Which is stiffer? lighter? more durable?

or maybe a FSA carbon track?



They're all around the $300 mark for the complete crankset, but I'm really looking at the first two.
Can anyone speak for these through personal experience? Thanks.

If youīre looking for durability forget the FSAs. Carbon dosnīt handle scratches well and the ISIS BBs donīt hold up very well and will probably be hard to get in the future. The 75s have a reputation for being very stiff but i doubt that you will notice a diffrence between the campas and the 75s other than appearance.

I think this stiffness thing is a real red herring. All these cranks are stiff to the point that you can't possibly tell any difference. Saying that one crank is stiffer than another or that you can tell the difference is like saying that one chain is stiffer than another. As far as durability, I'd expect the aluminum ones to outlive you, unless you pull and reinstall them every week. I don't like carbon cranks, and I don't like splined, and I don't like FSA, but that's just my own personal prejudice. I have Sugino 75 cranks on the track racer, and I find their quality to be exceptional. Never had any problems with them or the BB, they run smoothly and are extremely round. As far as weight, the carbon will be lighter than the aluminum cranks, but that matters little to me. More important is to get the excess weight off my body after a winter of overeating and underexecising.

All of those crank arms are very stiff. However, neither the 75s or the Campy cranks use a modern bottom bracket. Square taper is not and cannot be as stiff as a modern BB with a big fat hollow spindle and external bearings. However TTrackie is correct in saying that all are stiff enough and none of this will matter to you (beyond looks).

out of those, i would go w/ the 75s. But, the best choice is Omnium

I've owned the Sugino 75 and Campy Record Pista and unless you are putting out 1,800+ watts, you won't feel a difference (if there is one).

I hear the the Q factor (width of the cranks put the pedals) of the FSA is wider than some people are comfortable with.

Personally, I like Dura Ace.

PHR3AK

even a lot of track sprinters still ride square taper cranks, if they are stiff enough for them there good enough for about anything else. the bearings in square taper bb are a lot bigger than octalink/external bb so if you put a lot miles on them they might be be the better choice for durability too

id go for omniums.

also makes no sense to buy record pista/carbon cranks for a street bike.

Nuggetross

...grand mighty?

tgscordv6

Another vote for Omniums.

Record Pista - no question. All that new bottom bracket stuff is just marketing hype. Square taper Record Pista!

tgscordv6

Why do every road gruppos consist of external/splined bottom brackets nowadays?

Exit.

Hollow BB spindle=mucho weight savings for roadie weight weenies.

Weight savings... am of the opinion that they are still working to find a system that can beat a quality made square taper bottom bracket.

Have been working with an experienced frame builder, machinist, and mechanical engineer of who also raced professionally in the 50's and 60's, continues to compete, and at 75 he can still tear the legs of most people.

He has no use for external bottom brackets finding that most are very poorly made and tend to get damaged the first time you remove them due to the cheap materials used to make them... the tolerances on them are often very poor to start with.

He still runs on square taper bottom brackets and hits the curb at 270 pounds of muscle... he knows what he can and cannot break.

Sixty Fiver

Oh yeah... Sugino 75's for the win.

WoundedKnee

That bottom bracket is pretty.

wroomwroomoops

Must it be 144 mm BCD, or would a 130 mm do?

geist

Campagnolo.

Thanks guys, I think I'm going to go for the Record Pista.
If it's basically the same on the stiffness level as the Sg75, then the Campy wins for looks, haha

Also, is it important to have a nice chainring? More specifically, the teeth/ring design and material.
I hear that the chainring is just as important as the crankarms because it comes in direct contact with the chain.

I buy this, because I've personally killed an FSA Mega Exo BB inside of a year. All it took was 1 season of light cross racing and a Toronto winter to enable its "indexing." Also, the Alu that they make these cups out of is poo-soft.

I had that issue with a Sram BB for my old Ominums. Within a few months they started to develop quite a bit of play. Im riding Sugino R-D2 arms with a Sugino 103bb right now and its already lasted longer than my old Ominums did at a fraction of the cost.

Record or Dura-Ace will be my choices if I ever start racing and build a bike.

I was just asking this question except it included a White Industries ENO crankset, Truvativ Omnium, Race Face Decadence (the latter two being external bottom brackets). That FSA crankset looks cheap and looks like garbage although you'll find owners of it argue that point.

The simplicity of the Sugino 75 with the matching Sugino SG75 BB won me over. Although for wet weather, I'd go to a Phil Wood BB so you have sealed protection. Plus the Sugino chainring bolts and chainrings all match up to a perfect package. The Campy Record Pista I've owned before, such a gorgeous crankset (best looking, but does that need to be said?) matched to its carbon fiber bottom bracket, but it's $400+ so only for the ballers. The typical campy head, naturally.

The 75s have already won before this thread was ever made.

mihlbach

Thats correct. Sugino 75 is Gamera
