The bike situation that I saw in my recent trip to Spain may have stimulated me to consider this because all the bikes I saw in the pilgrim road were MTB which was a totally difference scene from that in French Pyrenee. The road surface was indeed a definite problem for narrow road racer tires. I would at least like to couple my existing frame with some cyclocross tires logically. Ultimately, my two bikes could possibly have different focuses in their concept in order to cope with wider applications.
Firstly, BH Cristal will gather most of light-weight parts to enhance its character as the running machine. I obtained this BH frame originally for my partner just in case she joins biking, but so far she stays reluctant, therefore it may be time to assume this bike purely for myself now. When it is coupled with ZIPP wheels in place for sleek, aluminum Mavic, the mood became completely aggressive. I am thinking of Di2 installation in the future, but this Cristal frame has no provisions for Di2 according to BH, and everything has to be external, which distracts my motivation quite a bit. If I get FC-9000 cranks instead and compromise with Planet-X CNC brakes, the weight can be very close to 6kg realistically. I have Prologo C.one30 saddle waiting for my pick-up in US for this project.
