Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Paying the price

So the person who put my bike together managed to do a really bad job. Now that I have put on around 3000+ miles I need to replace a bunch of stuff...sigh At least I found a good mechanic in a shop that is about to open so I am getting a deal.

1) Bottom bracket and spindle shot, apparently it wasn't tightened enough and both bearings are shot and there is a lot of play.
2) bend rear rerailuer (my fault... :-) ) the hanger is straight. The derailer in the big ring touches the spokes.
3) Headset spacers are the wrong size....
4) chain is worn out

So My list of new stuff is:
1) new compact carbon cranks and bottom bracket (supposed to make it stiffer and lighter); whatever that means
2) new 105 deraileur with a short cage
3) new spacers
4) new chain
5) major tune-up

Labor was knocked down to almost nil....

He said at some point I should upgrade my handlebars to carbon for better performance. What is the advantage of carbon handlebars?

"Stiffer" implies that the crank set / bottom bracket won't flex as much when you're pedaling all-out. The likelihood that you're putting out enough force to significantly flex virtually any crank arm is pretty much zero. The "compact" part... There's been about a million threads describing what compact cranks are.

chain is worn out
Be aware that if the chain is badly worn out you'll almost certainly need to replace the rear cassette as well. Otherwise, the chain and cassette won't "mesh" properly and the chain will slip.

They lighten your wallet and thus enable you to go faster as you aren't carrying around as much weight. Seriously? They're usually slightly lighter then their aluminum counterparts. Some claim that they help absorb the vibration from the road and thus give you a more comfy ride; I personally think you could get the same effect by choosing plushier handlebar tape or different gloves.

I don't see how can you blame 'the person who put my bike together' after riding 3000+ miles. All your points (beside the headset spacers) are part of the regular wear and tear. Headset spacers size is relevant for fitting, if at all.

Carbon bars? They weigh about as much as aluminum bars. And they cost a ton more.

Example:
Ritchey WCS 31.8mm aluminum bar: $45 and 235g
Ritchey WCS 31.8mm carbon streem bar: $210 and 230g

I lol'ed after reading that sentence. Carbon handlebars are probably one of the worst price to performance upgrades you can get. Somebody's got a few too many sets of handlebars lying around the shop. The two bar sets mentioned above illustrate to ratios quite nicely.

cool, thanks for the input. To clarify, he wasn't pushing me to get it now, he was mentioning that might be interesting to upgrade in the future.

Are you sure that your new mechanic is trustworthy? Something sounds weird here.

1) Compact crankset isn't something that should be purchased based on being lighter and stiffer. It should be purchased because that gearing would better suit you.

2) New derailleur, in no way previous wrench's fault.

3) I've got to know, how could the spacers be the wrong size? Either they are 1" or 1 1/8". They aren't exactly interchangable. You may not be sized exactly right on the bike but that changes as you ride as well.

4) A new chain is pretty standard at 2,500 - 3,000 miles.

5) Tune up pretty standard as well.

6) I'm sorry, I just have to laugh about the handlebar upgrade.

Now, as for the bottom bracket bearings. These days with ISIS and Octalink it isn't uncommon at all for bearings to wear out early. Heck, my external bearings on my Campy Chorus crankset are going to need replaced soon and they have less than 3,000 miles on them.

Honestly, from what you describe I don't see any proof that the person that built your bike did anything wrong. It sounds more to me like the new shop is just trying to take the other shop's customer.

Lighter wallet for you, more money for him.

I think that I must have misunderstood some of what he told me. I do actually trust the mechanic as he works for one of our team sponsors.

To recap:

-Get compact cranks ONLY if you need the gearing
-Carbon bars add nothing
-You might want to get a new cassette with your chain

I'll add:

-Consider not going back to this shop (the one suggesting the carbon "upgrade")

Dave - I assume this guy works for a bike shop - or just a buddy of yours who stands to gain nothing in terms of $$ if you buy an expensive carbon bar or a cheap alloy one?

Also, "Woodinville Guy" kind of sounds like your from the Seattle area - as am I (about 30 minutes north of you in Lake Stevens). If this bike advice came from a bike shop, which one?

And yes, I agree about the waste of $$ of the carbon bars. Also, I'd say forget about going with carbon cranks, too. They might be measurably "stiffer", but not to the average joe or even somewhat hardened cyclist. A hard-core racer could probably notice a performance difference, but you could save a pile of $$ by going with a good ol' Shimano Ultegra, SRAM Rival, etc., get a crankset that's plenty stiff enough for the pro's, and save a bundle of cash in the end.

I'd agree with the comments above regarding carbon bars and cranks. Carbon is a good material for frame and fork....given it's failure mode I don't think it makes much sense for handlebars, cranks or seatposts.
