So in between deciding what to do with my second Straight 6 build, I chanced upon another of my dream bikes, an AMP Research B5 on the 'bay for a reasonable price and picked it up because it was in my favourite colour of yellow:

Image

Knowing the amount of bespoke parts that accompanied those early full suspension and disc braked bikes, I also picked up a 1999 Mercedes Benz MB4 that would serve as a donor for the important components - such as the brakes, brake mounts, hubs, and possibly the fork. The MB4 I got was an interesting bag of bits - it looked to have been ridden only on pavement, suffered a bunch of chips that looked like they came from bike rack and handling rather than trail riding. It wasn't completely factory spec, some of the original bits, as best as I could tell, have been swapped. But the important parts remain, as I intend to make it look like the catalog bike:

Image

And here's now the MB4 looks like. The B5 is in the mail......

Image
Looks like it had a fairly easy life pounding pavement instead of dirt......

Image
Some parts, like the M755 rear derailleur, as well as LX crank, look like they've been switched out. No matter, M95x XTR bits will go on there. The saddle has to go.

Image
The seat mast has more sheetmetal than the AMP version - I prefer AMP's.

Image
The AMP brakes use a fairly small rotor, and is a 3 bolt pattern. They bolt onto a standard Shimano XT M737 hub. How, you may say?

Image
A disc brake mounting ring is secured to three of the spoke holes, and the spokes themselves are laced onto this ring as well. Viola! Disc brake hub.

Image
This is the F3 fork, but for the B5, I hope to be able to get the F4BLT to match the longer rear travel.

Image
A lot of CNC machine work

I've moved it along a little:

Image

Image

Cockpit:
Raceface Ride stem (just because it was lying around, I much prefer a Kore to be correct)
Easton CT2 flat bar
Shimano M950 8-speed XTR combo brake and shifter
Chris King NoThreadSet (just dummied on for the pictures)
Thomson Elite 31.6mm diameter 287mm long seatpost
SDG Ventura Comp Ti saddle

Drivetrain:
Shimano M952 chainset and bottom bracket
Shimano M952 rear derailleur
Shimano M950 8-speed cogset

The final items to be obtained for this build:
Kore or ControlTech stem
AMP F4 BLT fork (the F3XC fork currently on the bike probably would not match the rear travel well)
Risse rear shock (the stock AMP shock on there now is leaking)
Some fancy skewers to replace the horrid cheap items on there now
Better spokes, rims and tires (eventually) as they are now mismatched budget items

Excellent work, looks brilliant. I was impressed with the Mercedes as it was, but the AMP looks amazing. Definitely agree that the AMP seat mast looks better, matches the fork well too. Keep up the good work.
