My latest score - not bad for $200 I think. My son is going to outgrow is 24" Islabike this coming season and I'd like to move him onto this. Not super rare, but slightly exotic for the day and for what I paid it doesn't owe me anything.

Overall a pretty nice survivor. MCUs in the fork are actually nice, but the wipers must be dry as it hardly moves. I plan to swap an AMP B3 on there anyway. It will also get new tires - probably some tan sidewall modern Schwalbes.

A tire changeout (470 gram Ritchey Zmax 2.1 repop tan-walls) , and about 50mm off the stock seatpost (it still weighs 270 grams even after the surgery) to fit my son and here's where we sit:

Not too bad considering the rear cassette spoke protector and even a bunch of reflectors are still on the thing. Judging by the seatpost and saddle, none of the stock components are very light. Initial goal is sub 9.5 kg I think.

Do you want to keep it period correct? Or just slightly retro?

First, I'd change the chainset, BB (I guess UN5x) to a tuned sq.taper M510 Deore crankset (full alloy rings&bolts) + a far east titanium (Brompton) BB = min. 250-300 gr. is shed, which is even better as it is rotating mass decreased! Fit long bolt type Allen key hub skewers: 50 gr. is gone. GS (short cage) M737/738 or M900/950/75X rear mech with alloy cage: 50 gr. is gone again. With lighter SPD (Crank Bros?) pedals another 100-150 gr. can be shaved also, I'm sure.
Light inner tubes as also a nice & cheap diet option, min. 50 gr./wheel. Oh, a modern, drilled cog 11-28t or 12-26t cassette can be useful too, with a proper, if not silly light chain (50-100 gr. minus).

Almost certainly it will end up as "slightly retro"

The wheels alone will probably rule out keeping it totally period correct as I'm a huge fan of tubeless and will probably end up using a set of Mavic Crossmax UST that post date the frame by at least a few years. I run these on my 93 Slingshot and it's a game changer for a bike that actually sees trail duty.

It's not like it's a super special or rare frame - and the ultimate goal is to have a nice riding, lightweight and reliable bike for my son - with an eye towards the period. Thanks for the tips above - I'll definitely be digging into my 8/9 speed parts boxes, which are largely XT range.

A little sad news from my recent contact with AMP Research:

--------------------------------------------------------------------
Hello,

Unfortunately, we no longer have any replacement parts for bicycle or motorcycle applications. When Lund International purchased AMP Research over five years ago, all of this inventory was sold off. The bulk of this inventory went to a company called JP Cycles.

If you have any other questions, feel free to email me.

Regards,
----------------------------------------------------------------------

JP Cycles is all moto - seems unlikely that they kept/took any of the bike stuff. Next step may be sitting down with a hardware/parts catalog and putting together my own rebuild kit.

Fork replaced and steerer trimmed (this knocked off about 300g), tires replaced, bar ends removed and seatpost trimmed a bit. Sitting at 10.5 kg (23.3 lbs) with heavy-ish stock wheels, tubes, controls and drivetrain bits left to go through.

2nd fork option arrived (it's only about 60g more than the AMP) and has cleaned and been sorted with nice soft elastomers (thanks rva) and soft green spring arrived from Dan Chambers. Also got some new old pedals, lighter bar and stem, and lost the spoke protector out back.

10.3 kg with the AMP and 10.36 kg with the M4.
