Need help understanding my frame

Not sure this is where to post this so tell me if I'm in the wrong place.

I am trying to find a touring bike that has all the components I want and without breaking the bank I think I'm going to have to do a number of component changes on whatever I get. I do have an old diamondback ascent, 1989 I believe that I realized may be a good starting point but am not sure. I wanted a steel frame which this is with 26" tires for international ease of replacement and it fits me already.

It says on it it's 100% true temper AVR double butted CRMO tubing. Is this a good starting place for such an old bike? I would have to upgrade the cogs from 7 - 9 to get the granny gears, maybe get new wheels for strength, new stem - has a little rust and new handle bars so is that frame worth updating with everything I would need to upgrade?

I see no rust on frame. I think I paid about $600 for the bike when it was new so wasn't a real high end bike.

Its a good basis .. https://www.retrobike.co.uk/gallery2/...nt+EX+-+Part+2
Pre suspension fork MTBs make good pannier carrying Touring bikes

get 26-1.5" tires for street riding and adjust the bar reach to be comfortable

Ergon Broad palm supporting grips are Nice, saddle choice is personal People seem to have bought a Lot of Brooks leather saddles

and Pedals are another hot bed of discussion platform pedals and comfortable shoes are fine.

No need to go into more complexity Its the gear ratio that moves the bike .. I toured dozen+ countries in Europe + the british isles

with a 13-34t 6 speed rear cluster and a [50,40,24] triple crank.. I widen the range of gear ratios rather than add a Bunch of slightly redundant gears in the Middle

But Marketing wants you on the latest Stuff .

Resist or Submit..

7 speed Shimano's K cassette was pretty near perfect .. IMO.

There's no reason that this old frame won't make a fine touring bike. The first thing though is not the bike so much, it's the fit between you and the bike. Is this good, comfy for hours of riding? Only if how you posture on the bike (reach to bars, shape of bars, "drop" to bars from seat) is good would I suggest you spend any effort on this bike.

26" wheeled touring bikes make a good choice for heavy loads and less then smooth roads. Wheels and tires are widely available in many grades and capacities. Next is the bike's ability to carry a load. rack (and fender) eyelets and bosses make for a far stronger rack mount then the brake boss and QR skewer mount racks do. But the latter work well enough for many too.

After this the rest is just money. Andy.
