was planning to do that ride myself but due to family commitments no go - how were the climbs on cx -?. have to say those cx bikes fly along on the gravel roads, of course coming from an mtber they have their limits on rough single track, but alot of fun finding the smooth line. once YTs dry out there's some great cx routes around.
I did Gravel Ginders yesteday on my 29er 3x9, and survived just about all the climbs except Breckneck Rd out of Yarra Glen. There was definately a lot more pushing done by the CX riders that I saw, there was some very steep pinches that would be just about impossible on standard CX gearing. That said, there was more than enough easier climbs and road sections where the CX bike easily made up the difference.
Edit: I just looked on strava, Breakneck Rd is ~30% grandient at the top, no wonder it hurt!
