Yes, I figure it's a '91 as well. It says "Centurion" on both the bars and the chain-stay. Shimano Exage 500, nothing special. I'll post a few more pics after I clean it up a bit. I like it a lot, that's all that matters!

Cool looking forward to seeing it, the 1990 Diamond back Logo was a little more understated, So its probably safe to say its a 1991 (until someone has Diamond Back catalogs we could compare to)

They call me Mr. TiGs
Master TG shortly after I got it a few years ago. Serial # says '89 but may have been an early '90 model. Recently acquired an Expert TG, but no pictures yet. Serial # on that one says '90. Frame is the same with black smoke instead of grey.

Here is my 1990 Diamond Back Topanga that I bought new as a commuter and trail bike in college. I use it now to ride around the neighborhood with the kids.

Nice Master TG, The Serial number may give a 89 build date for the 1990 Model Year.
The Diamond back road bikes were started in 1990 after the parent company WSI, Discontinued the Centurion Brand in 1989.
Post the Expert when you get a chance please!

Fork: 100% chromoly steel. The front fork has low mid-eyelet perfect for touring.
Sizing: The frame has 16 1/2" center to center seat tube, and 21.6" center to center top tube. 29" standover height.

Second up is my:
1994 DiamondBack Apex
Size 20"
Frame: super light True Temper TT-Lite chromoly (CrMo) steel
Fork: 100% chromoly steel
Sizing: The frame has 19 1/2" center to center seat tube, and 23" center to center top tube with 30.5" standover height.
Components: Shimano Deore LX gruppo. Bontrager compact crankset, 42/32/22. Front and Back wheels are Suntour XC Comp wheelset.
Current weight is 26.1 lbs as shown. With lighter tire and regular tubes instead of heavy duty thorn protection tubes, it will be in the low 25lbs range.






Sadly as part of spring clean up, both bikes will be put up for sale in CL.

Well, I didn't even know this thread existed. Here is what I am told (considering I was given the owners manual with the bike) is a 1990 Master TG. It was all original except for the pedals (dura ace clips) and the seat (need to find what the original one would have been). This guy has had it hanging in his garage unsed for years. More pics after I get it cleaned up. I took off his gel saddle with a gel seatpad and put on an old san maro until I find something more fitting period wise. (and if my butt likes what I find)





Looks like it is a 91

Thanks for posting the Master TG,
It looks like the wheels are original, what are the wheels and Hubs?

Diamond Back Ascent, 1987ish. Not much noteworthy. Rattlecan invasion stripes on seat tube courtesy of yours truly. Ended up giving it to a kid next door who needed a bike. I hope he thrashed the hell out of it and had a great time doing so.

The Diamondback you see most around here, this one in the back yard. Almost 6 feet. Picked him up with a hula-hoe and dropped him over the back fence so he could go live his snakey life. "Go be a snake, old man."

Yup. Actually I ended up settling on 18" Cimarron as my Cyclocross/commuter ride and 18" Specialized RockHopper (in progress of being converted to drop bar) as my ride when I visit my dad... I have been taking my bike whenever I visit my dad in LA, 350 miles each way. I am still debating on what to do with the 21" Cimarron though.
