Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Help! Single speed freewheel on Kilo TT Pro

Hey Everybody,

I was interested in purchasing a single speed bike, and after doing a bit of reading I ended up buying a Kilo TT Pro on BD.com (since they're on sale for $400, just $40 more than the regular TT). Anyways, I knew the bike had a flip-flop hub, allowing me the option of going either fixed or single speed, but I was expecting the bike to come with a singlspeed freewheel already installed....but it didn't. I didn't really have any idea what I was doing, so I just went on amazon and picked up one of these for $16:

http://www.amazon.com/Shimano-Tooth-...3288885&sr=8-1

I got it in the mail today, installed it, and it seems to work fine. However, the gearing just seems to be really high. The area I live in is very hilly, and I know just from taking the bike out for 2-3 minutes that the gearing is going to be too difficult. So what can I do to "reduce" the gearing? Is it because the freewheel I bought is designed for BMX bikes? Would it improve if I just bought something like a White Industries Eno freewheel instead? Do I need to increase the number of teeth (i.e. is an 18T easier than a 16T?)?

I apologize if the question has come up many times...I tried doing some searching but it's difficult to come up with effective search terms when everything in the forum is a fixie or single speed haha.

Thanks!
-Rob

The difference between your chainring and your cog determines how high your gearing is. Greater difference (bigger chainring or smaller cog) = Higher gearing. 18 will be easier than 16.

Get a freewheel with higher # of teeth. It will lower the gear inches, and make climbing hills much easier.

The other option is getting a smaller chainring, but that will be more expensive. Go to a bike shop and they will be able to answer your questions, plus you'll need them to take off the freewheel you already bought.

Awesome, thanks for the quick replies! So is an 18T usually the way to go for hilly environments or should I go even higher? 20t? I went with a 16T because I was in a local bike shop and overheard a conversation someone was having with one of the employees, in which the employee recommended a 16T over a 17T in my area since it's very hilly. Shows how much they know :-/

I'd enjoy watching you make it up some of the hills in San Fran with a 16T on my setup haha

The person they were talking to probably had a smaller chainring, thus a 16T freewheel might have been ideal. The kilo comes with a 48T chainring. To give you an idea, on my kilo I climb with an 18T fixed cog. I'm pretty skinny and not exceptionally strong. A 19T would make it even easier but my area isn't extremely hilly.

In Austin I use a 20t freewheel and an 18t fixed cog with a 48t chainring. I go fixed unless I am planning on hitting some good hills. There are always trade offs. That is why you went with the flip flop hub. The younger set is going to balk at my selection for the fixed gear, but I don't skid, so I don't care that it only has 3 skid points.

Alright, so I ended up ordering another cheap $16 amazon special, but they were out of stock on 20T's, so I went with a 22T. Got it in the mail today, put it on, and now my chain isn't long enough. I assume you can just add links to chains? According to the BD website, the stock chain on a kilo TT pro is a "gold edition KMC chain"...which I assume is this cheapie:

http://www.benscycle.net/index.php?m...4&currency=USD

So could I pick up another chain for $8, pull off some links and add it to my existing one?

Thanks.

Be ready for a HUGE difference. Though for the hills of SF that will probably be a good thing. Go to your LBS and ask them to add some extra links. (I think they do that). Or just buy a chain there and use the new chain and keep your old one for back up.

HOLY F##K. You are dropping 20 gear inches. You are going to flying up the hill now, then eventually into the sky.

To say this thread is a lil' old is quite the understatement!!

The freewheel in question is fine and all, but the selection of teeth is what was in question. What is the terrain like in your area? If it is relatively flat, or you have a good fitness level, a 16t freewheel could be ok. However, with a 48t front chainring, the 16t can be a bit hard to turn over with alot of hills or a low fitness level. You really need to tell us more before we can recommend something for you.

1/8 and 3/32 is the width of chain. Generally, road bikes use 3/32 and bmx bikes have 1/8. You need to know what your chainring and cog/freewheel is.

Since 1/8 is wider, it can be used for both types of chainring and cogs/freewheel. For example, I have 3/32 chainring and 1/8 cog, and I use 1/8 chain.

If you can test ride a road bike, several speeds will allow you to calculate it's gear inches, you may find that ideal gearing for now & today. But as you ride and become stronger and more conditioned fitness wise, you made need more GI. Two or three weeks of a more challenging route for your rides and you may find what fit your needs today is too weak ?

wow thanks for the reply guys. Im not worry about the # of teeth. I know the 16t will be harder to ride, but i figure thats a good work out either way. Im just worried about it fitting correctly on the bike. Also im concerned with the level of quality. like the shimano vs white industries. $20 vs $100?? i mean they must charge that price for a reason. Well i think Im just going to order the shimano since it states it can fit a 1/8 or 3/32. I hope its good....also it sucks that the OP got this for $16 and now its up to $20. lols thanks again for reading.
