16. How to Replace a Freehub Body
Demonstrates how to remove and install a cassette freehub body. Requires a hub overhaul.
If your cassette cluster is loose or gets stiff you may need to replace your freehub body. To do this you'll need a 10mm allen key, and you'll have to first remove your cassette, axle and bearings as demonstrated in previous tutorials.
Once your cassette and bearings are removed, slide the 10mm allen key into the center of the hub, and loosen it by turning counter-clockwise. If the freehub is very tight and difficult to loosen you can get more leverage by mounting the allen key in a vice clamp and sliding the wheel down onto it. Then you can loosen the freehub by turning the wheel counter-clockwise.
Once the freehub body is removed, clean the hub surface and bolt and grease all the way around the bolt's threads before re-installing.
Gently thread the new freehub body onto the hub splines and thread the bolt back into the hub. Using the allen key, torque the bolt to approximately 45Nm, or about 400 inch pounds.
I think the rearing bearings are 13mm ID and 30mm OD. Are these measurements correct? Please help.

I won a Specialized Daily in a contest. It is a pretty sweet bike. But it has an internal gearhub on the rear wheel. I have never had this type of gear setup before. I am afraid to mess with it to get the wheel off. How the heck do I remove this wheel to change my flat tube? Thank you in advance for any assistance.

I have a fairly cheepish bike, Appolo Evade Mountain Bike. (The reason for it having a freewheel was probably due to price not age).
Anyways. So, there is a tiny bit of freewheel wobble which I have come across on a lot of freewheel bikes so I never considered this a problem. Freewheels just tend to get a little bent right? Despite this, shifting is just fine and smooth and the whole drive system is just good overall. However
When I ride up a hill, and I mean steep hills, doesn't matter what front/freewheel gears I... Read more >>

I wanted to replace the rim on my roadbike and heard from a friend that I should do it spoke by spoke, that way I don't have to be careful where to put which spoke. I tried that and now the new rim has kinda an egg shape and I can't fit any more spokes (I got stuck after switching 18 of the 32).
(both rims are 622x15c)
1. Buy an already built new wheel and be done with it?
2. Start over again?
3. Remove all of the spokes from the old rim, learn how to align them correctly and try it again?
4. or something else?

I recently bought a second hand Giant Upland SE and to be frank, it is my first bike with multiple gears. The bike functioned normally for the first day or two. I could shift between all the gears. When the bike is stored indoors, the pedal and wheel work fine but once I take it out in the cold (anywhere from -10 to -30 degrees celsius), the pedals rotate freely and have no action on the wheel. Also I am not able use some gears on the rear wheel. Can anyone please help with an explanation and solution?... Read more >>

Recently bought a slightly used 26" meridian trike. While replacing wider tires on the rear, I noticed an issue with the rear drive side wheel hub. The wheel is held on with a nut and single washer. The hub is not held firmly in a location on the axle and is able to slide back and forth on the axle a good half inch even though the nut is tightened all the way down to its bottom threads on the axle. The non drive side hub and wheel has very little play on its axle , perhaps a 1/8 inch and seems to run fine.
While the drive side hub slides back and forth and seems to be creating un... Read more >>
So today I got a flat tire (unrelated, it was a nail, extracted, repaired. All good) and when I pulled over to try to find what caused it, I noticed that my rim was rubbing the brakes the way it does when it's out of true because of a broken spoke.
The spoke is fine. It's the RIM that's been damaged, and that has damaged my calm some. I took it to my usual bike shop, guys are pros, figured they'd have an answer, no such luck. They gave me vague language about how it "looked like it h... Read more >>
We have a hand me down bike which has been in the family for 30+ years. It's original ower is now in her fourties!!! I'm attached to this bike because the memories I have with my dad riding it.
It has rusted underneath the chrome coating it had so it now all pitted.
I was wondering, can I respray the paint back onto the rim?... Read more >>
I have a very annoying creaky/rubby noise that I cant shift although I have narrowed it down to the rear wheel and not the bike.
I have a Giant Propel Advanced SL 0 Aero Race Road Bike 2016 3 months old and 1,000 miles with the SLR 0 Aero wheels 55mm.
The noise noise only happens (always takes 10 mins to warm up) when I'm seated and putting some power down uphill or on the flats. Now I know its not the BB as I have put my friends Mavic rear wheel on my bike and my SLR r/wheel on his Scott and he gets the same noise on his bike. He's 60kg and... Read more >>
Someone just gave me a 32" cruiser bike. Yes, it's a boxstore bike, but they were kind enough to give it to me and I appreciate their generosity. The back tire has a gash in it, and I'm having a hard time finding a replacement. I'm contemplating downsizing the wheel set to a more common size. Seems like it will work as the bike is very simple: single speed, coaster brake. Spatial reasoning isn't my forte so sometimes I look at things like this thinking they will work, only to find out I'm mistaken. What do I need to think through on such a swap? Thanks in advance!!!... Read more >>
I have a 1997 Giant Ferrago. Great bike, bulletproof. I was changing the rear tube, and doing a bit of lube to both wheels. When all was said and done, I had a left over spring that I think came off the bike. But where?

I just tuned my '76 Schwinn cruiser up for spring, and after riding as far as my daughter's bus stop my rear wheel has shifted over far enough that the tire is hard against the frame. So I readjust, tighten it back down, and in the same time my wheel has shifted again. It's gone as tight as it can. I'm wondering if the mounting brackets of the fender are causing the nut to slip. Perhaps moving them to the inside of the frame would help? Any suggestions?
Edit: It only seems to be the drive side that slips. The chain is loose and the tire presses against the non-drive side under the... Read more >>
