TA Carmina BB recommendation - Atlantis

[Mitch Browne]

I bit on the TA Carmina triple posted this weekend.

Of course I don't need it and am very happy with the Sugino XD 48/36/24 Tange 107 BB on my daily commute Atlantis.

I've looked at Peter White's website but don't readily find a Phil to fit. I do see an SKF on Compass.

Any length suggestions for a Tange or Phil BB that would best fit this crank on an Atlantis? Offset advice?

Thanks,

Jeez Mitch if you don't need it you can always sell it to me (beings
how I was late to the party) and save yourself the trouble of
searching and finding other things you probably don't need. Just
trying to help.

Hey Mitch,

I saw this post as I was searching for folks experiences with carmina cranks and SKF BB's. I am thinking of buying a used carmina on here and pairing it with an SKF BB and I just wanted to know if you ended up going that route? I read Peter White's carmina info and it seems like a 110 mm would work best for the double I'm looking to setup, and he says it should be 10 mm more for a triple, so I'd be curious to know what you have.

How do you like the carmina? Happy riding and thanks for your feedback!

I have a used but perfectly fine Phil Wood 119 mm BB, if you are interested.

Mike,

I didn't really give the Carmina's a fair chance. I installed them a rode to work twice. I was very happy with my Sugino's and use the triple daily so went back to those. I used a 116 BB but noted that 120 would be better. The one Michael is offering would work fine.

Cheers,

    With the Latest version of the Carmina 24/36/48 Triple on the Bombadil I used a 115mm Tange which is the length that Bilenky recommended .  I'm pretty sure I used a 1 or 1.5mm spacer on the driveside.

Pete White's recommendations are based on PW BB's, which I believe the taper sits just a hare deeper into the crank arms than Tange.
Here's someone used a SKF BB with a Carmina Triple on a road bike and used a 110. With the Atlantis,  the 113 or 115 would be fine.  SKF's are adjustable too for chainline.

I would recommend calling/emailing RBW about this. My recollection is that they spec relatively short BB's for the Atlantis because somehow the design/length of the chainstays creates more room than you might expect on a trail/tour-type bicycle.

Agree.  Went through something similar myself this morning with my Atlantis and an attempt at a different crank set and got immediate clarity with a short phone call to Mark at Riv.

I'm going to contradict myself and say I think I may have used a 110 Tange w/DS spacers with the Carmina triple .... lol.   I cannot recall for sure !  I sold them a while ago.  I'm pretty sure RIV has not had experience with Carminas btw .... I believe I did ask them prior to getting mine. But who knows, maybe that's changed. 
Yes, the Atlantis, like the First production Bombas, can use 107/110 BB's with 24/36/46 or 48, but no larger rings than that .
This what my Bomba stays look like :

And really, I found it best to simply invest in a number of sizes of cartridge BBs to have on hand to test with .  I don't recomment the Shimano UN-54/55 as they have a lid on the non DS cup that does not allow for DS spacers and the slight shift in the cartridge in the shell. Tange LN-3922's are the steel cup version of the AL ones Rive sells , and are great !

a reply to Mike on the SKF BB.  This is a symmetric BB, and they offer spacers up to 4mm.  I would go for the 116 and make sure you have the 3 available spacers (1.5, 2, 4).  This will get you up to the extra 10mm with the width plus spacer offset, and gives you 3 other options for dialing in chainline.  The SKF square tapers are Big, and the crank arms don't seat very deeply on them.

ps - might also call the folks at Boulder Bicycle since they sell and install both the SKF and Carmina.

Thanks for all of the input, but it turns out I've changed my fancy crank overhaul plans some. I decided to get White ENO arms and set these up as a double, and I'll be pairing it with a 113 mm SKF BB that I bought from Compass. Jan Heine said I should be fine with a 113 for that even though they run a little big, and this solution seems a lot simpler than messing with a TA setup. I had never heard of SKF BB's until a couple of days ago but man do they look like some next level engineering!

In case anybody is interested, bikebling.com is selling the ENO arms for $180 and you can add a 10% coupon to that for $162 shipped. I had upgrade with a deal like that! http://www.bikebling.com/White-Industries-ENO-Crank-Arms-p/whiteind-eno-crank-arms.htm

Where's the spider in that setup?

I assume you mean in the White Industries setup?  The big ring is the spider

When using White Industries crank arms, the big ring attaches to the splined part of the right crank arm and is held in place with a lock ring.  The small ring bolts to the big ring.  Check out lots of pictures at www.whiteind.com

Do you have one of the cranks, Bill? If so, I'd like to know how much mileage you've gotten out of your W.I rings. I read a post on here where Jan Heine said the rings he sells that are made of 7075 aluminum last ~25,000 miles and I was interested to know if White's have a high life expectancy as well. The proprietary rings issue irked me at first with this crank, but my hope is that the high quality typical of W.I products will make it worth it. 

[Bill Lindsay]

I do have a White VBC crankset.  I've only had it a short while and I load balance across several bikes, so it hasn't seen a lot of miles yet.  VBC rings are 7075 aluminum also.    I'm not terribly worried about the proprietary rings.  If I get nervous I'll buy a few spares.

Yes, roller bearings on the drive side, and oversize ball bearings on on the left.  Putting a cyclotouriste triple on my old Raleigh, I had to go with 126mm.  With the crazy 73mm-wide BB boss on Raleigh, SKF does not recommend use of spacers, so it's fully symmetric.  Looks funny enough to draw comments, but chainline is perfect and half-steps + escape adds huge versatility to a wide-6 in the rear.
