components... worn or not worn

clod71

I know it's a stupid question... What is the life cycle of groupset, specifically a Shimano Tiagra?
I tried to keep it clean and I treated it as well as I could for the last two years. It has now about 9k and chain and cassette have already been changed once.
I think the front mech is starting acting up a bit and maybe the cables will have to be changed, the gears tuned, brake pads, ...
Does it make economical sense to keep going like this or I'm better off going for a new groupset?

Thanks for any tip you might want to share

If you keep changing cassette and chain (and cable), you should get years and years out of the rest of a groupset -unless something dramatically breaks, your derailleurs and shifter should be fine to keep going... most people only upgrade because they change bikes or have too much money to spend -cables are cheap and if it works ok after you swap em out, then happy days!

I bought a Tiagra equipped bike in 2000. It has a lot of mileage done at this stage. Of the original Tiagra it has the shifters, brake calipers and front mech. The chainset is on a different bike although its inner ring is new. Everything wears and needs replacing at some point, I'd guess the quickest wearing for me would be chain, brake pads, cassette, bottom bracket, cables, chainring in that order. The rear derailleur doesn't last too long when you fall and it gets mangled in the rear wheel, I replaced that with a 105 and it didn't change the bike one bit!I had to replace the jockey wheels last year as they became sharply pointed.

I also have a Dura Ace 7800 bike of 5 years, same things need replacing, last night I changed out its bottom bracket. It's starting to get "sluggish" in its rear shifting so it's probably time to think about the gear cable.

I seem to go through a lot of rear mechs. They all seem to wear out fairly quickly. I've gone from Sora to Tiagra to 105 over about 4 years. That said, the bike is out in all weathers so road dirt presumably takes its toll.

Sounds like I'm not going to get a new groupset then... Going through new cables and a bike service maybe will mute those rattles and squeaky noises. Maybe I will just upgrade the front mech.
I will have to learn to do the cables myself one day, but maybe not just yet...
