Anyone any experience with these? Weight looks ok and I always hear the newer Shimano hubs roll amazingly and hold up well if looked after. Was thinking 240s's but these are cheaper and lighter (apparently!). It'll be for an XC race bike so it probably gets washed more than ridden...
Morning bump.
you can fit an XD free hub on 240's though, which will give you a lighter overall wheel and a larger range of gears (assuming 1x)
this guy does cheap 240s (link is for 32h hubs only)
you could get this
and convert it to 15mm

M9010s are 265 and 137g
Centrelock 240s are 218 and 265g
6-bolt 240s are 230 and 145g
So XTR are still heavier than 240s, plus you can't fit an XD body, plus Centrelock rotors weigh more.
Personally I'd have 240s every time, but Shimano hubs do indeed roll nicely!
I'd have DT240 too for XC. More a maintenance thing and ability to run XD body. Shimano are lovely for road though.
Weird, the quoted weight of 240's must have been wrong that I looked at! Can't see me ever buying a SRAM cassette, I can't afford to drop £150-£200 on a cassette while the kids are still living here! I'll be running 10 speed for a while.
At the moment just looking at a rear hub, front is fine and is running a dumb arse Specialized OS28 end cap thing in the fork. Will stick with it until the fork is dead. Rear hub is a weird design with the tiniest bearing I've ever seen in the cassette side that keeps dying, was making a weird weird noise at the weekend too!
Thanks for the links, will have a neb!
What does "roll nicely" mean in a hub?
What does "roll nicely" mean in a hub?
Spin a load of wheels in a jig and the Shimano one keeps going a very long time. I can't imagine this translates into any measurable real world advantage whatsoever (although CeramicSpeed make a huge amount of money out of their friction-reducing bearings, so who knows).
But you knew that already, so why pussy foot around it?
😛 As above, at the end of the day it probably doesn't make any real difference but saying that I'm training hard (ish), nice things feel nice and even if it's only placebo it's still a positive. Nice things also generally last longer but as has been reported, XTR pedals are a bit rubbish so I wanted to put the question out there.
At least you're consistent with your hate for everything Al.

XTR pedals were a bit rubbish in their M980 guise, but had been superb before then, so one hopes (/assumes) they'll have fixed them for the M9000 iteration! The USP of Shimano pedals is that they last a million years, at the point at which their durability is poor they're a pretty bad choice of pedal!

Just checking there's nothing to it, and wondering why folk who know it's meaningless ascribe some benefit to it.

What a load of shite! How does asking a question equate to hate?
6-9 watts for ceramic speed bearings apparently
I see they do a chain no 2-5 watts optimised for 200 miles
What happens then? Is it useless?

Even their low-end hubs roll fantastically. My girlfriend has them on her £400 Cube hardtail and once set up properly with the cup and cone spanners they spin on and on like the Duracell bunny. Much better than sealed cartridge hubs, although I couldn't say how this affects real world performance.

It must be your delivery, in most threads of this type I see you contribute to your "questioning" generally comes across as hate.

I put it right at the end, as a bit of a nod to the fact MF had commented on it. But as DR said, apparently there's a 6-9W advantage from having nice free rolling wheels. Will [i]anyone[/i] notice that in terms of on the bike feel? Doubt it. Will it have an effect on performance, however minescule? Yep.
And it was a leading question you were asking, you knew the answer, but just wanted a chance to shoot people down. Your MO is getting far far too predictable.

I read about that, it's a normal chain after that! Mental.
cynic-al mythbuster! It just irritates me seeing guff here.
I'd be interested to know the ceramic comparison - is it with well adjusted smooth hubs or tight knackered ones?
It's for cartridge bearing hubs. Was merely suggesting that very 'free' rolling bearings can offer a very marginal performance advantage.

Race teams/minted fanatics have to buy a new chain every 200miles. Top marketing.I read about that, it's a normal chain after that! [s]Mental.[/s]Genius!

Pinch of salt for the marketing guff... but 30 to 60 seconds over a 25 mile TT is definitely not marginal. Not looked into the tests though to see what the baseline is etc.
6-9 watts is decent, I'd love to see the actual test results, seems like a lot
Do they do headset ones? 😛
6-9 watts would have got decker the hour record

Ok, I'll be the cynical one for a second...yes!! And in the press release they were extolling the virtues of the ceramic bearings reducing flex or some such guff, now that was deserving of some hate!!
Those bearing kits from ceramic speed are insane money, even if it gave me 10 Watts and half an inch I still couldn't quite afford it......obviously it'd go straight on the CC though!
I guess you'd waste less energy steering your bike TBF!

haha
the chains they do are a company they swallowed up

What are Ultrafart bearings?
