    AM Rim Thread

    Sweet forum! I'm getting the itch to start doing some exploring on my Bullit; it's already en route to an AM/FR build.

    My rear rim is about to break at the seem, so I'm trying to figure out the best replacement. I would like to find something in the 28-32 cm range that is the lightest, most durable rim that can handle gnarly trails with some lift-served riding thrown in.

    Mavic 823?
    DT 5.1?
    Any others?

    Thanks

    Good job! AM wheels

    I second the motion Mavic 321 are great rims for AM and lite enough to handle the hills, at a price that wont give you a hart attack

    A lot of people seem to be digging the DT 5.1.

    I've no experience of them but I love my DT 4.1 rims.

    I'm running the DT 6.1's. They seem decent enough. I only have them because the shop didn't have any DT 5.1 rims in stock or any Syncros DS28 rims and i wanted to try something different to Mavic.

    I had the 6.1's retrued after the first 3 rides but i'm hoping it was only because of stress relief in the build. They seem alright now after about 20 rides.

    I've got a set of Syncros DP25 rims on mine; seem to be doing well so far. No problems with fatty tires and low pressure so far, and they've held up fine for over a year of moderate abuse.

    Caveat: I only weigh about 165# max when fully loaded on the bike.

    If doing the build again, I'd probably go for the slightly wider DP28 rim just for the hell of it. If I end up trashing these, that's probably what will replace them.

    Probably can't really go wrong with any of the options in this thread; go with what you get a better deal on maybe? Guess it depends on if you want tubeless ready as well.

    I've used all of these and can't say that I prefer one over the other. All worked well.

    Syncros DS-28
    Mavic XM321 / F219

    Thanks for the suggestions!

    Has anyone tried the Salsa Delgado Discs? They seem ridiculously light (claimed 450 g) for a 29 mm rim? I wouldn't think that they would hold up to a hard beating, but the rims are listed at about $60 in the QBP catalog.

    for the burl of a bullit, i second the FR6.1d. 100g heavier than the 5.1, but gives you peace of mind on the bigger stuff.

    I'm old school... I like the Mavic F519 still. I think there's an equivalent with the new naming, I just don't know what it is.

    I also had a set of Alex Supra-D, but they were heavy and needed truing a lot. I think they are DH race rims.

    Or it could be that I'm comparing my WTBs to my dream set of Hadleys with 321 rims. Whom would I complain to if one of my spokes broke on my dream wheelset?

    The new version is called the XM719....and I can't think of a better allmountain rim. It's got a great price, it's not super heavy yet guys are doing up to 12' drops on them with zero problems. Mine are round and true after a year of riding, will accomodate up to 2.5 tires no problem, and tires are easy to get on and off this rim.

    Also, they lace up really nice - great tolerances. If you ever want to swap them to a bike with V-brakes, you've got a sidewall for braking too.

    So... what's a nice weight figure for AM/XC oriented wheelset...

    I busted a spoke yesterday and sent my rear wheel totally out of true (the front already was). Totally my fault, boneheaded approach to a curb, not enough bunnyhop and already loose rear spokes. That's not to mention the failed little jump, but that one was hard on the front, not the rear though.

    My current set-up is Shimano 555 flangeless hubs with a Mavic 221 up front and a no-name cheapo rim and 14g spokes.

    After yesterday's ride, I realized I may go for beefier rims, even at the weight increase expense.

    Another vote for the Mavic xm321. I got the wheelset (with XTR hubs!) for $149. It was a custom build that never got picked up. I guess the '80's purple nipples made it too ugly, so I got it for a steal.

    I ahven't had my XM321's for long, but I think they're a good compromise between light weight and strength. Think I need to re-build them with the right length spokes and a spoke tensioner.

    DT 5.1d's with Hadley hubs and Dt Supercomp spokes. They have taken all the abuse I've thrown at them and after 6 months I haven't trued them once.

    I'm thinking that EX721's or DT 6.1's laced to Hadley's would be nice. I'm thinking of running some 2.5 High Rollers on this wheelset, so I don't want to go too narrow. My emphasis is on the descent. I don't mind pushing when I need to

    I do admit I'm predjudiced

    because I own the following

    Best AM wheelset - Industry Nine wheels with freeride spokes and Stans FR rims.
    Best AM bike - Ventana El Capitan

    The rim choice will depend on how rough you really ride and that question only you can answer. Also, do you want tubeless or tubes?

