    How's this working out? Any pics of the complete bike? What is standover height on the final product? I am looking for my 10yr old's first 26er and can't bring myself to buy the 31lb Hardrock from the LBS, so am considering building up a variety of frames. I think he can manage anything with an ETT of 22" or less and standover of 28" or less so this Chinese carbon frame, the 14" Sette Reken, the 13.5" Soma B-Side but with 26" wheels instead of 650B, or a small Santa Cruz Chameleon are all on the short list.

    Can't help with stand over height yet. Took 2 months to get rims and I had to wait for those to measure rims ERD to order spokes. Been 10 days since ordering spokes, so I hope to see them next week. Once the wheels are built the bike will be complete.
    Its looking really good and I can tell you the weight should be in the 18ish lbs. range.

    Spokes showed up - Sapim Laser & Sapim Polyax aluminum nipples.
    Was very happy how the wheelset built up = 1356 grams.

    Final weight = 18.49 lbs. I still need to trim some brake lines. He ended up with a very well-used set of XTR 975 brakes with Alligator Windcutter rotors. Rocket Ron 2.4 front, 2.25 rear.
    Pleased with how it ended up with the exception of the boat anchor bottom bracket and semi boat anchor cranks. Eventually I'll have this bike in 17 lbs. ish range once he's done with his Scott Spark RC 24". I'll move the 160mm Middleburn cranks & Race Face Ti BB to this bike. The 2.4 RR & 180mm front rotor are over kill, but I had these parts on hand and will let him burn them off, replacing them with a 2.25 front & 160 rotor.

    Great looking build, looking forward to seeing it eventually get down to 17#.
    As an aside, I notice a lot of kid-build bikes (like this one) and particularly those with significant front suspension wind-up with the handlebars set well above the level of the seat. On any of the MTBs I have ever setup for myself, I've never had the handlebars setup so high. Is there a biometric rational for setting up kids with such high handlebars or is this just the unintended consequence of trying to get them onto a frame that is larger than they would properly fit?

    I'd say your second explanation of "unintended consequence" is the right one. You can get 26er and even 29er frames with very short seat tubes and consequently low standover heights that you can fit kids on but you can't get the bars low enough for kids to be able to climb technical stuff. This is why I think there is still a place for 24" frames, they enable you to get the bars right, particularly for kids racing XC.

    The seat height in the photo's is where he wanted it to hit some dirt jumps that he was going to. For XC rides he'll have it an inch or two higher.
    You see all kinds of 20 & 24" bikes with the seat height a lot lower than the bars and a lot of just comes down to kids don't feel comfortable tippy toed on two or even one foot to get the correct XC seat height like the bikes we set up for ourselves.
    Thanks for the comments.

    I just finished building one of these frames up for my son. Even with a 80mm fork, neg rise stem and flat bars the bar height is still a bit higher in relation to the saddle height than I would like. He doesnt seem to mind though. He is loving it.

    Well done xc71. This build was the inspriation to build one up for my son.

    Thanks. My son is loving this bike as well. Is amazed at how fast it is and the light weight handling. What did yours end up weighing?

    just about 20lbs flat. I had to make some concessions once the finance approval committee ( his mother) noticed what was going on.

    Great looking bike! Looking at building something similar for my wife. Was this officially labeled as a 15" inch frame? How tall is your son? My wife is 5', so that's why I'm looking for small sizes. Thanks!

    any idea what the final cost for the build was? I've got a couple of nine year olds that I need to build something downhill friendly for. This is just what I had in mind.

    I've never added everything up as I had a lot of the parts laying around - some used, some new.The most expensive items were:
    Frame = $315 shipped.
    Sid Race fork = $170, got this off ebay and it was in excellent shape.
    Wheels = $560, that's not including labor as I built them up.
    You can get Middleburn 160mm cranks for $179 and they weigh about the same as XTR cranks.If your not in a rush ( I had made this one a winter project ) you could find the same parts spec or similar keeping on eye on Pink Bike, MTBR Classified, Ebay, Ali express.If you need new parts check CRC around X-Mas with their coupon deals, Getting the XTR 10 speed cassette for $134 was a great deal.
    Good luck.

    Flip the bars - we have a guy that's pretty short that rides a 29'er and flips his bars over to get them lower..... Might be worth a shot to try.

    So I had given my son a used Rocket Ron EVO 2.4 X 26 front tire for this build. One cool thing I've discovered with high volume 26" tires is how close these are to 650B tires. Considering most 650B tires measure in the 27.3 - 27.4" range, this tire measured 26.75".
    He said how well this bike rolls over rocks & roots, but I didn't think anything of it until we started measuring tires.
    For adults looking to get closer to the 650B size, run this front with a Conti Race King Supersonic 2.2, this is a huge volume tire and also measured 26.75". - Also pictured.

    XC71 - Can you repost the pics using IMG[] files, i.e. photobucket or some other online picture. Or just repost/attach the pics. The MTBR server went down and lost a lot of the attached images. Thanks,

    Yes, looks like all the standards are the same as my son's frame with the exception of the headtube has changed on the 15" to a tapered = 1 1/8 - 1 1/2".

    Not sure if you got a frame John. I'm helping a friend build one for his son. The new version FR201 XS with the tapered headtube is still a great starting weight.
    He also scored a brand new Rockshox SID world Cup carbon 100mm tapered steer tube for $400.00. weight is with the remote lockout which he is going to remove and an uncut steertube.

