Okay here goes…
As previously mentioned, prior to receiving the wheels I asked Superstar if they could be used tubeless (they were advertised as such). I was told I would just need yellow tape, valves and stans fluid.
When the wheels arrived all looked good. I taped up the first rim with yellow tape and then fitted the tyres – alarm bells! The tyre went on far too easily. When I tried to inflate the tyre it was impossible – air just escaped everywhere, the tyre was not a tight enough fit.
I emailed Superstar who apologised and said it was a typo on the website. The rims are not ‘tubeless ready’.
I have since returned the wheels, and bought the Stans Iron Cross on Tesla hubs from Superstar. I’m now running these tubeless, and they have been faultless so far.
