Now i have to get the wheels trued as a few rides in- they wobble like all hell :D Yes- pinch flats :) That’s why i decided to go UST as well…..they were killing my rides.

Just from my experience, if you're going to go tubeless use a proper UST tyre, especially if you're a bit on portly side. I found that Eskars 2Bliss tyres just squirmed horribly when I went tubeless with them (they were a great tire with tubes). The UST RQs on the other hand are super rigid even at low pressures. The only advantage I see with the tubeless setups are puncture resistance. Those that try to save weight at the same time are just asking for trouble. UST + sealant FTW -which will typically add a fair bit(~100-150gms) of weight over a regular tubed setup. If you're not getting regular pinch flats I really wouldn't bother.

The rim tape and its seating it pretty much key isn't it? My second wheel took me 30mins- yet the first a few hours and it needed to have the stip re-aligned too. lol....I offered to help Brent with his conversion- but we went for Chinese instead and then he took them to the bike shop.... :D My 2.4’s required some serious leverage- there was no way they were going on with just my hands.

I hear that folk have great results with that setup. I would have gone that way with my existing wheels but there were just to many dings for it to realistically work.

i still need to go tubeless, which means new rims, which mean more money

The only explanations is that maybe the larger 2.4's UST are *a lot* easier to get on than the 2.2UST. I had no problems with the 2.4 front non-UST. I did it with my hands without much pain. The 2.2UST on the other hand was a complete bitch to install. Even getting the first bead on was a nightmare and the second bead defeated Cycle Trading and the guys at BikeHQ took shifts to get it on *with* tyre levers. Even then I noticed that the bead wasn't sitting properly and was burping a bit. I then spent another 2-3hrs replacing the rim strip and tape, and made sure that the bead was sitting in the corrects channels. It now sits perfect. I reckon the DT system is better for creating a perfect seal once it's on correctly, but boy is tricky to get the bead to sit when the bead is as tight as it is with the RQs. In comparison running Eskars with the rim strip were a bit tight to get on, but I did manage to do without resorting to tyre levers. Heh.

I'm now carrying the Topeak levers in my pack when out on the trail though- as other levers would just not do the trick i think. Yesterday's ride to Godley put the tyres through their paces and I love the setup all ready. They just "feel" so much more connected to the trail- they kind of mold around stuff. I'm sure the bigger bag helps- but yeah- they feel real nice. They roll pretty well to at 1050g vs the 710g of the Specialized Eskars. Very happy.

DT 5.1's are tight rims, even tighter with the tubeless conversion kit!! Does depend what tyres you are running though. Maxxis tyres do seem to be a lot easier to fit than many. I used to find the Specialized Eskars to be a tight fit, but not too bad with the 5.1, but putting the Intense 909's on to the 5.1 is a bit of a nightmare as well! Yep.
