Early 90s Diamondback Centurion Expert TG


I bought this bike today for the frame fork. I don't like RX-100 so i stripped it and started building it up with 105 SC

It cleaned up real nice, the Maguire's polishing compound made the paint glow. I'll have it built up very soon.

Is that the orange with black line paint? Fantastic rider whatever the colour but I always looked for an orange one.

RX100 and 105SC are literally the same parts with a different finish and logo applied.

Bite your tongue! Or, er, fingers. That's not a Diamondback, that's a Diamond Back. One's from Walmart and the other's only ever been parked at one.

Nice bike, BTW. Love the paint.

This one is a Diamond Back but it was never sold through Wally World.

Had one of these BITD - very solid rider. Orange is never a bad choice.

How did Shimano literally make RX100 heavier by removing the paint?

105 has better seals in the hubs and ball bearing thrust washers in the calipers. RX100 is nice, but 105 is superior in several ways.

I built and sold these at the time. They really came off as road bike reinterpreted through the vision of a cutting edge MTB company - Tig'd stem and frame, MTB oversize tubing, MTB paint and graphics. These bikes were still WSI, but they were not Centurions.

I have a 1990 Interval, one of my favorite rides in fact, but IIRC it was already a Taiwan built bike. Lugged Champion No.2 frame and fork, great ride but I had to replace the uni-crown fork because one leg was 1/4" higher than the other and you had to fudge the front wheel when you put it in. It wasn't all bad though, I luckily found a an older style Cro-Mo fork that was a uch better match for the bike.

Yep, memory served me correctly........ .................................................................................................... the new fork crown, much more appropriate for a lugged frame.





With the replacement fork.
