Time to replace my Drive train, need some sugestions......
Moderator: robbosmans
You can get a chain checker to measure chain wear or with 3,000 miles on it you may just want to replace it. Dark colored chainrings look crappy after not too many miles. You may have a lot of life left in yours. It seems like your cassette should have lots of life left as well. I'd be inclined to fully clean the drive train and install a new chain. You can post some pics of both and the experts here will give you an assessment.

Are you sure...? I saw only for 3D30, 3D+ on their site...
L.E. You're right, there it is:

Honest LBS told you to replace large chainring with ~ 3k miles + demo miles? Let's be conservative and say demo miles ~1k. No mechanic in clear mind will replace chainring with such low miles unless it exhibit a defect.

LBS measure the chain and said I was due pretty soon.

If you are satisfied with what you own, simply upgrade to 6800. Alternatively you could price 6700 out replacement parts but with so many its probably not worth it, and 6800 is generally regarded as better.

Not quite, this is a 3D+, it has a 30mm axle not 24mm as the 3D24 has. It can be fitted to your BB86 BB but requires special bearings that are susceptible to premature wear.
The 3D+ or 3D30 with 30mm axle is what I'm currently running in my BB86 frame. No issues yet with my BB bearings and not expecting any. I'm using a Hope BB (4130) and its silky smooth, I would also look at Enduro Bearings a an option. The Rotor BB I have seems to have a lot of drag but I did not install it to check for sure, in the hand it is noticeably harder to spin.
I love the preload adjustment collar of the Rotor 3D30 cranks, so simple to use without the need for spacers. The inbuilt crank remover (collar) is also a big plus, all you need to remove the crank is an Allen key and cassette lock ring tool. The ability to then add a Power2Max later down the road makes it a bit of a winner. No need to send it off for installation or purchase another crankset. It's simply spider off and power meter on.
My only negative to the system was the older graphics, the newer models are much more subtle. If you're so inclined a quick spray black would have them looking bad ass on that bike.

So if the chain is just getting the verge of needing replaced...........unless those demo miles were something on the order 15K miles......and unless the pictures of the teeth show otherwise, me think the mechanic is looking to sell you something you don't need yet (chainring). By my experiance, if you care for your chain and replace before it's toast, you should get something around 3 - 4 well worn cassettes and double that number of chains before you should need to replace chainrings.

i upgraded most of my cpt's from ultegra to dura ace. believe me the grams don't translate into any real performance gains. what you might experience is smoother shifting and better looking equipment(depends on your taste).

You can see some of the top of the teeth wore off. Not sure if that's why he said I could be replaced soon
This LBS let's you bring your own parts so I don't think he's just tring to sell me stuff. More so that he's picky and prefers bikes in top condition when you can.
