There was two pink/purple colored bikes. The one with the yellow head tube and seat tube was a Centurion. There was also an all purple colored Bruce Gordon. Both riders are from the Plano area and ride with the PBA.
Kevin, the blue bike I believe is a Nishiki. Someone posted a picture of what appears to be the same frame with decals over in the C&V thread. I didn't get a chance to talk to the owner much so don't know much else. I was busy up front making sure we didn't get lost and didn't get a chance to chat much with many of the riders. Next time I'm going to nominate a co-ride leader so I can trade off the duties up front so I can talk more with my fellow riders.
