[MENTION=227213]wphamilton[/MENTION] I would say give it a few days then go for it. Who cares if another rider destroys it, personal pride lasts (so does a screen shot and redundant backups).
I was happy to get my KOM yesterday. I never thought I would get one since most of my routes are training rides by TTer's or done as small hill repeats. But the bridge I go over only has a few hundred in the list and I was number three with the two above me being in cars. I got the cars removed and got a KOM on a 35 pound tourer (no kids seat and one pannier). It felt good. I still feel good being in the top 25 percent at the worst in the TT interval segments.
Meanwhile I felt fast yesterday and I was tearing up the hill to check out an old Dave Scott. I passed a guy who later caught me after I got caught at a sequence of four lights in 1.5 km. When he caught me he asked if I had a motor on that thing. Smile, no but I usually have a kid on the back, so I 40 pounds lighter than normal. Always nice being complemented for speed on the commute.
Anyway checked out the bike. A bit too small, it was two block from home. So the final four blocks (cumulative) of my commute I had two near misses and one aggressive tailgater. I posted in the need for urban lighting about it. I had turned my lights off to look at the bike, rode one block to the store and three blocks back home. In that stretch I had a lady come at me head on, another tailgate and a guy run a stop sign. I did not have my lights on and attribute it to that.
The this morning I had a lot of people turn off side streets misjudge my speed and need to accelerate when they realized they cut me off and I was going fast.
It was a nice ride otherwise. Cool, quite. My son even commented on the quite roads. He said, "Dad, I cannot figure out why it is so quite right now."
