24. How to Replace A Freewheel
Demonstrates how to remove and install a traditional thread-on freewheel cluster.
In this tutorial we’ll learn how to remove and install a freewheel on your bike. You may remember a while back when we covered cassette removal and installation. For this job you'll need a notched freewheel remover and a large wrench or vise clamp.
Here's how the two systems differ: a cassette is a series of gears that slides onto a freewheel unit. This is a better system because it allows you to replace worn sprockets without having to replace the freewheeling component (freehub body). A freewheel on the other hand, contains both the sprockets and freehub in a single unit that threads onto the outer flange of your hub. We'll be covering removal and installation of this style today.
First you'll have to remove the rear wheel from your bike. Then in some rare cases the axle nuts will be too big to allow the freewheel tool to slide into the freewheel, so you’ll have to overhaul the hub to remove them first. Now slide the freewheel remover into the freewheel and loosen it with your large wrench by holding the wheel on the firmly on the ground and turning your wrench counter clockwise.
If your freewheel is really tight, you may need to mount the tool in a vise clamp so that you can use the wheel as leverage. I don't have a clamp to demonstrate this, but once mounted in the vise, you can easily turn the wheel counter-clockwise to loosen the freewheel.
Before installing the new freewheel, inspect the threads on the hub to make sure they aren't damaged. Be careful threading the new freewheel on, as you don't want to cross-thread it. If it feels unusually tight right away, back the freewheel off and try again until it threads on smoothly.
To tighten a freewheel, all you have to do is get it finger tight and then re-install your wheel and go for a ride. The freewheel will tighten itself while you're pedaling!
hey just thought id share with you since you are all repairing these parts, i came across some grease last weeknd being sold at a small bike festival in manchetser and theres a range of different greases for the bikes. i spoke to them about it they said its a new range but it expected big things due to the standard of the grease so like you do i purchased some, i then took all my bearings out cleaned them all also my chain and sprokets too and apllied this grease and i get no random smell i use to get off my previous grease and it has a very good temp range! its brand new but would recomend it...

Hi, this is my first post to the forum! I have an old Focus MTB, bought it just recently second hand and I am also new to biking so please excuse me for being naive.
The problem started after the first miles with the bicycle, hearing a noise from the back. It was getting louder and louder very quickly and now, when I am pedaling everything is normal but when I stop and keep the pedals still, while on the road, the chain turns really loose and even goes out of the ring. This happens all the time. Tried with some lube and also tried to see if there is an obvious problem with the chain b... Read more >>
Removing SOLEUS freewheel DIY without a remover, garage style tip for everyone...
I was trying to clean and grease my wheel bearings, looks like removing the free wheel is a must do type of thing on my bike. I found that a regular old school Chevy GM craiger style lug nut fit in there perfectly. I think its ... Read more >>
I have. 2015 Defy 5. It has a FSA Tempo, 34/50 crankset.
Is this compatible with the Shimano 5800 group set? I currently have this setup with my Defy 5. She shifts a little rough on the front dérailleur. I guess what I am wondering is if I need to upgrade the crankset to the 5800? The bike came with a Claris setup. What I do not know is if there is an issue with 'spacing'. My current setup has 5800 shifters, FD, RD, chain and cassette (16 tooth removed and no indexing issues).... Read more >>
I'm new to bike repair. I use an old bike to ride around my neighborhood with my kids so I'm not a serious rider. My bike has a Shimano FH-RM40 7-speed hub and cassette. It's been difficult finding direct replacements for those components. Is there anything else that will fit without having to change out the entire wheel? I don't mind upgrading if the cost isn't too high. What are my options?
Thanks...... Read more >>
I need some advice. I bought a used, "as-is", 2015 Fuji Nevada 1.9 Mountain Bike with 3 x 7 gears from a LBS. I ride it a lot, 10-20 miles 3-7 times a week. The spin-on freewheel was a factory issued SunRun 14-34 and it literally fell apart in 2 months. (Yes, SunRun, not Sunrace) I purchased and replaced the old SunRun with a new SunRun 14-34 and after 3 weeks it is wobbling. I had another LBS check it out, they are scratching their heads. I am wanting a better quality freewheel than the Fuji factory issue of the P.O.S. SunRun Brand. The Shimano Tourney 14-34 makes sense but is there a better ... Read more >>
The chain on my exercise bike became too long over time and started "slipping". So I took the chain off and took off one section (2 links - a female and male) and replaced the pin to complete the repair. Now the chain is too short to put back on the bike - what I needed was a way to make it one link shorter (not one section=2 links). Is there now a way to make the chain just one link longer? Some sort of male to female single extension link? Thanks.... Read more >>
Complete carbon fiber (frame) road bike less than one year old - 105 10 speed. Built it myself and it has been fantastic up to now. About a month ago I started getting a loud rattling noise everytime a rode over slightly rough ground (chip and seal). on smooth road it is silent. It is obviously coming from the rear part of the drive. I always ride on the big ring on the 4th cog from the top - flatland. Here's what I have checked : Chain is a good length but I have tried two links shorter and two links longer. Tried a brand new chain. checked that all bolts are tight, pulleys, ... Read more >>

The chain comes off my rear small sprocket on back peddling. The bike rides good other wise.
I have noticed other riders on the side of the road with the same problem. Without a wheel wrench it is quite hard to free up and put back onto the gear cluster. What causes this malfunction?... Read more >>
Being new to this hobby I ran across the 12" rule for chain wear. You pull the chain tight, right on the bike, measure 12 links, the distance between 25 pins, and if it measures 12" the chain is like new. If it measures 12 1/8" you throw the chain away and replace it.
Something new to check out now. i imagine a worn chain causes shifting problems as well as drive train inefficiency. Do others here you use this method for determining chain wear??... Read more >>
I am asking this one for my dad (78.5 yrs old). He just got a bike on craigslist (Marin Redwood), comfort style.
He likes it, but wishes that it had lower crank gearing. According to the Marin website, I see that it has a "Crankset: Suntour XCT light 48/38/28".
My dad says that he thinks the chainrings are riveted on, but his eyesight isn't the greatest, and I have not had a chance to go there and look for myself.
Do you guys know whether the chainrings are replaceable on this "XCT light" crankset? I can't find any specific info to ... Read more >>

First of all I have been trying to research this bike and have come up empty.
What I do know, it has a belt vs chain and it looks a little dry.
I don't even know where to begin to find a replacement for it because I can't find it anywhere on the internet.
