I finally have a single speed bike. It's a 38x13 with On-one Mary bars and some spare parts. The seat post and saddle will be used on my other frame for longer races/rides.
Speaking of longer rides I have 12 Hours of the Hill of Truth coming up. Due to work I'll probably sneak in by the skin of my teeth. Hopefully I'll be able to do more than 4 laps.
On to the fancy pants helmet. It's a Catlike Whipser Plus and man does it breath. You can tell by the size of the holes, but that's juts half the story, they actually let air out! Air comes in one end, flows over my head and out the other. It's great; much better than the Giro Atmos. It's not flawless though. The retention system on the back is not adjustable with one hand. Which means I'll have to take the helmet off when I need to take off my hat. It's worth the compromise though, I'll be hotter more than I'll be cold that's for sure.
