Fixed Gear Bikes

It's almost certainly a 'wrong chain' issue.

The chainring and cog have to be of the same size and then you need the right chain that fits on them.

The main to sizes are 3/32 and 1/8, the larger being 1/8 and that's the standard size for BMX.

On the website it says 3/32, so I guess mine is 1/8. So I need a new chain AND chainring?

sounds like the chain is a 3/16 instead of 1/8. get a 1/8" chain

If your back cog is 1/8 and your chain and chain ring are 3/32 then get a new cog.

Although you could just run the 1/8 chain on a 3/32 setup. I will be a bit louder but not really a big issue.

edit:

it says in the link you posted that the langster comes stock with
Rear Cogs - 1-speed, 16 teeth
Chain - KMC Z510HX, 1/2 x 3/32"

So I would guess that unless he has made changes to the stock setup that the back cog is 3/32.

If it makes any difference to you Sheldon Brown recommends running fixed with a 3/32 drivetrain. If the setup is already good to go for 3/32 you might just leave it and get a good 3/32 chain which are easy to find and cheap. For the record I run 1/8 as do most tarck people.

this is what i ride

This is my freewheel

This is the chain around the fixed wheel(i flipped the bike over)

wrong size, yeah?

So i need a 3/32" chain and a chainring to match?

Nice tom. LOL at the 700 dollar wheelset in the background.

Re the post three above, just grab a cheap 1/8 chain like the kmc z and you will be good to go, it will be the cheapest route as you already have the cog on the wheel.

Jon, you're such a hater

i'd love a set of wheels like that. I've always though disc wheels and 5 spokes looked so much cooler than anything else. I wish i had that kind of disposable income!

Don't hate, appreciate :p

Actually aerospokes are pretty bad wheels. They are super heavy and not really that aero. For street riding the use of aero wheels is likely not even noticeable. The weight difference will not offset their aero properties. Further those wheels cannot be trued. Real track aero wheels are sick but in the world of bike wheels $700 doesn't go every far for a true aerodynamic wheelset.

Found this interesting: http://www.sheldonbrown.com/rinard/aero ... namics.htm

Here is a chart of wheels. Sadly aerospokes are not listed. Lower on the chart is better. Keep in mind that the main advantage of aero wheels is holding high speeds which doesn't happen in most city riding as most riders don't often maintain high speeds long enough to notice the affect. The time differences of aerowheels are only seconds over an hour long ride anyways. Also keep in mind that disc type wheels and really deep rims can be a pain for non track riding or time trials as they will catch in cross winds. That is why you almost never see two disc wheels on a bike. It would be hard to steer a front disc wheel in any sort of wind.

Anywho...

here is the new 29er mtb bike

Soon to be fixed.

Ya I put some ourys on there :p The bike is friggen sweet. Rolls over things like a champ. Climbs well and is just overall a blast to ride.

Here is a comparison pic to show the size of the wheels.

Man, slick rides!!

Those look really fun.

So I'm back in Finland, but before I left Berlin I ordered a new frame, Gorilla Hattara, through the Keirin Berlin store, which was a nice store for all things fixed! Btw, hattara is finnish and means candy cone, the frame is named after a finnish messenger. So I migrated all my parts from the first frame to the new one and got some new (used) miche cranks and a sugino zen chainring while doing it. This new one is more track geometry, which I like better than the road I had before. Also changed to 44x17 gearing. Been riding it for a few weeks around JyvÃ¤skylÃ¤ and I'm loving it! New backwards circle record, 4! Anyway, here's some pics!

you guys are stupid - that doesn't look anything like a track bike

Ville I just realized your frame is very very similar to mine. I don't know how I didn't see it before. Same fork as the EAI bareknuckle. Looks to be the same dropouts and the same rear brake mount. Can I get more info on your frame and ask what it cost?

edit:

Wow these frames are similar. Your frame has a 1" thread fork but mine is a 1 1/8" threadless. The clearances on the bareknuckle appear to be a bit tighter and don't allow for the larger tires that yours does. The seat post collars are a bit different as well. The bareknuckle might be a bit more similar to the Zengang model with the oversized tubbing. I wouldn't be surprised to discover if these two frames were made by the same hand in the same shop considering it already says they are made in the same country. I will look into it more and update later.
