CST 9x2" Tube 45/90 degree

• The CST 9x2" tube is ideal for Dualtron Popular, split rim variants of Dualtron Mini and Togo.
  • These models adopt a 6.1" rim. The Dualtron Popular introduced an 70/50-6.1 tyre (2.75" wide, near 9" diameter) which is typically retrofitted to Dualtron Mini in lieu of the original Dualtron Branded CST 8.5x2 tyre. This tube suits both of those tyres.
• Also a good option for Bolzzen Commando 4818, which runs the 9x3.00-6 tyre.
• CST 230x50 tyres (MiI3/MI3Lite/MI44).
• Progressively being adapted for application in 8.5x2 tyres (including the forementioned CST).
• Choice of 45 and 90 degree bend, 80 degree tilt. The 45 presents more like 60 degree.

Notes:

1. This tube presents similar to the CST 8.5x2" tube and has started to be offered in leu of 8.5x2 nameplate branded product, suggesting it is universal for 8.5" and 9" tyres on 6.1" rims, including the common 8.5x2 "Xiaomi M365" tyres.
2. For motor hubs typically 90 degree is adopted, non-motor hubs 45 degree (e.g. Dualtron Popular rear wheel drive: rear 90 degree, front 45 degree).
