Q: I just want to clarify that this headset bottom fits a head tube intended for a 1.5" steerer tube, with a 56mm I.D., but fits a 1-1/8" steerer... hence the "conversion". Thanks
A: That is correct; this lower headset assembly allows the use of a 1 1/8" steerer with a 56MM lower headtube I.D
Q: one other question... if the answer to my first question was yes, it does fit a 56mm ID head tube bottom and a 1-1/8" steerer, do i also need the conversion crown race to make it work? thanks
A: The conversion crown race is required and included.
Q: can i fit this on my kona entourage 2012??
A: That depends on what fork you are using. If you have a fork with a straight 1 1/8" steerer tube, then this lower headset will work fine (choose 49mm in the drop-down). If however you wish to use a tapered fork, you would need an external cup lower, which is item 205 CACTC1 (choose 49mm, 1.5 in the drop-down menus).
