    Sun Ringle EQ21 Rim

    I know some people have these built up, wondering about the durability versus a DT XR 4.2D or mavic XC 717

    I've got a set, and they don't show a single scratch yet... I guess I'll have to punish them more often, but the Netherlands aren't known for their mountains and rocky terrain, now are they?
    Its a light rim, but also has a tiny cross-section, so material-density isn't all that small. If laced properly, they should take quite a beating.

    I dont see how those can be used with a mountainbike tire... Their internal width is only 16MM!! Thats like road rim widths!

    Don't forget that the (very popular) Mavic XC717 has a internal width of 17mm and people ride them with 2.3" tires... so 16mm should do nicely up to 2.2" or so.
    The mavic Crossmax-SLR wheels are also 21mm outer width, with an innerwidth of 17mm.

    I run EQ 21 with RK 2.2 without any problems

    I'm using a EQ27, which is wider and stronger and works fine. My only complaint is that mine came with the seam unproperly finished (the seam was sharp and lumpy at the bead seat).

    I wouldn't use Mavic XC717, they tend to crack.

    My eq23 has been fine for the couple years ive used it. Ive bashed it into plenty of rocks weighing between 190-220lb. The 21 should be comparable, just smaller.

    .. its really narrow though. I use 2.1, or small 2.25's on mine, and thats pushing it. You can install big 2.3's on 717's, and people have, but its a floppy sloppy ride unless you like pressures sky high.

    A velocity blunt is 410g and wide enough to fit reasonable tires.

    Hi!

    I have a terrible problem. I got two secondhand wheels built with Sun Eq 21. I just found installing tires on these rims almost impossible. I tried Hutchinson Toro 2.1 and Continental Speedking 2.1 with no success. Although I managed to install my old Michelin Country Mud on the front wheel. In the shops assistants are sceptic they don't allow me to try their tires on my rim to see if they fit and people told me, it 's normal to require huge efforts installing a tire. But it s far more than that they imagine.. They don't understand the seriousness of the problem.Steel levers don't help. They harm the rim. This god damn rim sucks. Serial problems i guess.. Eq 23 for example is said to be more easy to handle. I ask someone from Sun Ringle, hoped he will probably offer me some suitable tire with ''bigger'' bead. . But instead of that, he gave me some not so effective tips like soaping, heating the tire etc.. Id like to ask anybody experienced with Eq 21 to offer me some tire which relatively easy to install.
    Thanks.
