Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Top speed bragging thread

Today, a little over halfway into a 60 mile ride with lots of elevation gain on the way in, I smashed my old speed record of 38.1mph. Today, I was trying to beat that going down a big hill and then I saw a truck getting ready to pull out in front of me and I hit it like I've never hit it before: 42.42mph. That's on 48x17 gearing. Holy Jesus I'm amazing.

So you're actually bragging about how fast you went down a hill?

Assuming 700x25 tires, I'll say you were doing 191 rpm?

lol, i thought this was going to be about sprints.

i'm actually petrified of going downhill full speed, even on a freewheel.
last time i bombed a hill i looked at my computer, i saw 37mph and realized that nothing my spinning @ssed self (47x16) could do would stop my bike. i freaked out more, started skidding, freaked out because i was still going 25, got a cramp in my leg, put my foot to the ground and have never bombed a hill since.
i love sprints, but hate fast descents.

manayunk, umbria st. not the steepest descent in manayunk, but coming down the back end it can get pretty fast.

terrain:

street view (would be easier to descern without the stupid van being in the way):

I have been to Manayunk a few times, and I can vouch that 37mph is easily attainable on a few of the hills there.

Sp00ki, ever eat at Mad River Bar and Grill? If not, I def. recommend it. I ate their twice and the food/service/drink specials were all above par.

i have not. i've only eaten at two places in manayunk:
couch tomato and the mexican place around the corner from it.
i only go to manayunk to ride through it (and back) on long rides, so we usually wait to do most of our eating and drinking once we get back to the city.
my ex used to live there, but we did most of our eating out down town...

The fastest I've ever gotten my 46x17 up to without the aid of a hill is 26.6mph but I just switched to 46x16 yesterday and haven't tested what I can punch it up to now.

I feel you, man. I ran a brake in SF just because the hills freaked me out. I either have to start the descent at nearly 0mph and do a lot of little speed checks, or Ted Shred hard the whole way down, which actually works pretty well, depends on the hill, of course.

55 kmh on the flats with 81 gi and 76 gi at 140 and 150 rpm.

70 kmh on a descent with 76 gi @ 190 rpm (with a brake).

90 kmh on a descent with my road bike.

Descending on the fg at 70 kmh was f-ing scary and I dropped my chain just as I was coming to a stop at the bottom.

This is my 'verified top speed', too w/t same gearing...my riding partner had a computer. On a tour of Ireland a few years back I KNOW I hit speeds over fify, but w/no docmentation I can't count 'em.

Btw, I got yer back, bro.
