Singlespeed & Fixed Gear - Trying to finish my first fixed
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
So I hate to post another "please help me build my bike" thread but I couldn't find the info I needed in a search. I have my frame and fork, wheels, bars, brake, and brake lever. So I need a bottom bracket, crankset, headset, stem, pedals, seat post, and saddle. That's a lot of stuff but I got money for christmas from my family so I could buy the rest of the parts. I have about $250. I could buy all this stuff at IRO for about $250. I don't think I've left any parts out but let me know if I'm missing something. I'm also not totally sure what gear to go with, my cog I have on the wheel right now has 16 teeth. Also I'm not sure about BB length, or what length crank to get.
I plan on getting it put together at a LBS and I'll also buy some of the parts from them since I don't know how much chain I'll need and things like that. As for the frame the parts are going on it's an '05 langster 52cm, I'm also about 5'9" if any of that matters. TIA for any answers I hope I didn't leave anything out.

that frame sounds a little small for 5'9"...
For your 16 tooth cog I would hazard a recommendation of a 42 or 44 chainring.
Crank length should be either 165mm or 170mm. The bb length depends on which cranks you get. For exmple sugino rd cranks match with a 103mm bb. Sugino 75 takes 109mm bb.
Perhaps you could get a cheapo stem to figure out what length you are comfortable with.
IRO stuff is pretty good, getting everything from IRO would make things easy.
Well I have a long torso with short stubby legs, but I got on a 52 at 2 different shops and they both said 52. I guess I'll find out for sure when I start riding. I know a lot more than I did a month ago but I still need to learn a lot more.

In that case, it will probably fit just fine. You might need a rather long stem.
I would also think you'll need a pretty long stem. 13cm is probably a good place to start. If your frame is threadless, finding cheap, long stems is easy. If your bike it threaded, it will be a little harder. I also agree that IRO sells decent stuff and is a good place to get everything. You could probably save a bit of money if you're willing to wait for deals, but since you sound like you want to get it together ASAP, IRO is a good way to go.
Yeah I'd IRO it if I were you. Get on the bike ASAP; if any of the parts you get wind up sub-par you'll learn about it a lot quicker than browsing through forums. Not to mention that youll be having a lot more fun.
iro for the win tony is a great guy
oh don't feel bad about being built like elmer fudd I am 6' 4" and have a 32 inch inseam I ride a 56 and a 54 and bothe feel nice
keep those stubby legs spinning and drop anyone who says different
Thanks for all the help. The frame does take a threadless headset so at least I know I won't have trouble with stems. I'll probably order the stuff some time this week. How long would it take for ground shipping to fort worth, TX. I used to work an internet business packing orders and I know it can take awhile to process orders after they've been ordered. Only reason I care is I'd like to have my parts by next saturday so I can get it together on sunday and monday, my days off. Yeah I'm getting pretty sick of looking at a frame with wheels and nothing else. Also is the cheap saddle on IRO pretty good or should I just get something else? This is just a commuter recreation bike so a comfortable saddle would be nice.
Retem, at least we can pack on more weight and not show it as much. To bad buying pants will never be easy.
Finally looked to see exactly how much money I can spend on the bike in the next 2 weeks and I have more than enough, so if I don't get a response from the guy I bought the bike from on if he wants to sell me the parts I'm just going to order them tomorrow afternoon.
I've read on this forum that LBS don't always like to put together bikes with parts from the internet. I plan on getting the wheels trued, buying the chain and brake cable from them, getting the bars re taped, and probably buy some accessories through them. I know they need to make money to but I've already explained to them that I'm on a budget and they told me to look for a used frame or do a conversion so I don't think it will be a problem but I also don't want to come off as a jerk or anything.
Hey kbrown, you might want to consider getting one of IRO's Brooks B17s instead of the IRO plastic saddle. It's hard to find a better price than what Tony offers, and the B17 rules---I love mine.
Well I've seen people suggest it before I'll probably go with that since I have a little bit more money to spend. I went to go talk to the guys at the shop about an hour ago. To bad I forgot it was New Years and they were closed. I'm going to take a better look at the brooks but I'll probably get it.
EDIT: I just looked on the specialized website and it said that the stock spindle length was 103 mm. All IRO sells is 110mm bottom brackets and cranksets. I read a thread earlier where it said the length of the spindle would effect the chainline being straight. The wheels are stock also so I'd like to know what I should use if it really matters.
EDIT: re-read that thread and sounds like spacers will solve this problem.
I wanted to bring this to the top one more time in case anyone can add something before I order parts tommorow. Any kind of advice would be appreciated I haven't biked in about 3 years except for once when my car broke down and I borrowed a cheap dept. bike to get around. I enjoyed it even though it was cold so I've just been waiting until I could figure out what route I wanted to go. I'm excited next time this week it should be getting assembled if I'm lucky.
I wouldn't commit to chainring spacers or respacing the rear hub if you can get your chainline right by dialing in bb spindle length. What specialized cranks are you using? Are your rear hub and cog both IRO?
I don't have a bottom bracket or cranks. All I have is an 05 langster frame, fork, and what I'm almost 100% sure are the wheels that came with the bike stock. Since specialized archived all their bikes I just looked and it said that the original bottom bracket had a 103mm spindle. Where can I get a good 103 mm bottom bracket and crank?

ebay could be an option too, if you know specifically what type of crank model you want.
LBS could probably supply you with a BB for reasonable price.
go with the cranks and what not from iro the chainline should line up to 42mm the langster is an ss track frame and I call it that loosely but it is
the iro cranks are cool
also if you get a b-17 stuff a plactic grocery bag between you seat rails then you will have it to protect your saddle from watter when they get wet they get soft and ride like garbage and then when they dry out they harden up sooo bad
Yeah the iro cranks and bb should work fan ****in tastic, as long as they are for the same kind of shell that your langster has. (Edit: Google says they are! Both are 68mm, english threaded.)
I think you are confused: bb spindle length is totally independent of the shell width. Picture a tp roll with a pencil jammed all the way through lengthwise and poking out both ends; this is the shape of your basic bb. The bike's cranks attach to either end of the "pencil". Dimension-wise, the shell width is the height of the roll, and the spindle width is how long the pencil is. For a given shell width you can run all kinds of different spindle lengths to adjust chainline.
Don't worry about what specialized said about bb spindle length, that 103 figure is meant to go with whatever cranks came stock on your langster.
+1 on the grocery bag, shower cap, helmet cover or whatever; when a brooks gets soaked it also discolors and looks ass, if you care about things like that. Don't get the official brooks saddle cover, it's useless in the rain. PS: in spite of these kinds of hardships I still have brookses on both of my bikes and will probably have one on the upcoming third bike.
Finally, if there is a bike co op in your city you might find that a friendlier and more hands on/ educational place to get your bike built up than the lbs.
Thanks for all the help. I don't think we have a co-op here though but this shop seems like a cool place http://www.trinitybicycles.com/. They were a lot more helpful than the other shop and they have workshops every month and weekly bike polo. Thanks for the help. Now I wait.
