I have a Diamond Back Ascent EX circa 1993. I got it as a 30 birthday present from my wife. I'm now nearly 50 and I'm figuring out whether me or the bike is wearing faster!
It came with an Exage ES groupset. It's original apart from the BB/Crank/Cassette (i.e. brakes, derailleurs, hubs, shifters). Over the last few years I've been constantly trying to get both sets of gears to work, but they keep slipping between gears, not traversing all gears and various other problems. Finally, I took it to a qualified mechanic who said that the trigger shifts were worn out and it would cost a fortune to repair the bike (saddle broken and rims going fast as well). I guess given its age other things could be worn as well.
Trouble is I love the bike. It is pre-suspension (!) and I've got so used to it.
Can anyone advise me on either how to replace the componentry? I've looked on eBay but Exage ES stuff are like hens' teeth. Is there a more modern upgrade I can use? It is a seven gear cassette at the back and three at the front if that helps the youngsters!
All advice gratefully received. The bike has been a faithful friend for so long I can't bear to see it go.
Many thanks for the help.