    In my opinion tubless is good for DH racing, where you want major beef for tires and don't want to be penalized with a tube that weights over a pound as that slows your acceleration. It is also good for DJing, where you can pinch flat easy.

    For trail riding a middle weight tube, like the Maxxis Welterweight is the optimal solution as I found out though over a year of experiments. This year alone, 3 trips to Moab, very rough, very high speed trails, increasingly tougher drops and not a single flat on trail, yet. I'm running FD28 rims with Fat Albert tires and Weleter Weight, shraeder valve, tubes. (I just totally jinxed myself)

    But as far as rims are concerned, as that's the question, the lightest weight 28mm rims are Alex FD28s (I have a set built up) at 490g, the mentioned 5.1ds at 510g and the 450g Salsa Delgados (29mm wide). I haven't had or heard any real world experience with the delgados, the FD28s have held up great for me, but I haven't hit anything bigger than 5ft out on trail. They seem equally capable to the 5.1s. They are made of a different material, however. A friend of mine who is definatelly more aggresive has hit upwards of 10ft to tranny with 5.1s and has put a few dents into the rims. He's also destroyed the 6.1s, but those were subjected to about 14ft drops and were built a lot worse than his 5.1 set. He claims that the aluminum alloy DT uses is too soft and too bendy. I can't comment on the FD28s as he's not run those yet, but they have held up great for me and are about a third of the price of 5.1s.

    Going a little heavier you've got Mavic 321s, Rhynos, Syncros DS28s and more. For a more complete list check out this thread: Going back to tubes, help choose a rim: Alex, Azonic, Syncros, Sun, Stan's, Tioga, +.

    What size tires are you running?

    I gotta agree about the Mavic F519. I have one on the rear and love it. I have done 5ft. drops to flat and it never needed truing since it was built up. They are a little narrower than what you're looking for, but they're incredibly light at about 466g and are really cheap. Be aware that a F519 costs around $30-40, while an XM719 costs $65-70, like said above, the XM719 is just a renamed F519 so if you don't mind the sticker, you can save 40 bucks by buying an F519.

    519 has been a great rim for me. Takes a lickin with no true-in. A good builder helps. Nice and light for how strong they are. Over 2000 miles with lots of 5' and under drops.

    Mavic 819 USTs with King hubs are the best that I have ridden on. I am also very interested in the DT Swiss 5.1d they seem preety sweet and that 240s hub.

    So, can we say that 2 kilos (4.4 pounds) is a good weight figure for a AM wheelset?

    My cheapo planned wheelbuild will be around the 2.3 kilos (almost 5 pounds)...

    Second on the Outlaws

    I second (or is it third) the Azonic Outlaws. Tough as nails and not nearly as heavy as a DH rim. They won't win any XC races but they rule for long rides with a few drops thrown in for good measure...

    I ride both Azonic Outlaws and XM321's.
    I would vote for the 321's. The outlaws are a nice strong rim for DH or FR but IMO a little heavy for all day trial riding. Plus you don't need 36 holes on an all-mountain bike (I weight 260 and 32 holes work just fine for me).
    I have been riding 321's for over 2.5 years. They came stock on my Coiler and I built a set for my Inbred XC hardtial. I have had no problems with them and would recommend them and again I way 260 and ride extremely rocky trails.

    I

    I've had the F-219s Disc (current XM321) in the past. Those are tanks.

    I switched to DT Swiss 5.1.d - These are dreamy!!! As beefy as the 219s, but lighter...

    ...oh, and sexier!

    Got them laced onto Hope ProII hubs. Really think these are the All Mountain rims.

    It seems some of the recommendations are going into more FR territory. What about something like XC819's?

    After earlier suggesting the DT FR6.1D rims i went for a ride today and came back with a dent in the sidewall and rim cavity. I can't even think of what i might have hit to have caused it. The wheel is still round and only about a 2mm buckle at that point, but i can't help but feel that the reviews on MTBR saying these rims were soft might have been right. The tyre still holds okay and i should be able to straighten it when i need a new tyre.

    Just built up some EX 721's over the winter. Havent really had a chance to push them early in the riding season, but they appear to be nice. It's held a 2.5" TrailBear with innertube well so far.

    In farness, I'm a lightweight rider. Not very hard on parts. Maybe a clyde can chim in for comparison sake.

    AS someone else mentioned. A well build 32 hole should be plenty sufficient for AM.
