    •   Going on a 26" spank subrosa / lends nevegal combo... I don't go below 30 unless I'm at a muddy competition in the pouring down rain in Spain. So never More nimble eh? I wonder how only the front wheel will feel..
    • F**k that drop gap attempt at the beginning  
    • Joe's make car type tubeless valves if you are allergic to presta.

      I thiiiink it should still work with wider trials rims. The main thing that would make me lose air is folding the tyre, I run narrow rims so folding a tyre is pretty easy at low pressure. I think with a wider rim it should be fine.

      Basically if you fold your tyre now with normal riding, you might struggle with tubeless but if you rarely fold your tyres from the rim you'll be fine. I run my tape to just before the beads. 
    • I ride mostly skatepark so in terms of pressure im a little higher than ali. 45 minimum really. In the latest tubless vlog ali made he put the pressures down to 30psi and it still worked great - worth a look on his youtube.  For the tape i probably went a little wide but its seemed to work. Ran it completly from rim edge to rim edge making sure i had stuck it to the metal as tightly as possible.  Presta isnt as accesable as shrada valves but you can get an adaptor and put it in your pocket - fashioning one might be difficult to make it air tight. 
    • Surprisingly when i went to the bike this morning it was still fully inflated no tubeless liquid anywhere (could be because the tyres are like 3 months old). So looks like its gone well.  Went for the first ride this afternoon and it feels completely different to before but i like it. Makes the bike feel very nimbal.  As for the foam it was very time consuming cutting it so next time will leave it if its worked for you!    Thanks for the advice
