Got bored.

So I flipped my handlebars upside down.

Also, I measured the top tube length of my bike and it's about 22".

So I guess it's the bars that make my bike feel so short.

With a slanted top tube, the TT length should be measured from the intersection of the centerline of the top tube and the centerline of the head (steering) tube horizontally to the centerline of the seatpost...

see the green line here...

the other interesting measurement is the seattube length, which I show there as 19" as I'm measuring from the bottom bracket center to the intersection o said virtual top tube, same as if it was a traditional road frame. this is NOT how bike makers measure it, they go from the BB center to the seat bolt.

just an aside, I put down the seat and head tube angles wrong, I measured them from vertical, instead of from horizontal. so, instead of 16 degrees, it should be 74 degrees, and 18 should be 72.

that red frame was stickered as an 'extra small' 15"
I was nuts thinking 6' 220 lbs of me would fit with the right seat post and bars :loco

but, I made a 5'3" college girl very happy when I sold it to her after a bit more parts juggling.

Watch it! Next, you'll be stripping everything off it and heading to the velodrome. :lol3

Yeah, I can't say it was perfectly level, but I measured from the middle of the intersection of the steering head and top tube to the middle of the seat tube at the seat tube clamp.

And the pic is a little slanted so it was pretty close to being level.

Go to a bike shop and buy a pair of $10 straight mountain bike bars. It will feel a lot better.

I plan on doing that when I have $10 to spare.

Outstanding!!! Thanks for the Pics!

They might build a Velodrome in Rock Hill, SC. I'm desperately wanting them to do so.

EvilGenius 08-20-2010 08:25 PM

Riding alone on unlit paths at night is creepy, especially when animals scream at you.


It feels a lot easier to put power to the ground now. I am more hunched over, but it didn't bother me like I thought it would.

My hands did start cramping after a little while, but no numbness. I still think that can be cured with better grips or some padded gloves.







Edit: I was also afraid it'd be too close to hitting my knees, but once I got out and rode around I can easily turn a 10' circle or less without even coming close.

I scored this bike for free the other day! It is a size big for the girlfriend but it will work. The previous owner crashed the bike hard and did not want it anymore.

It does not have the stock wheels, it has a set of cheeper Alex wheels. I had to buy some tires for it, align the der hanger, buy a seat and seat post for it and installed some splitter brakes.

I love the Pilot bikes from Trek. they are almost cyclocross bikes, I was able to fit 700x37 conti contact tires on this bike.

Went to Marymoor Velodrome last night for a beer,

http://mr-head.smugmug.com/Cycling/B...7_pcVGW-XL.jpg

http://mr-head.smugmug.com/Cycling/B...6_im7d5-XL.jpg

Fun time.

A dollar to park five to get in and a Fat Tire while we enjoyed the racing.
Tough shooting though.

Nice pics Mr. H...

Out for 70 miles this AM in 4:30. A little beat over the last 10 miles, but I guess that is to be expected. Still building my miles. But I may move up my time line and take the Mtn Bike off road tomorrow. Depends on how my legs feel.

Gummee! 08-21-2010 12:58 PM

I miss racing track... :cry

Next season after I've managed to get into a shape other than round. :nod

Things are starting to feel/look better, but I'm nowhere near having the speed/power to race yet. :bluduh

So, all y'all take it from me: DO NOT STOP! :nod

edited to add: Marymoor's a big track! 400m is a LONG ASS way around! Sandy Eggo's 330m. The new Home Depot center's the UCI regulation 250m. Ditto with Encino. The 'drome here in Boulder is something insane like 140m. :eek1 Can YOU say 'blender?!'
