    Disc Rim: Alex XCR Pro Scandium - 315g

    I got these nice rims:

    Alex XCR Pro Scandium
    eyelets (!!)
    32-hole
    315g

    I was able to weigh 20 pcs. and got the lightest samples for myself
    the lightest ones were around 315g, most around 319-321g and one weighed 327g. The finish is just perfect. the weld is hardly visible at all.

    outer width: 23,3mm
    inner width: 18,5mm

    I will lace them to some no-Name hubs and try them on my winterbike. The hubs are lighter than some DT240 and alltogether the wheelset should be around 1300g. i hoped for 1250g but since the rims came with eyelets they got about 15g per rim heavier. i am glad they have eyelets though as building the wheels is much easier. the next hubset i will lace these rims to will be my old Amclassic hubs which then should closely reach the 1270g mark.we will see...

    there's still plenty of stickers all around the rims so a couple of grams could be saved by removing them as well.

    Weights seem pretty consistent, and these seem like a good chance to build pretty light wheels without spending a fortune. I'll probably wait to hear reviews but hope to grab some early next year. Glad that they are close to claimed.

    I thought they do not have eyelets

    http://cgi.ebay.com/Alex-Rim-Scandiu...742.m153.l1262

    Is then there an option when you buy them? To buy with eyelets or without eyelets?

    That Rim profile looks VERY similar to Stans No bead hook design in my opinion. That'll be interresting to see how long those last.

    3mm tall bead hook or what a heck do you call that. it seems very small to hold a tire in place.... wide tires will be a problem on these rims.

    What about a V-brake option?

    not so.

    ZTR RACE inside cavity 21.4mm - nino said these are 18.5

    width adds a lot of stability to the ride of a tire at low pressure.

    this is the profile:



    so, removing stickers, do you think could be used for rim brakes?? (the V brake version does NOT exist)

    Its a small rim width, it will not add stability to the tires, compared to wider rims.

    I would say no. V brake rims' brake track is usually machined after welding of the rim to remove any lateral run out. Also I believe V brake rims require stronger side walls and some have internal bracing to prevent the collapse of the brake track.

    A friend scooped a set; weighed em at school for 299g ea untouched.

    His rims are holding out solid, he beats em worse than I beat my stuff. DT240s hubs, I can't remember what they weighed put together. Light rims for sure.

    299 grams...do his rims have eyelets? Does he run them tubeless? If so, what rim stip does he use? I'm wondering if these can be used tubeless via Stan's yellow tape. Thanks

    The rims in the original Alex XCR Pro rim thread that mentioned these were eyelet free, and that was likely part of the reason that had a limited weight capacity. The eyelets would explain the weight difference.

    most probably no eyelets. Eyelets add about 15-20g per rim.

    These look very interesting, do you have their ERD? I couldn't find it anywhere...

    Anyway, Nino keep us posted how they hold up

    Nino's rim as you can see have Eyelets hence the extra 15g

    The above pic with the red background looking at the rim towards the background can be seen not to have eyelets hence the sub 300g weight.

    It will be interresting to see how long they last as there smack bang inbetween the Olympic Rim and the Race Rims yet appear to have a similar rim profile/design - although who knows how long this will last going by the current lawsuit.

    I disagree that the Alex XCR Pro cross section is similar to the Notubes Bead Hook type...

    Alex XCR Pro Rim. Notice that there is a greater flat section before the hook starts


    Now compare with Notubes cross sections. Notice there is very little flat section. Which Stan's claims is what gives tires their extra volume and greater contact patch.


    A good question to ask is how would the two compare in terms of lateral stiffness.

    Another question is if you run tubeless -- the Stan's design can be run with just yellow tape, for a couple of grams penalty. These Alex rims would probably need the rubber rim strips, all of mine are 60g each. That'll even things out -- might even tip the tables back.

    Dunno if other, lighter tubeless conversions are available, or would work with these...

    If you are going to run a tubeless conversion using non UST tires, I do not see why anyone would use anything other than stan's notubes rims. It is not like the Alex XCR Pro rims are cheap. They are more expensive that ZTR Olympics...

    tubeless vs. tubes....

    i am currently using prototype inner-tubes which offer lighter weight AND puncture protection at the same time on my Scale. At the same time i am running lightweight Conti Tubes on my winterbike using the same Conti raceking 2.2 tires where i get flats at least every other ride i have 5 (!!) repairs on my front tube alone...3 on the rear. i used tubelesskits for the last 7 1/2 years with maybe 3 flats total over that period. it's a whole new experience to get flats again. not that i like it but it just shows that i have forgotten how much those inner tubes $ucked.

    if i would run tubeless i would use the 20g Eclipse rimstrips anyway. The Eclipse kits weighs 35g per wheel (rimstrip+valves). But correct - that's still heavier than Stan's yellow tape for sure.

    But as mentioned i am running tubes that might make tubelesskits obsolete anyway

    still no more details on the tubes but rest assured they are the BOMB!!

    i expected to get the wheelset saturday but it turned out they didn't even have started with the build....oh-well.hopefully mid this week but we have snow right now so riding is limited anyway.

    These rims are lighter than Stans Olympics and come with eyelets which is a big plus for any wheelbuilder and also for the long term.Alloy nippels tend to seize in non-eyeletted rims and also make tensioning less easy. I have to admit i was not expecting eyelets as well but i really like them now. my wheelbuilder had a big smile...
