    24" Wheel bike completed

    Finally finished collecting parts and building the bike.
    Happy with the way it came out.

    There are some opportunities to shed some weight but 21.6 pounds with a full set of gears and a suspension fork is not too bad.

    Sweet ride! I'm in the process of doing the same for my 10 yr old, how about posting some specs?

    I love it! How old is your son (daughter?)? And if you don't mind, do you have an idea how much $ it ran you?

    My kids are 9, 7 and 5 years old and petite. It fits the 9 year old well as she is about 51 inches.

    Height and ability are better factors for what size bike you need. Not age.

    I try not to push my kids to the next size too early. Though bigger wheels roll faster most people feel more comfortable in technical terrain on a smaller size frame.

    Column D of the spreadsheet above is cost and not shown, lol. I do my best to track the weight and cost of every item even if it comes from the parts bin. It didn't get there by magic and at one point had a cost. I bought the frame almost two years ago after I began reading this forum and slowly collected parts over time as I found good deals. Having said that it would be cheaper to buy a new bike from the LBS and make a few smart upgrades.

    This bike should see over 5 years of continuous use with me before I give it to my brother for his boy. That much love and the good times that go with it really have no price.

    Love it! Good looking bike. My 10yr old son's 24" Haro far out weighs my 29ers. Close to 30lbs! I'm finally finished collecting all the parts to start building hima 26" Sette Reken.

    What would you do for a first, biggest bang for the buck upgrade? My son's 24" HotRock 7-speed is all stock, could use a diet, as well as some upgrades, but I don't know how long he will end up riding it before he outgrows it, and don't want to toss too much money away if he moves up pretty soon.

    Tires! Kenda Small Block 8, 24x1.95, can be found for less than $30 each. They weigh <450 grams each. The stock Bontrager tires on my son's 24-inch bike weighed over 800 grams each! Total weight loss was almost two pounds, for less than $60.

    Thanks for the positive replies.

    More Pics

    I think Joe is right, tires are usually a good place to save weight no matter what size bike.

    Here in So Cal we have a very active craigs list and a couple of big swapmeets every year so finding carbon bars, seatposts and such can be done at a savings. If you have those resources use them.

    The welgo wr-1 pedals with skateboard grip tape idea I stole from a member here work really well and even with the steel spindles can save half a pound over stock pedals - 28 bucks. Too small for adult feet but my kids like 'em.

    Biggest bang/buck re: weight

    At first I was a believer in the 2x_ setup, but eventually decided that ditching the front derailleur and shifter was free weight (n/a for your hotrock GauchoGreg). I also started looking for decent components like seatposts and handlebars that can be re-used on their future bikes.

    By far though, I think my best move was searching early and often--I got a great deal on Scott scale rc 24(22.5lbs!), and a sweet hot rock 24 that a fellow mtbrer passed on for a great price. I still have the urge to upgrade, but I think my wallet is much better off for having picked up bikes so close to what I wanted.

    From the German website listed on page 5 of the RST F1rst Air 24" thread started by Asmodeus2112.

    Took a week and a half to arrive.
