What size is the front wheel?

24 inches per the Internet.

Also alluding to what Bah Humbug has been talking about, I have absolutely no idea what size I would need.

AG used to hammer out endless hours in the corn fields, so there are places you could probably drive to. Not sure where you are in relation though.

There's plenty of quiet, straight miles out here.

The issue is that I wouldn't want to ride anything less than 28mm tires, even on a steel frame.

Proper modern TT bikes weren't available yet, so that was what aero looked like. Carbon shaping allowed the headtube to get short so riders could get low enough without the smaller wheel. The smaller front wheel also helps in the TTT because it gets the rider's body physically closer to the rider in front, which aids the draft strength. It's bad for tri where you have flat supply issues.

Also, this was prior to everything being wind tunneled, so they had to build a frame and test it in the velodrome and see if it worked. We could do better now with steel if we wanted to, but it would still be slower than a P2.

I think the disc brake TT bikes can, at least some of them. That's getting towards big prices though.

Edit: Yep, the P3X and PseriesDisc can take 28mm measured with the UCI 4mm clearance.

It's more than that. When they start wasting resources to pursue trivia, there's usually more going on than meets the eye. Irony not intended.

Me neither.

I was late getting out the door (8:10-ish) this morning but really didnít expect the heat and damp so much so that I considered just closing the garage door and retreating back inside for a couple of seconds. :twitchy:

As well documented here, I am frequently admonished by [MENTION=25227]Velo Vol[/MENTION] to be more specific. I was talking about rider position not the equipment.

They look too upright and prone to catching wind. I was thinking lower with flat back.

Do you remove the descents from your rides? Down hill--no effort.

Being more resourceful than WhyFi, I proceed past the sign to see if the bridge is actually "out"--i.e, no longer there. It is not. I walk around the barriers, over the out/not out bridge, (at some cost to my average speed) and continue on my merry way

--my knee that I was worried about the past week wasn't too bad

--consumed no food, four cups of water pre-ride, two more post-ride

The End.

Downriver tri swims count.

I have no idea about cycling specifically, but obviously wind tunnels were widely used for other vehicles back then.

I pedal going downhill . . . sometimes.

Ah, yes. Even when I started riding cyclists were mostly terrible TTers. I watched riders in Le Tour sticking the tails of their long-tail TT helmets straight up every few seconds for the entire stage. They've gotten better, but it's basically a different sport.

I was referring to bikes and bike parts specifically.

Two hours on the single speed. Super hot.

Three bottles. Salt tablets. Glad I went, but I need a nap.

Why?

Probably because flat. The SS is a simple, elegant option for flat rides. It becomes a problem when hills appear.

They are making aero faces, though.

My recollection is that the smaller front wheel funny bikes were most useful for team pursuit on the track and team time trial on the road. The smaller front wheel allows the rider to draft a little bit closer, which can make a decent difference.

Nailed it. Specifically, brings the bodies closer together, and those are most of the drag.

I'd be really surprised if the 1988 cycling teams in above video had not done some kind of wind tunnel testing. It wasn't that long ago.

You guys are posting up a storm today. Must be the heat.
