8 speed longevity

I am in the process of upgrading my bike. I am quite happy with my current 8 speed set up. I have some brand new parts to do the upgrade. I was wondering if anyone had any input as to how long quality 8 speed parts will still be around. I noticed that Sram seems to still support 8 speed. A good sign.

Honestly, I don't think much longer. 8sp is coming up on 10 years old now, just try to get 7sp stuff which was really only 3-4 years before 8.

In about 2 years it will go the way of the dodo, IMO.

Well, 8-speed has one big thing going for it: 8-speed cassettes fit on the same freehubs as 9-speed and 10-speed. If it won't cost you much extra to upgrade to 9 or 10 speeds, do it. But otherwise stick with 8 - there will always be stuff on eBay.

Campy 8-speed components are getting very difficult to find and are reaching collectors item status.

Shimano is doing a bit better. Chains and cassettes will be available for quite a while but shifters are getting hard to find. I've got 8-speed 105 on two bikes so I'm aware of the growing scarcity first hand.

Fortunately, Shimano 9-speed hubs and derailleurs will accept their 8-speed cassettes and work fine with them.

The difference with 8sp is that it uses the same frame, hub spacing, unlike 7sp. I have no interest in 9sp. The overall gear range doesn't change. I think the continuous movement toward more gears is so people think they have to keep buying new parts, and shimano gets richer.

Well, Campy made the first move to 10-speed so Shimano isn't the only one trying to get richer.

Yes, the constant changes do obsolete parts and eventually you have to upgrade since you can't replace the old components. However, I have found the increase from 5 to 6, 7,8 9 and now 10-speed to have given me a continually better choice of cogs while allowing me to increase the overall range. I can get a 13x26 Campy 10-speed cassette that is a straight block from 13 to 19T and still gives three lower gears. A 6-speed freewheel/cassette with that range has some huge holes in the internal gearing.

If you want to keep your 8 speed running, the time is now to start stockpiling spares. I've got enough spare cassettes, chains and shifters to last me the next 20 years.

Yeah, I thought this was a mtn bike question. On a road bike I can understand more than 8. If I remember right, campy just about skipped 9 and went right to 10 to beat shimano.

+1. I just bought a bit of XT 8s gear for a really good price for the sole reason that I want to stay on 8s on the MTB. It is an old bike and to move it to 9s seemed a bit wrong somehow. I think 8s stuff will be around for a bit longer yet, but definitely do what Svr says, stockpile for your life!

Here's a related question: since many people have reported that Shimano 9-sp brifters eventually fail and are not rebuildable, I anticipate having to replace mine eventually. Any chance I will actually be able to buy 9-sp Shimano brifters in the near future, or will I be forced to upgrade to ten-speed?

+2. I have five 8-speed bikes in the house. With the arrival of a new frame, I'll soon be building up another 8 speeder - I have that many 8 speed parts/spares, mostly new, lying around. So stock up, no real need to move to 10 speed today, absolutely no benefit to go to 9.

The shifters will be "available" for a long time but will get harder to find and be more expensive. Currently they are a bargain since they are relatively recently been made "obsolete". The longer you wait, the worse and more expensive the situation will get.

If your 9-speed brifters fail, you might as well upgrade to 10-speed since the only other components you will have to replace are the cassette and chain.
