Dura Ace 7850 TL or CL?

Fancy a set of the tubeless versions of these for the bike I'm building - everyone raves about the CL version but there's little comment on the tubeless version and very few UK stockists on the web - are they a bad idea?
Why hasn't tubeless caught on if the ride quality is supposed to be so good?

because people haven't tried them I suspect. Most of the mtb world has been tubeless for a while now and the benefits are pretty obvious but the wheels and tyres in the roadie world have been slower to come out, so roadies tend to stick with what they know. But I certainly won't go back to clinchers now.
Can't comment on the wheels as I've not tried either. The carbon versions are lighter but there have been a few accounts of problems with them.Facts are meaningless, you can use facts to prove anything that's remotely true! - Homer0 -
Although I run tubeless on my MTB a couple of things are holding me back on the road:
1). You need new wheels (most MTB wheels you can convert)
2). Lack of choice of tyres (big choice for MTB and again you can run a lot of non-UST tyres tubeless to)
3). Most 'punctures' I get on the road as cuts/gashes and I'm not convinced sealant would help on those0 -
Not had the 7850 tubeless ones (BTW, I think these are called 7850SL?) but I have a pair of their predecessors (7801SL). So maybe not much use, but.....
They're in their 4th summer's use now and they have been faultless. No broken spokes and they've stayed 100% true and round, I've never taken a spoke key to them and I'm not the sort to turn a blind eye.
The hubs are amazing. They are still silky smooth. A couple of years ago I bought some new cone spanners to dismantle regrease and rebuild, but once I'd got them apart the grease was spotless, so I left well alone and just tightened them back up. Every few months, I give them a look again, but it seems like nothing gets into them.
I don't do big mileage on them as I just use in summer and I'm a triathlete who's doing other things as well, but they do get commuted on through the rain. I'd guess they've had about 7-8,000 miles.
The braking surfaces are starting to go concave, so they're not going to make more than another year or two, but they have been fantastic.
I would imagine the 7850SL would be a very reliable wheelset and probably a safer bet durability wise than the CL, at the expense of a bit of weight.0 -
You don't need new wheels
I've converted two pairs of open pros to run tubeless and both are fine.
I've run Fusion2s and Atoms now and both are good tyres.Facts are meaningless, you can use facts to prove anything that's remotely true! - Homer0 -
