x3.00-6.
• Available in three bend types:
  • The 45 & 90 degree variants are 104 grams, Superbsail branded with blue ring on underside and understood to be Xuancheng OEM. The 90 degree is easy to identify in product images as having a silver colour valve. The 45 degree (which is also silver) has a slightly shorter length valve than the older brass valve type shown in product images (it is more of the length of the silver 90 degree). Amongst current 90 degree stock, there are a small number of white nameplate Xuancheng branded with designation XUAN CHENG 10x2/2.125, supplied as Kaabo Mantis 10 factory spare (which were supplied with CST 10x3.00-6 tyres - probably not the ideal tube for tyre of that size), if you have preference for the Xuancheng branded leave comment at checkout.
  • The 0 degree (shown in product image with generous length brass valve) is slightly heavier at 120 grams. Observed in non motor hubs on e-Glide and Mearth G120 and Mearth S Pro with the 10x2.125" tyre. When stocks exhausted these will progress to the Superbsail branded silver valve.

Notes:

1. The 10x2.125" 45 & 90's are commonly observed as being paired with CST 10x2.5 tyre which is also stock tyre on many T10-DDM models (Zero 10 / 10X, Dragon X10 & MiniWalker), VDM-10 (Dragon Raptor, e-Glide Mach 10, Bolzzen Dynamo / Gladiator), Kaabo Mantis series 10 series and many Inokim makes. 90 degree on motor hub to clear motor, 45 degree on non-motor hub for swing arm clearance.
2. Typically aftermarket 10x2.5" tubes are fitted to 10x2.5" tyres.
3. Image below shows this 10x2.125" tube (on right) with two other similar size nameplate tubes. The 10x2 straight valve tube on the far left adopts similar size as this tyre and considered an equivalent with straight valve. The 10x2.125" straight valve tube shown in center is designed for 6.5" rims such as the 10x2.125" {-6.5}. Tube nameplate and dimensions are not a conclusive method of determining appropriate fit relative to rim size and often 10x2/2.125" are not nameplated to inform appropriate rim size or compatible tyres, likewise 2 and 2.125" are often co-marked or interchangeable (hence 2/2.125 nameplates). Choosing the appropriate tube is important for puncture resilience.
