Is it worth it?

Is it worth it to change the two derailleurs, shifters, cassette etc instead of buying a new bike for around $500? Was thinking about Shimano deore parts. Trying to save some money.

I would think it depends at what price you can get replacement parts? Did you try google, ebay as a starting search? All of the parts you desire are out there.

I did this to a bike of mine, while I wasn't to fussy about parts - I upgraded a 24 speed to a 27 speed because it ended up being cheaper (well marginally more expensive short term, but cheaper long term due to other parts wearing out/failing) to replace the entire drive train (chainwheels, cranks, cassette, f/r dérailleurs, chain and shifters) than to get the obsolete replacement part I needed.

It all depends on how much you value the rest of the bike, and what deals you can get on the bits - I got some very good deals of a well known auction site and a rummage (reduced price) bin in a local chain store.

Personally, I wouldn't bother unless the parts are already worn out. Chainrings tend to last a bit longer than cassettes, which in turn tend to last longer than chains. Just replace parts as they wear, unless you're looking specifically to change the setup. BTW, a derailleur will generally shift whatever number of sprockets you ask it to as long as the cable pull is compatible with that of the shifter, so there probably won't be a need to replace that even if you're changing the sprocket count.

Pricepoint has a SRAM X7 build kit for $239.98. That's a hard to beat deal. http://www.pricepoint.com/detail/192...d-Kit-2010.htm

The frame and wheels are steel in good shape, but just that it's an old model and that it comes with 26" rims.

Hi ChowChow!

Do you have any salvageable components?

Are you sure you need to replace all of the ones that you've listed?

More of an upgrade than a fix.

I just want more speed and upgrades in components instead of buying a new bike, if I can get away with it. Being that if I can save a lot of money.

Well, if I upgrade some of the components. The new components may not be compatible with the old one etc. The current components on the bike are still in fair conditions.

That is a great price, but is Sram brand good or as good as Shimano?
How does it compare with Shimano Deore?

Sorry, but I'm still kind of new to bike components etc.

A few years ago I switched from Shimano XT to SRAM X7 and preferred the shifting on the X7. Like all things others will have a differing opinion, but I really like SRAM components.

And it depends on how much you love the bike for it's own sweet self.

Hey there ChowChow!

If I were you, I'd dismantle the bike and have it powder-coated. Next, I'd get my wheels nice and shiny (like new). I'd replace the casette, the derailleurs, the chain, and the shifters, all at one time. If on a budget, I would wait to replace the handlebars, stem, seat, and seat post. Perhaps, one per month or so.

When you're done, it will be like new! It would have also been a lot of fun!

That's the greatest thing about chromoly, you don't have to worry about your bike pooping out on you, just after doing a bunch of upgrades! You'll essentially have a brand new bike!

- Slim

PS.

Go for it!

I really like what this guy did to his 1987 Schwinn Sierra. I got the exact same one. With the same colors etc too.

You'll have to scroll down a bit to see how it turned out.

That's a really nice bike, huh?

How's the paint holding up on yours?...Does it look anything close to that vintage-retro-classic Sierra we linked?

Same thing. Maybe just a little scratch here and there, but the paint is holding up pretty well.

Oh Boy!!!

If I were you, I couldn't wait to get started!...Man!...Are you LUCKY!

That means you can just skip the paint-job altogether, and go straight for the upgrades....
