Shimano FC-6800 Crank
Postby Newcastle Dave » Mon Jul 24, 2017 1:22 pm
Having removed it, I cant quite figure out how its all put together (much to my mechanic fathers shame, I am a mechanical klutz). I can see four bolts (stupid star bolts, what's wrong with hex screws) seeming to hold the pedal "spider" to the chainring, but these seem to be done up without any movement.
Is that all that hold the two pieces together ? (need to go shopping for a large star driver - anyone know what size these are ?)

Thanks Duck - so if mine look like this (hoping image displays) then I guess it is stuffed.Duck! wrote:The T30 Torx bolts only hold the chainrings on. The crank arms & spider are hollow, each made in two pieces and bonded together - you can see the join all the way around the edge of the inner piece. The large chainring is similarly made in two pieces and bonded together. It's uncommon, but there have been cases of the cranks and rings failing at the bond.

Rang the LBS that I have had previous good dealings with, they quoted $580 but said they had none in stock, nor did Shimano have any listed in Australia.
So looks like I order one from OS (and save heaps)

Nah, its 3 1/2 years old, but only about 18000 km - must be the awesome power I am putting downDuck! wrote:Yes, that appears to be a separating crank arm/spider. It's kaput. If it's less than two years old it will be covered under warranty.
So how come Wiggle can sell me one for $205 while the LBS says they are over $500 ?

Newcastle dave- Shimano don't have a spare parts division. They have nice offices instead. Buy it from wherever you need. 18,000kms - was getting time for new rings anyway. So buy a new crank, chain and cassetteLukeyboy wrote:Jason. Geoff...Newcastle Dave wrote:but said they had none in stock, nor did Shimano have any listed in Australia.

So I asked them;
1) Why do Shimano not have any stock of this in Australia ?
2) Why is the Australian wholesale price close to 150% more than the retail price overseas ?
They replied
"With Ultegra 6800 series being phased out to make way for the new R8000 series, we have limited availability of remaining FC-6800 cranksets.
Meanwhile, overseas retailers may be quite heavily stocked up; hence their low prices to clear out previous generations and make way for new components.
We are expecting some specifications new Ultegra FC-R8000 to start arriving this week."
I then asked them if they thought running out of stock of the old component before stocking the new component was their idea of good customer service (I told you I am an old cranky bastard)
They then replied;
"Actually, I’ve just had a look and we just have literally just received FC-6800 in 172.5, 52/36.
Meanwhile, the new model FC-R8000 is available and actually a few dollars cheaper than the 6800 model."
I bet its still a lot more expensive than I got from Chain Reaction

What is true though is that 6800 will become harder to get as it's phased out for R8000, given the cross compatibility between the two groups.

It started before the phase in of the product. Easier that wayLukeyboy wrote:Must have started that phase out back in 2015 haha.With Ultegra 6800 series being phased out to make way for the new R8000 series
