Singlespeed & Fixed Gear - barspins?

kind of a noob question here, but im curious to know what fork/frame people are running that have the ability to rotate the bars 360 degrees. Ive got a giant bowery with specialized forks (43mm i believe) and im unable to spin the bars completely due to the tire hitting the frame. Im assuming I would need something like a 37-40mm rake to get it to work, but ive only just started looking into it. Since I would be needing a threadless 1 1/8" fork that will work with an integrated headest im guessing this wont be an easy task.

Any ideas?

thanks in advance

im running a single speed fixed track bike, I figured id post here. Asking the bmx guys doesnt make a lot of sense

single speed fixed trac bike, eh? Get a stem with a positive degree slops and riser bars and there you go.

ive got the stem and risers sorted out, its the tire hitting the frame that is making it unable to go around. Im figuring its my forks as theyre 43mm which is more for road bikes. Im just wondering what people are running (fork dimensions mainly) that are able to get a 360 rotation

650C front wheel. Has to be carbon fibre or it won't work.

wow interesting, thats the first ive heard of changing the size of the wheel, but it makes sense

i hate to love that bike.

are frames out there where a 700c front wheel dont hit the downtube?
i practice most tricks during work and working with a 650 front sukz.

straight fork or a fork rake that isn't massive like a peugot, you don't really need a smaller wheel.

get a road fork off an old road bike. some of those bikes from the 70s have forks with monstrous angles and miles of clearance.

trying to make it work with an integrated headset though, also has to be threadless 1 1/8" so its definitely limitting my options.

is that a mash bike ?

Usually when the bar spins, it's because I drank too much.

Why would you want to spin your bars? I guess could see it if you were a clown in a circus or something like that.

yeah, i want to join the circus

Are you running a 650 just so you can do bar spins?

You bought a 650c AND a new frame?! You are pretty damn serious about these barspins. Umm, I'll take your old frame and wheelset, haha - I am not looking to do any trikzz...

And on a Rush, a decidedly 700c frame, no less. Bad form.

Where'd you find a purple headset? Do they make them in 1 1/8?

IRO Angus with certain tire/pressure combos. (If you put the pressure to 120 on Rubinos, they rub, but will still go through, but the ****e Hypersonic tires that IROs come with pumped to 90 go through no problem.)

that's the reason it works

well, it obviously wasnt the only reason to get a new frame/fork. I could have thrown a 650c on my old bike and accomplished the same thing. This bike fits me better and i like the tighter geometry.

so what are the specifics of this tighter geometry?

If you read the thread you would know that I had a Giant Bowery before the Soma Rush. Road compact vs Track, but you were actually going somewhere else with that question.. sorry it didnt work out.

Oh god.

Oh god.

fantastic contribution

I was asking what the geometry on the soma was now. Do you even know or care or is geometry just something that should be tight or track cause it sounds good?

I do what I can.

I got an old cheap Fuji road frame that spins em good with a 700c front wheel

you're asking to be an *******. You're still tryin that same angle, its not working. If you were actually curious, you would go to somafab.com. What a troll

Yeah, I figured you didn't swap frames just for barspins, haha. Even if it were the only reason, it would just be an excuse that I haven't used to justify a purchase with yet. :D

But your bike does not have the geometry listed on somafab.com. I don't feel like doing the math now but since you care so much about getting "tighter geometry" I figured you could tell me what it was. I guess I was wrong and you are just another ******bag hipster that likes to talk about "tighter geometry" but really doesn't know **** about riding a bike other then the two or three boring tricks he does ad nauseum.

I guess it was too much to expect a ****up willing to put a new wheel on so that he could do barspins to think about what other implications that have. For that I am sorry.

...oh ****tt Dutret Getting Tolddddd

They don't make purple anymore, I think. I saw a used one on ebay once, but it came and went when I had no money for it.

I was just being reactionary I guess. Whenever colored headsets are usually brought up, the answer is usually CK. :(

good god.. okay. Reasons for upgrading to the rush from the bowery for me were simple. I got the bike even though it wasnt exactly right for me because it was cheap. I had issues with pedal strike on the giant. I never really got comfortable with it and by going with a track frame, I wouldnt have to worry about it unless I was really really leaning (higher bottom bracket). With the Rush my positioning and posture is better. The steeper head tube combined with the 650 front put me forward over the bike more. I have short legs so going with a 53 would be better for standover, but not for reach. So I went with the 55. Stand over was sort of an issue at this point, but the 650 also helped in that area. The steeper seat tube is another plus for getting better posture. In the bowery I felt like I was riding farther back and more upright. The fork was something that could have been adapted to either frame, but I went from a 44 to a 38 rake. My goal was to get the best of both worlds. I like to ride and I like to do tricks. There were a few options available, I went with the Rush.

quit being such a hater. Why are you in this thread anyways? Just to talk ****? Id find your threads and come argue with you about **** youre doing if I felt like wasting my life away.

650 wheel with a 700 fork (with appropriate stem angle and height). geometry hardly changes.
sorry if it's already been said but i really can't be bothered to read the inevitable *****ing that will ensue with this question

In other words you can't answer my simple question: what is the geometry of the soma? I was curious whether if you have pushed it outside the bounds of normal bikes or not. Next time instead writing a ridiculous rant to justify your choices just answer the ****ing question or say "I don't know".

It should change about half as much as the change with the fork would. I think when I calculated that it was 4-5 degrees or something. That is a huge difference. Half that is still pretty big... like between a slack roadbike an a moderately steep track one.

Why do you keep asking me that? In the time it takes to type that **** you could have just gone to somafab.com yourself. Do you expect me to type all those dimensions out in a nice pretty chart for you?

i'm pretty sure it's not that much. when i used to ride dh/fr bikes the rule of thumb was that an inch on or off the fork length equated to approximately a degree slacker or steeper at the ht.

we're talking a very small difference between a 650 and a 700 wheel on the same fork. i can't see that causing a 2-3° difference in angle. not even close

i've ridden my 74°/74° conventional track bike with a 650 front wheel and it certainly didn't suddenly turn into an unrideable monster.

it's just not a big deal

Can you not ****ing read

Or are you just so ****ing clueless that you can't grasp the concept that dropping the front of the bike an inch changes the geometry even after you have been told that that is the case.

now youre reaching. Yes it changes a little. Its steeper if anything. Im bored with you. Thanks for your contribution you ****ing tool. Trying be some sort of halfassed purist elitist... snooze
If youre so interested, you do the math

55cm rush:
966mm wheelbase
74.3° headtube

Drop height from 700c to 650c:
[622 - 571]/2 = 25.5mm

Therefore the headtube angle delta is approx 1.5°, making the new headtube angle about 75.8°
Of course, this can be affected by tire size etc..

wow. simply wow. somebody needs to stop wearing panties that bunch so easily.
