Hi All-

I just installed a new set of Grand Bois Cerf Green Labels onto my Hed Jet 4 rims. They measure a bit larger than 29c wide on these wheels (23.4-millimeter rim). They even puff up a bit more in the next few days. They ride really well and are fast. I rode them on the double century circuit here in California last year and loved the added comfort and the secret added speed. I find these to be faster for me than just about any other tire I've tried, including the Challenge Parigi-Roubaix.

Here's the link:

I've had amazing luck with my Cerfs.  More than a year now on mixed city-street and paths with no flats.  Previously comfort meant giving up reliability to me.  These tires have upended the paradigm altogether.

 

The only issue I am having is the bike with the Cerfs clearly has room for Cypres.  When it is time to replace this set, do I stick with tried and true or move up a couple of mms?
