Wanted: 15t 1/8 Cog so I can beat a moped & Mavic Pursuit Bars

I Need a 15t 1/8 Cog, so I can beat a boy that goes to my school, he has a moped and I wanna beat him in a race with my legs...
With a lock ring preferably.
And a pair of Mavic Pursuit bars.

Nothing overpriced...I'm a poor school boy after all.

steroids ftw

lol, i used the rabbit program to work it out, at can spin at about 150rpm maximum, and im running 41-18 at the moment, so with a 15t ill be able to go 32.1 mph, and he's only aloud to go 30, so i'll fuck him up.
(the reason for 41-18 is i live in hastings where the hills are steep as fuck, good for training though)

It also means you can cycle away from Hastings a lot more quickly.

YES! ill be in london in no time! And if i get the mavics, it'll make me more aerodynamic and reduce the drag so i can get away even faster.

Mavics are fairly rare, try Profile Airwings.

You have taken into account wind resistance, friction and drag? If you manage to hold that 32.1mph for longer than about 5 seconds on the flat, then let us know, David Brailsford might be in touch.

This thread is fantastic

To humor you, I'd be willing to part with my 12t, for a few hours, if I can watch the race.

I think you should be improving your cadence in that case, atomcf. get up to 200rpm and you won't need as high a gear.

Also, it's not as easy to push a bigger gear to higher cadences as you might think. I would wager that it would take you longer to get to your top speed than the race is, by which point your mate on the moped will have either won, or crashed and killed both of you.

@rpm i've managed 43.6km/h on 41-18, thats about 150rpm, and also, if i can get the wind in my favour, which as its just about always wind, should be easy, if i train a bit first.

@citygent yeah, then he'll feel really dumb, cos we'll both beat him :). if it happens, ill let you know.

@asm i think i could push bigger gears, cos i train by finding big hills and going up them, so i don't think the power will be much of an issue, however, when im spinning at 150rpm, im wobbling quite a bit, so i dont see myself spinning any faster, or is that maybe because my seat is too high?

Why don't you just have a fight?

because hes bigger... no... wider than me, and i want to make him look stupid, on his motorbike with a moped engine. i want to laugh in his face, and tell him he should have spent his 2 and half grand on a bicycle.

Mavics are fairly rare, try Profile Airwings.

i've got airwings already, but they dont have enough drop, thats why i want mavics...

get airwings with more drop? hit them with a hammer? The more you ride at higher cadences the better you will get.

because hes bigger... no... wider than me,

Size does not make one strong...

Actions, it is, that make strength, and actions are made by the mind.

Your mind is in need of much training, young atomcf....

Don't listen to these jaded old bastards. You'll be able to spin faster in a race anyway, and even my fucking cat* could spin a 41/15 @ 150rpm for more than 5 seconds.

Don't worry about lower bars. If you drop your saddle a bit, you'll be able to spin faster, and your hamstrings won't be so stretched, so you should be able to bend your elbows a bit more to get lower at the front.

Is your adversary not allowed to break the speed limit, or is there some kind of mechanical limiter on his engine? He sounds like a fucking dick anyway, so you owe it to us to win this race. Win it right in his fucking face.

*even though he died in February

Good on ya fella! It's a tough challenge, but nice to see you setting your sights high.

I have a 15t cog and lockring you can have. PM your address I'll stick it in the post.

But you have to keep this thread up to date with your progress.

REALLY PISTOLERO!?!?
thanks

@BringMeMyFix yeah, he's limited to 30mph, because hes only 16, like me. I'll drop my saddle if it means i can go faster, but I really like it high... I WILL BEAT HIM.

I want to see a training video/montage please.

oyes! 80's montage ftw

i've got airwings already, but they dont have enough drop, thats why i want mavics...

If you're using Airwings at the moment, the easiest way to drop more at the front is to get some dropped handlebars (hence the name!)

What distance are you planning to race over? Not that it makes any difference, as you're going to get your ass handed to you anyway. Modern "restricted" 50cc bikes are set to 50km/h (31.1mph) because we went metric when they came under EU regulation. The Junior World Record for 500m standing start is around 50km/h, so in theory if you're world class you have a chance.

if you didn't get the 15t already you're more than welcome to borrow my TT for a one off - 56 /11 (on the flat it moves, good luck on hills tho)

i'm a failure. i realised that the reason i got to 150 rpm was because the road i was on was actually a slight descent. i feel like a readers wife, and that makes me very sad. I found a really flat bit of road, where i got to 130rpm, but even that i couldn't hold long.

The more you ride at higher cadences the better you will get.

so, does it have to be on the flat or can i find a big hill and just keep going up and down, up will improve my power, and down will improve my cadence. yes? or have i got it all wrong.

forgive me, for my misjudgement.

The change from 59" to 72"* is quite a big one. Better work on those leg muscles...
