BB Size? TOYO Atlantis

[AMAC]

Hey Everyone,

I have some new wheels coming in and will likely be able to setup my Atlantis very soon.  I wondered if anyone could offer some advice on BB sizing?  I imagine someone will have a similar setup.  The frame is a 58" (bought from the group a few months back) and I plan to switch over a Sugino XD-600 triple I have from another bike.  I believe the inner ring is 24t.  

Thanks in advance,

Andrew

Andrew,

My 2007 Toyo Atlantis currently has a 68x118 BB paired with a Sun XCD with 46/30 chainrings. Its a double crankset, but for what it's worth, that's what I'm running.

Andrew:

My 58 cm came with a 115 (maybe 116?) BB in 2003, and it worked fine.  When it finally conked out, I went 110 & there it was a close fit, but worked.  After that one died, I went with a 113 mm, which gives comfortable clearance with the chainstay.  The crankset has always been the Sugino triple that came with the bike (24 tooth inner ring). 

The Atlantis has had some subtle changes over the years, but Gabriel's experience with an '07 & my experience with an '03 show that various BB lengths work.  Do you know what year yours is?  Or what the serial number is?  The serial number on mine is AT 00519.

  The Toyo Atlantis with a stock 24/26/46 XD triple originally was suggested by Riv with a 107, but later they changed that to 110 or 113. Everyone's idea of "enough" clearance of the rings to frame varies, and no 2 frames are ever exactly alike.  It should be noted, the driveside axle length of a 107 is the same as the 110, but you can add some spacers under the lip and extend that side out up to about 2mm. Chainline was in the 45-46mm range. If you have a 113 however you could just use that too. I believe the spec'd chainline with a 113 is about 47,5mm, actual chainline will vary !  

   On my Bombadil, which has the same very bowed out stays from the BB, I used the XD with 24/36/48 rings and a 110 BB with 1.5mm spacers behind the DS lip. Clearance was fine. As I said, I coulda used a 113 which would offer a slightly wider chainline, but a 110 was what I had so I went with that.

Hey.  Thanks all!  Will likely give 113 a try next week.

Thanks again,

Andrew
