Title says it all. Want to order a new chain guide but don't have bike in front of me to measure which type it is.
Thanks Greg
I believe it's neither. Press fit BB with no provision for a chain guide.
I believe ISCG 05, as usual on giant's Unsecure image, only https images allowed: http://www.thebikelist.co.uk/images/models/Giant/2010/Reign-X2_10/Reign%20X%20Frame.jpg
Reign x2 is isg05 however the tabs are rotated so not all chain guides will fit correctly . Mine is a 2010 and came with a bb mount chain guide that uses the isg05 tabs to limit any rotation of the bb guide . This was fitted from new.
