The UST tyres were used tubeless on my other bike before it became more of a DH rig, and before the new Schwalbe’s came out that were all tubless ready.
Think I’ll get some Hope Pro2/Stans Crest wheels and run them tubeless with some new Schwalbes to start with and then see what pops up in the classifieds for the other stuff.
Heard mixed things about i-beam saddles and posts – cheap at the moment at CRC for a brand new one and should save half a pound, but possibly at the expensive of some comfort and reliability.
