[MENTION=422271]eric044[/MENTION] It was a charity ride so lots of riders of all speed ranges. nothing would have changed climbing wise or crusing speed wise, but the downhills I got to 42mph just coasting with slower packs riders on there brakes and cars doing 45-60mph few inches to the left of me. I was often in the cars lane to pass riders that were taking up the bike lane. The FW was my extra layer of insurance for stupid **** not to happen. The 18t fixed is on the other side of the hub
