Help changing fork on Rush Hour

I have an 07 Rush hour and need to get a new fork to replace the factory one. I was considering the FK3507 Dimension 27'' Road Fork from Bikeisland or a Surly steamroller fork.

I was just wondering about the size. I don't know what size I need, 1" or 1-1/8"? The 07 catalog says it's a Raleigh chromolly track fork and that the Headset is "Ahead 1-1/8". So does that mean I need a 1-1/8" fork?

Also, the old fork is straight and I am unclear what effects switching to a fork with a rake would have.

Any other fork suggestions would be appreciated also. I chose those two because the first one is cheap and the second is reputable.

Oh and one last thing. Is changing the fork something I can do myself or would it be best handled by a shop?

You need a 1-1/8" threadless fork. A 27" fork is made for 27" wheels. Your bike has 700c wheels.

Judging by your questions, you know very little about bikes. I'd recommend you take your bike to a shop, have them show you your options for forks, get one through them and have them install it. You're probably looking at about $150 for parts and labor. You will not only be sure that the part you are ordering is the correct part and that it is installed correctly, but you will also start a good relationship with the shop.

While you are there, have them recommend a good repair manual (I like Zinn and the art of Road Bike Maintenance by Leonard Zinn). Read it cover to cover in your spare time and you won't have to ask anymore embarrassing questions like if a 27" threaded fork will work on your Rush Hour.

Once you read the manual, you will find that replacing a fork on a threadless system is pretty simple and can mostly be done with common tools. The exceptions being removing the bearing race from the old fork, setting the race on the new fork and maybe cutting the steer tube to length. You could do these yourself without the proper tools, but there is a really good chance that you'll ruin either the fork or the headset (or both) in the process.

the only reason i'd upgrade the fork is if i want to go carbon.

as mentioned, you need a fork with 1 1/8th steerer.

you'll want a fork with same length/rake as your original if you do not want your handling to be affected.

changing a fork isn't difficult but may require some specific tools you might not have, thus, you will probably want to take it to a shop to do.

I'm not sure how the poster's gender has anything to do the thread topic or the type of replies that should appear. Tim's post was very helpful and not particularly lacking in tact (maybe a bit gruff). But whatever.

You should check out Sheldon Brown's website. It's always a good place to get some basic advice and technical explanation. Also, you should do a search on bike forums for "fork rake." A lot of people find it confusing, so there are a bunch of threads that will be useful.

NEVER CHANGE YOUR FIXED GEAR FORK ON YOUR OWN!!!!!!!!!

I work at a bike shop and have seen way to many people come in who have done this and seriously wrecked their bikes. Once the fork is removed, the star not will crack and pretty much implode, resulting in your steerer tube breaking and your fork tubing to become extremely brittle in any conditions. Also the headtube will be permanently damaged, and the frsame will be trash.

I suggest brining the bike and parts into lbs, and have them do sizing and changing (about $70-$80 fee) so you will not ruin your beautiful custom midtown fixie.

btw, i am very legit and experiance. I have sex with women

Dude, that wasn't funny or helpful or even sarcastically helpful in that way where you say everything the opposite of what would really be helpful. It was kind of halfass funny but with some real advice (going to LBS, getting fitted) thrown in. Posts like this could cause someone to think that good advice is somehow part of the joke. You really need to work on your technique.

Thanks everyone. Tim seemed a bit insulting but I guess I don't know anything about bikes. I was just asking questions before I made mistakes. I don't know what happened to the last fork. When I referred to the original I was referring to the original catalog specifications and the fact that my girlfriend has the same bike (I know that's kind of lame but it was a cheap coincidence, not a lot of shops around here, but a few sell raleighs). I don't have a fork.

Thank you for the manual suggestion Tim, I will buy and read "Zinn and the art of Road Bike Maintenance by Leonard Zinn." As far as not having to ask "anymore embarrassing questions like if a 27 threaded fork will work on your Rush Hour," well, it was just a question from a newbie until you made it clear that I should be embarrassed. I didn't realize the 27" referred to wheel size. Off the top of my head I thought it may be the same, but should have looked closer.

I understand that the bike will handle differently with a rake, but i've never ridden it without one so I don't know how that will affect me.

I am new to all this and am just trying to get a start. As far as my "beautiful custom midtown fixie" as mentioned by Patricky, I don't know enough to even be insulted but I feel like I should. I live in a small town with few hills and I'm riding an inexpensive single speed with a freewheel that is available used locally. I'm not an inexperienced hipster, I'm an inexperienced person trying to get into bike riding because I enjoy is and feel like it's the right thing to do.

Anyway, thanks for the advice I've received. I've read a lot of the forum it's just hard to get what people are talking about with my limited experience.

oh also, I am a guy, which still seems like it doesn't matter, I just like the name "lot's wife" because that is what she was called in the stories. She was never named. They say she turned to stone, but they don't know, if they had looked back they'd of turned to stone too. She just chose a different path and they told people a cautionary tale.

You can ignore Patricky. That poster has been deemed insane.

So you got a rush hour frame without the fork? Once you figure out the rake issue, you can check out webpages like nashbar.com, bikeman.com, jensonusa.com, benscycle.net, and a bunch others.

Once you get it built up, post a pic!

Forks are available at lots of different places. Most have a bit of rake listed as rake or offset (even if the fork arms look straight), unless they are a special trick/barspin fork. The less rake/offset the tighter the front tire to your frame. It will turn a bit faster, but the tire will be closer to your toe clips and may over lap some as well.

The current model shows 45mm offset for 50 and 53cm frames and 40mm for 55, 57, and 59cm frames.

The Steamroller fork looks like it would work fine, or the new Leader fork looks similar to the stock one and comes in chrome for no extra cost...
http://www.leaderbikestore.com/pd-le...steel-fork.cfm

Soma has a couple that would work depending on the reach of your brakes...

Many Carbon options are out there too. A bit more expensive, are lighter, and ride smoother (some more shock/bump absorption) than steel.

yeah, some helpful advice was given but it was pretty snarky.

not everyone has been riding for years, so when those that are new to cycling (myself) have a question, it reflects poorly when people lace responses with condescending comments... i mean, do you actually want people to ride a bike or not? i try to read as much as possible and teach myself what i can from reading online and such, but alot of the knowledge really just comes in time and hands on experience. i have a TON to learn, but i pick up some new knowledge all the time and a positive environment (here and on the street/shop/whatever) makes for much more conducive learning.

i will have to get my hands on the zinn book, too.
