THIS is slated for May 19. I am planning on riding the Merckx if I can fit at least a 28c tire front and rear. If not, it may be the RB-2 or the ProtoRoller. Tuesday training ride will determine gearing. If by some miracle I'm able to run the 32c Vittoria CX tires then I may opt for the 42 x17. If a skinnier tire is mandated by frame limits then the 45 x17 might remain. After 6+ hours in the fixed saddle, the lower gear might be appreciated by (viet)M'Knees
