Thank you all so very much. So I ordered the Cannondale reducer from ebay. This will mean buying a 3rd fork. The bike is a 2011 Giant TCX medium size. This has become something of an odessey I refuse to give up on. I have lost 35 pounds riding this bike but am tired of the quasimodo riding position. I used a clamp style steerer extension and hated it; I bought FSA Gossamer cranks only to find out that winter salts seizes the pre-load bolt on the OEM cranks...so several hundred dollars latter and a fair amount of OCD has yielded the following: NOS TCX frame from Germany, large. Installed cranks, waited for 2.5mm spacer, now good. Ordered TCX carbon fork from "58cm" frame. This dude must have had this slammed cus this steerer is 240mm, like what I already had. Can't find another fork so I will buy a 1.125 steerer fork using the C'dale adapter, thank you. BTW, read that 1.5 forks would fit this frame so I have a 1.5/1.125 tapered headset waiting for a Vandessell carbon fork. 52mm integrated lower does NOT fit 47mm integrated head tube machining...ommfg! It, like me, is a work in progress. Found a bike I like and want to stick with it, canti's and all.
