Good morning community. This is my first post here.
So this is my bicycle, from year about 2004 or something down there. I would like to make some improvement but it might be too pricey. I would like to put a more modern transmission: now it has a triple chainset 22, 32, 42 - as it was common back then - and a 8-speed rear cogset 11-30. I'd fancy a more recent thing and also a rear disk brake. So it means I should change the whole transmission, put a shorter freehub suitable for the disc, put the right spokes and so on. It's not urgent, but I'm thinking about it and I'm afraid of the cost of all these things.
Apart from that I'm having a really good time and I'm fond of this bicycle.
Sorry for my roughly translated technical words
Disc brakes are the one thing that you really can't add to a bicycle that wasn't made with them in mind. (I know there are adapters, but I wouldn't trust them.)
Like others said, probably time for a new bike.
Disc brakes aside, you'd have to upgrade the whole drive train and the wheels to get a modern groupset. Even buying used, you'll put quite a bit of money into that, even if you do the work yourself. And while you're at it, you might as well replace the bottom bracket and headset bearings, which aren't that expensive but are an added cost. You'll probably need some tools you might not have too.
Groupsets are ridiculously expensive for the average consumer to buy. The bike manufacturers buy in bulk and pay way less. That's how they can offer bikes so cheaply.
Yes I forgot to mention that my frame already has the placement for the disc brakes, but the wheel hasn't. About the rest, I sadly agree
Oh I zoomed in but didn't see the mounts on the frame. Obviously the fork has them.
