    Genes1s 24 Specialized Hotrock A1 FS rebuild

    So, this is Im sure nothing new for you folks, but its exciting for me. Im doing mountain biking because the kids love it. I would rather work on my car then riding but it changes a little this summer.

    My son is 9 and the 20 Cannondale rigid is too small now. I got this Specialized for a fair price and its a perfect excuse to build up the bike a little.

    So far I have installed Schwalbe Table Top 24X2.25 front and back, new front and rear Sunrace shifter (replacing the twist shifter), and Kool Stop pads.

    The bike handles so much better with the fat tires and my son is loving the new shifter.

    Next would be handle grips and inner tube.

    I'm tempted to do something with:
    1. The front fork, not sure if I want to go rigid, rebuild the current, or ? I've seen people use 26" rigid fork, or modifying 26" suspension fork, or just get a fancy 24" fork upgrade.
    2. Maybe taking the big chain ring to make it 2X7.
    3. Im tempted to go to disk brake also.

    If I go these route, I would just get new bike for the cost to upgrade.

    I do want to respray the frame since It can use some tlc.

    Decided to remove the fork and see whats up.

    Made a quick bike stand for $20. I know now why I bought the 20 ton press!

    Got the bike completely stripped, wire brushed the welds, acetone wipe and dried before sending it to powder coater

    Disassembled the fork and headset, cleaned, removed rust and polished the pin rod, and polished the stanchion due to slight pitting. I didn't use a new seal but cleaned it real good and repacked with new grease. Stripped the paint of the housing for gold paint.

    Got the frame back from powder coater this afternoon..loving it
    Satin black but with slight texture. They did an awesome job.

    Got a new stem for 31.8mm Handle bar and I polished the seat post and the V brake arms. Man...looks so much better.

    Assembling the headset.

    -img_4272.jpg

    Put new KMC Chains, new rear V brake post, new Kool Stops all around.
    The V brake rubber boot is dragging on the tire a little bit, I guess the tires have much more volume now that the clearance to the V brake cable is a lot less. We'll have to get new V brake arms but this will do for now. The powder coating definitely changed the look of the bike. This is probably the only time it will look this clean.

    I honestly didn't plan to go this far and I don't think this is a wise direction perhaps. I could've have gotten a used 2016-2017 bike for what I have spent on this bike but I'm super happy with the result and he's got a unique bike that he can use for another 2 years I hope. Looking forward how the powder coating hold up.

    This bike looks amazing! Nice work.

    Going disc-brake looks like a relatively easy future option since the fork and frame have mounting tabs,, but probably not "necessary" (as if any of this is). But you can probably pick up a set of entry-level used Shimano hydros on eBay for $30-40 and they'll work great. The bigger issue/cost will be new wheels, though.

    At this point I imagine the biggest weight savings opportunity/value would be a rigid fork. The 26" fork we put on my son's bike ("Beiou" brand) had an axle to crown of 415mm (I guess it was not a "suspension corrected 26" fork) which was almost the same as the spring fork's effective a2c. That dropped several lbs from the bike for around $100. But that specific fork is disc only. Of course the current spring fork certainly looks fantastic with the new paint etc.

    The wheels are actually decent. I could get different hubs and going for disc brake but I had to restraint myself from doing it.

    I looked at going rigid fork too and the Moroso ebay brand is about $70. I would be tempted to do this probably Christmas.

    Let's see how he does it. I almost certain he never going to use the biggest chain ring, so I was just going to take it grind it off and going 2X7 only.

    Yeah, I wrapped the front mech area and the chain stay with those plumbing silicone seal tape.
