Perez Posted October 5, 2014 Report Share Posted October 5, 2014 Im getting my new bike built, just have a small question, how many washers people use on the drive side of the BB? 2 or 3? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
TOMTRIALS123 Posted October 5, 2014 Report Share Posted October 5, 2014 I believe if it is a 68mm shell, its 2 spacers like with my Deore Cranks. Correct me if I'm wrong though Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted October 5, 2014 Report Share Posted October 5, 2014 (edited) you cant put more than the 2 on the drive side or your bb will eat the 4 threads it's only sitting on,believe me 68bb:1 left 2 right 73bb:0 left,1 right e-type derailleur/chainguide:1 left 1 right now sitting here and waiting for dan to declare my experience in bike mechanics as "bullshit" again lol edit:http://www.shimano.com.au/publish/content/global_cycle/en/sg/index/tech_support/tech_tips.download.-Par50lparsys-0003-downloadFile.html/Hollowtech%20II%20Crank%20Installation.pdf Edited October 5, 2014 by FamilyBiker 1 Quote Link to comment Share on other sites More sharing options...

With me on it pedaling im sure it will hit it. i put another 3rd washer but with only 1mm, and it seemed to work fine, need to try it. Bit afraid of the threads of the bb..

dk2 Posted October 6, 2014 Report Share Posted October 6, 2014 no washers on the cups (maximum thread from the cups goes into the frame), and then add spacers on the crank arm spindel...This also supports the bearings in the cups better(at least on most common bb-cups).. 1 Quote Link to comment Share on other sites More sharing options...

Good point here, never thought of that. Thanks! Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted October 6, 2014 Report Share Posted October 6, 2014 I have to run 3 drive side to get it to clear (on a Skye but should be the same). I use a Saint BB (with Saint cranks) as that has 5mm extra threads so makes it less of an issue. You could just get a Saint BB. 1 Quote Link to comment Share on other sites More sharing options...

Matthew62 Posted October 6, 2014 Report Share Posted October 6, 2014 Would that BB require more frame threads if no spacers were used? I don't think so…..however it has been designed for DH bikes (with the intention of allowing more clearance with the use of chain guides), or for the example I gave. If you had a 68mm BB and used no spacers it could very possibly stick out…but then you shouldn't be doing that anyway. 1 Quote Link to comment Share on other sites More sharing options...
Perez Posted October 6, 2014 Author Report Share Posted October 6, 2014 I think with everything tight together its impossible to f**k the treads of the frame Quote Link to comment Share on other sites More sharing options...
