Eldron Posted September 20, 2010 Share My understanding is that the new AM's are true tubeless ... no need for conversion kits.Slightly heavier than the original version, but a little lighter than the XT's. Mine are about 4 months old and they have the tubeless tape. Looking at the website: http://www.amclassic.com/en/products/mtbwheels/mtb26nondisc.php those look like traditional j-hook spoke nipples (not screwed into the rim) - I can't see how they are true tubeless. Unless by "new" you mean so new that they aren't on the AC website yet. I must say - I can't see it - true tubeless rims would be a completely new rim/spoke/hub technology for AC.

Icycling Posted September 20, 2010 Share I still have a few sets in stock - as mentioned above for R2900 - but the stock is going down quite fast. 4 sets sold this morning and it is only 9:28! Link to comment Share on other sites More sharing options...
WRIGHTLIGHT Posted September 20, 2010 Share Have been riding XT's for a year now, 100% hassle free and 100% bomb proof, weigh 88kg and have had no problems at all.Yes AC's are lighter, but not half as strong.3 of my mates ride AC's and all have had problems with denting and deep scrathes, and one of them is a 9yr old.XT's are the way to go.

Headshot Posted September 20, 2010 Share Have had my XT's for several months. So far bomb proof and smooth running. I do know some people have had freehub failures with probelms getting spares from the SA agents. I weigh 83kg and have had no issues with spokes or anything else so far. They also look like they costs a lot more than R3k - which is what I paid. Link to comment Share on other sites More sharing options...
mikkelz Posted September 20, 2010 Share Yip, aware of that thanks.Also available from Icycling for R2900. Just a matter of getting enough thumbs up on their performance/reliability vs AC Tubeless. Wow! What a bargain x2! Link to comment Share on other sites More sharing options...
wapad Posted September 20, 2010 Share Is this wheelset a worthy upgrade.?Or should I steer clear of them.?Your thoughts/experiences are appreciated. Would luv some AM Tubeless but they are ±R1000 more.Or should I see that as R1000 well spent.? The xt are good wheels but buy them new I used my amc's on Karroo2C and they were great they are fuully tubeless and the weight is 1480 as claimed no conversion tape etc required I do plan to get my xt hub replaced as they will make for good training and race wheels but the amc's are real beauties and the rear hubs spins effortlessly but for 2900 you couldn't be blamed for going xt Link to comment Share on other sites More sharing options...

The company claims that these wheels are: “A magical combination of light weight as well as strength, stiffness and control.” The new tubeless rim is light and at 26mm wide by 22mm deep, it is wider, stiffer and supports the tyre better for improved ground control. It is tubeless ready with a 25mm tape and valve, and either a tubeless tyre or a regular tyre with a latex sealer can be fitted. Link to comment Share on other sites More sharing options...

The only thing required was a valve and stans I watched the tech fit the tyres the rim has smooth finish on the inside I can assure you they fully tubeless the 2009 has a rim tape Link to comment Share on other sites More sharing options...
HowellingWulf Posted September 21, 2010 Share ...some excerpts from a post by Johan Bornman regarding the XT wheelset as I was looking at a pair as well ...However, keep this in mind. A new spoke for that wheel is in the order of R90-00. If your chain overshifts into the spokes, it is 6 x R90-00 before labour. A new rim is in the order of R1000+ Further, some people don't deserve Shimano (cup-and-cone bearing) wheels. They're klutzes with mechanical things and can't seem to figure out when a service is due and when not, thereby destroying the races and ultimately, the wheels....This made me decide against the wheels.Rest of the thread can be viewed here https://community.bikehub.co.za/topic/83209-xt-freewheel-body-damage-after-120-ks-use/page__p__1151527__hl__xt__fromsearch__1?do=findComment&comment=1151527 Link to comment Share on other sites More sharing options...
covie Posted September 21, 2010 Share I just bought a set of AM classics due to a problem with the xt REAR HUB the problem is trying to find a new hub for my XT's they are bomb proof but if you gonna buy them buy them new. I have only had my XT's for 6 months they were second hand and I was assured they had minimal mileage. The XT rim has a strange hub and spoke system . Spokes are also a bugger to come by. If you really cant afford the AM go XT but remember you will need centre lock discs so you're almost at 4k....do wanna buy mine with a dodgy rear hub good price !!! Seems my previous reply to this one dissapeared of the hub, There are two trains of thought and also two threads latley covering both these options. Thread one deals with all the hub problems on the XT (which if you buy them new and under gauruntee should be sorted quickly by the supplier if this happens to you) The second thread deals with the AM Classics bending and buckling quicker than a 2 dolla whore. I would assume the possibility of getting a set with a replaceable faulty hub, should be a lot less of a concern than having your wheels bend and buckle under you on a outride. Especially if your more than 80kg. Link to comment Share on other sites More sharing options...
Tankman Posted September 21, 2010 Share Fork! Took my brand new XT's out on their maiden voyage yesterday and it lasted all of 6.8km before something went wrong!Back wheel is not free wheeling at all and effort must be used to turn the back wheel. Taking it back to the shop tomorrow, so Ill see what they say. Thanks RickyBobby, I didnt see that other thread and based on the mainly positive feedback on this thread I was reading yesterday morning, I thought Shimano XT no problem!
