Hi all,
Thought I would give tubeless a try so currently have rear tubeless, front tubed. Set up is Rubber Queen 26 x 2.2, standard BC front tyre, rear is UST version, both on Flow Ex rims with Stans tape and sealant in the rear.
I managed to get a small cut in the rear a few days ago just off the centreline of the tread pattern. Cut is about 3 mm long and managed to spray quite a lot of fluid out before finally sealing – took overnight to really seal properly. Understand cuts can be difficult to seal so benefit of the doubt on that one although I had expected it cope a bit better than it did.
I’ve since noticed that I have 6 pin-punctures in the rear as well. All have sealed in terms of retaining pressue but if I leave the bike to stand overnight, I can see dark patches around each penetration where there’s clearly still some fluid leaking out – all are within the tread pattern.
So, questions to those more experienced that me:
1. Is the sealant leakage normal – if not, any ideas how I can stop it?
2. Are tubeless setups more prone to punctures that tubed setups – rear has 7 punctures now, front has none?
FWIW, running 26/23 psi r/f.
