1990 Diamondback Master TG find!

So pulled a 1990 DB Master TG that is nearly all original today. Pics will come later. I have a few questions:

1) What was the original saddle?
2) What was the original stem? This has a tioga prestige stem.
3) I need a longer stem, and my calipers will tell me, but what is the stem and make of centurion stamped bars?

Thanks in advance!

I had an Interval TG from that era. The stock stem looked very similar to the one on there. It was a black tig job. Guessing the saddle was an Avenir.

I had one of those, and could ride it one handed for blocks without a wiggle. Awesome frame! If you break a spoke on the wheels, just go ahead and get them rebuilt. Mine popped a spoke every ten miles until they were rebuilt. Never a problem after that.,,,BD

I have only seen one of these, and it had the same stem. I'm guessing it is original. Those stems are remarkably light and strong. There is zero flex. I have a couple that replaced alloy stems.

Nice pick up.

The wheelset is in excellent shape other than the rear needing a true.

That is what I assumed, need to see if I can track an Avenir saddle down. I am trying to find images or the catalog from the correct period.

The stem does feel nice, but is a tad short. I am going to have to track down one that is at least 100 ( this one looks to be about 80). I also have to find wider centurion bars to match if I want to succeed in keeping this all original. My other route is a black nitto stem paired with a set of nitto bars I have in the parts bin.

Nice Master TG. Make sure to post it in the show us your diamond back post. https://www.bikeforums.net/classic-vi...ond-backs.html

As these bikes you can tell are not to common, it might be tricky to find the right size stem and handlebars in the original components. i would just go with something else close you can find and archive the original parts for it.

It looks more like a 1991-1993. as there is not much information documented on the net for them , The Mountain Bike or BMX bikes ..yes .. road ..no. I posted in the thread mentioned above a 1991 Diamond Back Apex that has the same color scheme as yours.

All ive ever seen is the 1990 TG's had the same style paint as one of the color options the 1989 Centurion's had .

I bought it from the original owner who still had the manual (not that it is worth much) which said it was 1990. You are right on not being able to find a similar stem. Most of what I have found online are either really long or mountain stems in regards to tioga prestige stems.

Check the serial #

On my Japan made Master and Expert TG's, the first 2 digits I believe are year made.

My Expert had the same stem, and the one on my Master isn't original. The bars on the Expert were Kusuki Winpista.

Anybody have a 100 or greater prestige stem or black stem in general they want to donate.

I heard from a gentleman who sold these when they were new that centurion bars were rebadged nittos any truth to that?

Not sure about the earlier Centurions but the Ironman's bars were Nitto's

Nice, if the Manual had a 1990 print date, it was probably an early 1991 model . If i remeber right the manuals were alot like to today that they were generic and it could have been the same one since DB started doing Road bikes in 1990.

Are all nittos 26.0? All that I have had are. These seem to be 25.4.

It very much is generic, even covers mountain bikes. At least my last new bike covered one genre lol.
