At more than 13 kg this thing is a tank. My goal is to get it below 10 kg. Upgrades will include drivetrain, wheels, disc brakes, and cockpit.
Disc specific, 24" wheels, converted to tubeless.
Rims: Alienation Deviant 24x1.75, 28 hole, 415g Front and Rear = 830g
Hubs: Circus Monkey HDW CNC 6 Bolt Disc MTB Hub F&R set 28 hole = 392g
Spokes: Union Titanium, 2.8g x 28 = 78.4g x 2
Alloy Nipples: 16g (56)
Total: 1394.8g (not counting rim strips or skewers)
Tires: Schwalbe MowJoe 24x1.85, 330g each = 660g
Skewers: Circus Monkey Ti = 49g (set)
Cassette: Recon 11-36 = 155g
Stan's No Tube Rim Strips = 55g
Grand Total: 2313.8g
Approximate price is US$350.00 depending on ebay vs. retail availability.
What's better for a lightweight rider, air or coil sprung suspension? Air suspension is lighter but, as I understand it, is less tunable for small bump compliance. Coil suspension tends to be heavier, but I believe it offers a more supple ride.
In the case of my son, he is only 60 pounds, so I am trying to reduce the weight of his bike as much as possible while improving performance. But I don't want to sacrifice usable suspension for lower weight.
Anyway, right now it looks like only the frame will survive for the final build. I may stick with the fork if I don't find a better alternative. But used Rock Shox Sid dual-air forks can be had on eBay for under $100.00. I have found a couple of tuners who can rebuild the fork with 50mm travel, reduce the airspring to something appropriate for my son, and get the axle to crown length close to the 395mm of the current fork. Still working on a price though. It may not be worth it.
Drivetrain will be 2x9 (or possibly 2x10). I have most of the parts for that already. Just trying to determine if my sons thumbs are strong enough for trigger shifters or if we will use a grip-shift system.
The stock cockpit parts are steel (bars, stem, seatpost) and will all be changed for lighter versions. I have a carbon flatbar and several stems already. I might have to buy a seatpost.
I intend to switch to disc brakes. Avid Juicy brakesets are going as low as $75.00 on ebay. I just have to get something with adjustable reach for small hands. Wheels are discussed above.
I am confident I can get this bike down under 25 pounds. The only retail purchase I envision is the wheels. So I should be able to do this relatively inexpensively using parts I already have and a few good ebay deals.
Any thoughts or recommendations?
If kid likes riding, it won't have complains on a bike. Let him ride it the way it is and upgrade when you get good deal on parts.
Buy him SPD I missed that in my cildhood riding.
My son has been riding on SPD pedals for BMX and road the last 2 years. So that's a no-brainer for this build.
