Last year, I was surprised that on the 24-hour races I was in, how many how full-on TT bikes there were, instead of a regular bike with clip-on aerobars. In December of 2014 I picked up a 2nd hand Cervelo P3C time trial / triathlon bike (for a song). Since many (most) of my training rides are solo, I figured “why not use a TT bike?” as it is faster. The exception is those routes that have a lot of steep climbing as the front chainring is 53/39, instead 50/33 like my other distance bikes. So this summer, but many of my 100K and some of 200K rides I have been using this machine.
Here is how to “Randoize” a TT bike (trick it out for use in randonneuring):
~ Add a second water bottle up underneath the aerobars with a hose that I can reach while writing. (This bike only has one water bottle attachment point.)
~ Add a custom-made eoGEAR bike bag that has Velcro long enough to go around the flat seatpost.
~ Long cage derailleur and a 12/30 cassette to make it easier getting up those nine or 10% hills.
~ Add a light extension bracket so the front main light is sitting below the handlebars. This position shows the texture and holes in the road better.
~ Mountain bike pedals to facilitate shoes that are easy to walk in.
~ Heavily padded TT saddle which presumably will absorb some of the vibrations of this stiff bike.
~ 38mm carbon wheels switch still except a standard 48 mm Presta valve. Deep enough to be slightly aero, but not so deep you get blown over in most cross winds.
