The cage (single bottle) I have has a tab at the top that retains the bottle and fits perfectly into the podium bottle indentation ( I actually dont have the bottle fully inserted in the pic), it retains it perfectly, I have gone over some very rough stuff it never even moves, if you look at the pic carefully you can see the tab in the indent. Also the conventional under-seat bag just below the bottle wraps the cage so it doesn't get force open in bumps from the angle. I have been using that setup for a while it works great, I am testing out the underseat camelback, I like using that better but do not have enough miles on it to be sure it is reliable, it rests only on inch from the tire. It rained all day today so I didn't get to take bike on shakedown run. Once I am happy with the camelback Ill probably get a smaller podium bottle.
I will be doing a lot of hammering practice, the roads are long, smooth and empty here. Perfect for this bike. I am not a racer so normally I just cruise along at a comfortable sustainable pace (24 mphish) and only hammer when I need to (or want to) pass peeps. It is really fun to whoosh by 3 man pacelines
Next item is to replace the 28mm GP 4000 with a Gatorskin, had 4 flats on the rear 4000, none on the Gatorskin I run up front, and grind the fork a bit to run a 28mm vs the 25 up front now.
I m interested in that someone mentioned moving the brifters so they are inline with the bars for aero rather than at an angle like mine are, do you think it is much of a difference? Next time I replace the bar tape I may try this.
Also is there any nice bar tape that is cork like in black?