    For the money really happy with the hubs/QR's.
    Wondering which vendor you used for the Circus Monkey hubs... going to get a pair of the HDW2 and would love if they came with the quick releases.

    (though maybe it was a mistake that they were included)!

    Todd, I got the hubs from ebay seller funkyhorse99. They advertise the HDW3 coming with the skewers and I know of a few other buyers that also received the lightweight Ti skewers with their HDW3's. These lightweight hubs/skewers were a bargain - really happy with them so far.
    I believe the seller works for CM, I would message them if they don't have what your looking for listed.

    I found this on Alibaba: Free Shipping!!mtb Frame 26er Mtb Frame Cube 26er Mtb Frame - Buy Mtb Frame,26er Mtb Frame,Cube 26er Mtb Frame Product on Alibaba.com and a couple similar ones listed in 14", 536mm top tube, which maybe even a little short, I think it is about the same as her current Scott Spark Jr 24.

    Need to find one without fake logos, with BSA BB, and double check everything. Sent them a request.

    Just a fyi, you can buy these frames off Amazon too. Prices are the same and shipping is a bit cheaper. If anything happens you've got Amazon covering your back.

    Chinese Carbon XS 26" build

    Received a quote for $420 delivered. Without the fake graphics, obviously. Contemplating. Another option is to do 14" On One 456 Evo, with 100mm fork, but that is like three extra pounds.

    Axe, did you go any further with that frame ^^^.
    I'm stuck between buying a ridiculously heavy and under specced 24" or building a really good XS 26" for my daughter. That is the smallest one i've seen yet which is good.

    Hi all, I brought the CUBE 14" carbon frame 26er. It has a tapered headtube, but I'm not sure which cane creek headset would fit. I believe the frame headtube is expecting integrated headset. The cheap headset I brought from the frame builder is just a bearing that go into the headtube. I'm looking to upgrade to a nicer one.

    XC71, what headset you use for the tapered headtube on your friend son's frame?

    thanks!!

    Not yet, will order in July.

    I have a nice build kit, from my old bike, but for cranks. Debating getting 150mm or 153mm with 28t ring, or 160mm flatland BMX crank (they are much lighter) with 26 front. Rear will be 11-40, with 16t inserted, and Zee derailleur. 160mm maybe a tad too long.

    I do have a 24" full suspension, with a lot of upgrades. She could probably ride it for another year or two... but since I have a kit anyway, and she is tall enough.

    He bought the headset from the frame seller, I had also bought the headset the frame seller was offering. Nothing wrong with them, they have both worked great, just remember to grease the bearing surface as it may creak otherwise.
    I have the Cane Creek 110 Integrated headset on my bike and I don't see the need to spend 10 times the cost for the Cane Creek headset for a kids bike. Sure its better, but these Integrated headsets are just a crown race, two bearings, split pre-load ring and a top cap.

    Thanks for the help XC71! Actually I building this bike for myself as I could no longer find any good 26er bikes anymore. It seems like everyone is abandoning the 26er for 29er and 27.5er. I'm short so I like 26er. You just convinced me not to spend anymore on a headset. I'm way over my build budget anyway and still in need of an XT groupset.

    I brought cube frame size 14 on AliExpress for $420. I choose the UD matte finish so it looks very stealthy. This is my first carbon frame so I have no reference to compare to, but visually the frame looks well built enough. It also has internal cabling for shifters. Sure, there're other frames for $320, but those have external cabling and available in 3K Glossy finish only. Overall, it good enough. I know more when I actually test ride it.

You can mount a 6 bolt rotor two different ways with this hub. 1) Use the standard 6 bolts.And these aren't included with the hub. 2) Install the 6 locktite coated set screws into the hub, place the rotor over them then thread the cassette style lockring into the hub which tightens against the rotor. You can see the lockring leaning against the bottom of the scale. Suprisingly this set up was lighter than 6 steel bolts. The lockring & set screws are 12.5 grams. 6 steel rotor bolts are 14 grams. To go full on weightweenie you could get the set screws in Ti or go with 3 Ti bolts & 3 aluminium bolts. I may splurge for 6 aluminium bolts & run 3 steel & 3 alum. in the front & rear hubs.
    I'm thrilled with the weight on this hub as I looked high & low for a 15mm TA and/or 15 TA/9QR convertible hub & found nothing unless you wanted to spend big bucks. I couldn't find any convertible, light, cheap hubs, and the lightest 15mm TA hub I found was 162 grams.
    I'm guessing this hub is a brand new style for A2Z as they don't even list it on their website. In all my searching I only came across two of these, both from the same seller.
    Edit: forgot to mention the reason I wanted a convertible hub for this build is my son will start with the Sid Race 80mm travel, 9mm QR. When he gets taller I want to slacken the head angle and add more travel with a Sid 120mm travel, 15mm Thru axle.
    For anyone looking for the A2Z XCF-15 front hub which have been almost impossible to find, Torontocycles has stock in Black and red for a reasonable price.

    I'm interested in getting one of these 14" frames. Can anyone who had a good experience give actual supplier names? There are so many of these "companies" and very little quality feedback on these sites.

    Also, what are you all doing for bottom brackets/cranksets? How about front derailleurs, it appears you need to directly clamp one onto the carbon seat tube?

    Thanks for sharing your experience.
