Cranksets: DA vs Record/PW.
 

I'm thinking it is time to fix the borked stock chainline on my '11 Steamroller by replacing the stock Andel double crank with a proper single one.

This bike is a daily driver. Commuting/Utility, rain or shine (though it mostly shines around here), I'm also heavy, 230 pounds +.

I've narrowed it down to:

Campy Record Pista with a Phil Wood BB

or

Dura Ace 7710 with matching 7710 BB

Cost is about the same, either way, so price is not a factor. Any strong reasons to go with one or the other, or is this just an aesthetic choice?

If you have to get one of those two, my vote goes towards Campy but I am biased :O

Although, the Miche crank is pretty nice.

If you go with DA, I'd advise against the 7710 BB, and say you should get the sealed ultegra BB. They're the same measurements, 109.5mm.

I ride DA and love them, but would prefer a sealed BB. (which I have, just gonna do it on the next frame)

From everything I've read, they both of the same caliber, so it just boils down to aesthetic preference. I think there was a thread asking this exact question a week or two ago.

Does the Phil Campy BB require a special tool to install? If so, it might be something to consider.

(DMX) Here we go again!

I'm surprised to see you listed phil wood there. Anyhow, Dura Ace is handsdown your best bet out of them all.

Yup, flip a coin. They perform the same.

He's only talking about the Phil BB, not their butt-ugly track crank.

miche cranks are sexy

7710 BB's are sealed.

Oooohh, yes I'll admit that I was treating this thread as if it was one of those threads again...

Anyhow, owning BB's from both makes, you can't go wrong with either as far as quality and performance goes; you're obviously getting what you pay for.
Installation of both require proprietary tools nonetheless.
I find campy's more traditional 2 piece cartridge BB to be easier to install as I do not have to fiddle around with philwood's standalone cups (3 piece cartridge BB design) which are very narrow and easy to cross thread in a BB shell if not careful. From experience the blue locktite provided with the philwood BB cups are there for a reason use it no matter the frame material! I've found my BB cups vibrating loose from riding w/o locktite on my steel commuter.
The flip side of philwood is that you have more replaceable parts in the event and wider chainline adjustment/ fine tuning/ leeway with the cups having no predefined limits/flanges nor having to use spacers.

listen to the man who owns both of them ^

They aren't. It's some odd cup and cone thing with needle bearings. They might be "sealed" with an O ring, but its definitely misleading.


A 7710 is just a 7700 with an NJS stamp.

^you can get them for the same price... makes sense.

also the 105/5500 is 109.5 as well and I may or may not have one available... *whistle

nos?

The only reason why I am looking at the phil wood BB rather than the record BB is that the latter is reputed to be less than weather resistant despite being a cartridge BB. Whatever I get needs to be able to handle anything from monsoons to dust storms.

I have not had the balls to weather test any of my newer campy BUT I can back up the latter remark about phil wood BB's. There's a reason I have one on my daily commuter mated to SG75's which sees rain and daily lock ups with zero necessary maintenance on my end except/post loctite application to cups for some 1000+ miles and counting day in and day out.

Those pdfs only describe the 7700 and a 7703, no mention of the 7710. Actually I can't find any mention of the BB-7710 on their site at all. Everything else I've seen indicates the 7710 has cartridge bearings. But I am not averse to an Ultegra or 105 BB if that is a more durable choice.

Proved me wrong. My bad.

go for it.

No worries. Better safe than sorry. I've been giving myself a headache trying to figure all this out.

Well I gotta say, I've been more than pleased with my DA setup.
It really comes down to aesthetics, both are sealed BB's so weather won't be an issues, and both are of the same performance level to the average person.

Pick the one you think looks best.

I would not put either of those on a steamroller.

All City 612.

From seeing this thread come up a few times, the answer usually ends with the following:

If you're using them for the street and recreational use (i.e. not track) you won't notice a difference with either because you aren't producing the kind of track racer torque that they're designed for.

Both are top shelf stuff and you should make your choice based on looks, ease of installation, or whichever will make you feel happier.

(To qualify this, I haven't tried either crankset. I've just read this discussion a number of times and there never seems to be a clear winner)

like I said, someone here has used both, and he says there is a clear winner. I've also never seen a set of records at our track

7700 has needle bearings.
7710 has sealed bearings.

I've owned both.
