Crankset quality question: advice needed.

Assuming they're compatible with Shimano (and the noises I've heard are
that they're mostly all interchangeable, since really the interface
consists of a tube of a certain diameter, which is easy to match)
Is there anyone who ever tried this? I'm very curious if this is possible or
not.

Derk, I posted the following just above your 2 posts:
-----------------------
A coworker of mine replaced the OEM BB with an XTR BB on his external BB FSA
Gossamer crankset. He loves it and will probably go with the same BB next
time, also because it's cheaper.
-----------------------

I don't believe he needed any modifications to get it to work. I will call
him and ask.

Thanks Phil, I read it, but I don't have a FSA crankset, but a Truvativ
Elita crankset with external bearings.....

I too wonder if Shimano BB cups and bearings would work with Truvativ
GXP cranks, and I think not. The Truvativ cranks I've seen have two
different diameters where the bearings fit, but Shimano Hollowtech II
spindle is the same diameter for both bearings.

See this PDF for hints of the different diameters Truvativ uses. Clues
are the two different ID's of the left and right seals (Figure 2) and
also two different diameters can bee seen on the spindle (Figure 3).

Derk and Dianne, I found the following in a quick internet search:
-------------------------------
Like I said Shimano and Race Face external cup BBs will not work with
Truvativ or Bontrager cranks and vice versa.

Shimano and Race Face use the same standard. Truvativ is the same as
Bontrager. Which is not interchangable with Shimano or Race Face.

Bontrager is the same as Truvativ.

Truvative makes Bontrager's cranks.

Bontrager cranks are Truvative cranks with Bontrager decals.

Their (Truvative/Bontrager) cranks use different BB cups than Shimano and
Race Face.

When it looks too good to be true.............I already feared this.

Thank you!

Hi,

Could anyone tell me if the Truvativ Elita GigaPipe crankset with external
bearings is any good? I bought a bike that was advertised on the Internet
with a FSA ISIS drive crankset, but it came with a Truvativ crankset.
How is the quality of the Truvativ compared to the FSA? Will it last some
time? In other words: do I have to demand the FSA crankset or shouldn't I
complain about it?

I have a new Ultegra Octalink crankset here. Should I sell the Truvativ and
install the Ultegra or just use the installed crankset and when it fails
install the Shimano?

I have Shimano cranks on my road bike, but the best crankset I have ever tried
are my MTB Truvativ Firex
Wanted Truvativ for my road bike but couldn't find italian ISIS BB.


Lots of these 'out there'....Probably not MO, but most bike shops of a
decent quality will have them.

Those new external bearings should resolve some durability issues that splined
BBs had (both ISIS and octalink).
I think that integrated crank/BB are not that important but bigger external
bearings are great idea.

What gives you the impression that 'most' bike shops have a larger
assortment than the better MO places? It sounds like even people like
Harris and you need to go to QBP or other distributors for the unusual
stuff, and there are certainly ways to MO anything that the major
distributors carry.
