Giant Single Speed Conversion
So I just got a new cannondale for my birthday and had my old race frame sitting around being useless. Its an 05 Giant TCR Alum frame. I decided I needed something for cruising around campus and town and stuff so I decided to convert it as cheaply as I could. Pretty much everything was donated or bought extremely cheap.
I started with chopping the bars and flipping them over. Then I took off all the unused components like front d, bottle cages, brifters. I purchased a single speed conversion kit for the rear, and took the big chain ring off. Put a little aero brake lever on and voila, a super cheap singlespeed. Im running a 36x12 setup, its a little weird but its all I had to work with. A few questions: Is there any other options for tensioning the chain? I hate having that huge deraillur on it. Any input, criticism or complements are welcome :) http://img520.imageshack.us/img520/2...bike003xu3.jpg http://img187.imageshack.us/img187/9...bike005nl2.jpg http://img187.imageshack.us/img187/7...bike006um6.jpg http://img187.imageshack.us/img187/7...bike011ee0.jpg |
for chain tension:
eno eccentric hub. chain tensioner. or a frame with horizontal drops or trackends. |
Who makes a pretty cheap small tensioner?
|
nashbar or performance for cheap.
size isn't really an issue, i havn't seen any too small. you're still gonna have something hanging down there, no amount of shrinking will solve that problem for you. |
this should be a really light bike - drop the derailleur,and see if you can work it without or with a "half-link"
|
A trick to making the tensioner look smaller is to have it push the chain up instead of pull it down.
As far as which one to get, just grab a cheapo performance one and roll with it. |
magic gear
Also, ghost rings, if you want to mess with them, but I would go for the magic gear. -Rob. |
If that's not fixed, you probably should throw on a rear brake- no reason not to. Otherwise, cool build, bet it's light. I'm using those same wheels on my single speed conversion.
|
Looks pretty sweet, it's not cheap but Surly makes a sweet derailleur style chain tensioner that would probably fix that up nicely...and I second the rear brake idea.
|
Thanks for all the replies, ill probably just settle for the tensioner. I heard that if i use the half link my chain will stretch out overtime anyways.
Any specific reason why i need the rear brake? |

I haven't bought any levers yet, but I'm a little concerned w/ getting them to fit since the bar-chop is along the "curve" of the bars - if that makes sense. |
Im not sure what kind of lever it is, a friend of mine gave it to me. Its just some generic brand. About the bars, i had to shave a little bit off it on the underside but just some brute force got it down in there. But any more curve and i wouldnt of been able to get them to fit.

Any specific reason why i need the rear brake? The real debate is whether you need a rear brake (or more accurately, whether you need a brake at all) on a fixed gear, but we're not going to get into that here. |
Thought id show an update
Here's what the bike looked like before any mods(except a custom paint job) http://img232.imageshack.us/img232/6260/img00102sw5.jpg I found the magic gear for my bike which happens to be 50x16 or 48x16 46x16 ect ect so if anyone has a TCR then iv done the work for them http://img236.imageshack.us/img236/6869/img00162vt9.jpg http://img504.imageshack.us/img504/3711/img00163wh8.jpg And i chopped the bars and got some Oury's http://img89.imageshack.us/img89/119/img00149ci0.jpg Next thing on the way is a surly fixxer so i can take the front brake off, and then my bike will be done I dont think this bike weighs over 10 pounds, its light as **** |
I was hoping to open this thread and see i really huge single speed...
|
hahahaha sorry to disappoint, maybe ill change the title

I live on the edge
(and not a bad looking bike!) |
on the edge of life? i dunno
thanks, anyone got any good suggestions on cheap durable pedals? |
I like seeing modern road bike single-speed conversions. Looks fast and light.
Might want to look into these on sale: http://tinyurl.com/2255og |
so you chopped the bars twice? i liked the bike better after the first chop, but it's still a nice looking set up.
