Have just fitted some Nano 40’s to my Alexrims 26cxd rims and found them a utter nightmare to get on, tightest tyres ive ever fitted, both went straight up tubeless , but now the rear is soft, need to inject the sealant now and hope for the best ! .. whats the best way to get the sealant into the valves ? .. syringe from ebay be ok as cant pop the tyre off to install the sealant !

Yep properly tight, the whole range. Assuming their presta valves, i’d imagine popping the bead off is still the best option. Get some tyre lever to deal with them, perdos worked with mine (with a slight fight), otherwise what are you going to do, if they do puncture while out? Tubeless has let me down in the middle of winter, miles from home it happens..

Putting them on my wtb rims was the easiest tubeless tyres I’ve ever done, literally 10 minutes for both tyres…

I realise this is of no help to you whatsoever… 😐
