Racing with 40 lbs in the rear tire

I would guess that would slow you down. Bailed in the PP race today not too far from the end, rear tire felt mushy, looked down and it was very low to the point where I saw no point in continuing (this was lap 8 of 10 in Prospect this AM). I was actually fearful of the 35mph+ descent on a tire with <50lbs of air.

I would guess that semi flat would go a long way towards explaining why that race felt so hard for me today, although I think it was a fast pace, I'm pretty sure no breakaways succeeded. I would imagine it's harder going 30mph with 50lbs instead of 160 in the rear tire. I was even more fearful of trying to continue and losing all remaining pressure on my pricey Zipp rim at the wrong time. That would suck. Oh well.

Actually, I didn't understand the headline. I thought you heard about some idiot who did training races with a tandem rear wheel filled with lead or something.

Same here, I saw the headline and thought that the idea of filling someone's back tire with mercury before a race would be pretty comical, aside from the entire toxic bit.

Naw, with your weight on top of it, I'll bet it was up to 110psi. Did you measure when your fat a55 was off the bike?

Couldn't be bothered to watch the finish after you DNF'd? What must your sponsor think?

I am the sponsor and I think I suck. But I did take the early exit opportunity to drive the 70 miles back to Chester, pick up my wife and daughter, and chauffeur them all the way to Kennedy Airport for their flight to Italy tonight. I got the Almost Five Borough Tour of NY City today (no Staten Island). I would have normally watched the end of the race, but I had some serious running around to do today, all on $4/gallon gas. Sometimes it can't be avoided.

My Zipp has been re-treaded and is ready for further action. I'll try this again next Saturday and barring a fatal collision resulting in a 5AM road closure on the NY Thruway (last race) or a puncture (today's race) I'll be hammering with the 35+ kids again.

Dude, I pump up my tire to 120 lbs or 160 lbs. and so does everybody else in NY. You know what you can do with your psi mumbo jumbo.

That sounds like a good name for a shrimp appetizer. psi mumbo jumbo shrimp.

Hence my lame attempt at humor and an ill-placed winky smiley. I'll get it in the right place this time:

No corners in Prospect Park. A bit of a screaming 35mph+ mini descent however.

Nobody's answering me. Does it slow you down much to have 50lbs in your rear tire instead of 150? Wouldn't that absorb a few watts @ 30mph?

I mean, come on fellas, talk me down off the Velo Ledge here.
