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.
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 >>
So I have this lovely ti tourer with shimano xtr hbm960 hubs, and I am hoping to service these hubs. I see a metal cap on both ends of the hubs both front and back and the metal cap has a space that looks like I can put a flat head screw driver into to pry it off, it has no flats like the other cones I've dealt with. Can't find how to on the internet. Has anyone dealt with these hubs?

I have a 1987 Cannondale racing road bike that I have been using to ride on crushed stone and paved trails. The wheels have worn out and need replacing. I was wondering if I could get a slightly wider wheel that could support a wider tire. The crushed stone makes control a bit hard at times. I am looking for more stability from the bike.
I like the feel of the bike and am very comfortable with the road set up. I would rather not have to buy a new bike.

I was wondering if someone could recommend to me which removal tool is needed to remove this freewheel? I recently broke a couple spokes and the freewheel needs to be removed to access the hole to put a new spoke in. I put the ruler there to measure the diameter of the space, it's about 35mm-ish. I was looking at park tools freewheel recommendation site, but don't see one that would necessarily match. Would the FR-6 or FR-8 work? Thanks!

I got this from Consumer Reports. It effects disc equipped bicycles from 1998 -2015. Including major brands like Cannondale, Dimondback and Specialized.
The quick release wheel lever can come open and get jammed against the disc brake.
To see if your bike is effected go to: quickrelease-recall.com... Read more >>
Hi, I'm having some trouble reattaching my daughter's rear wheel to the frame after fixing her flat. It's a 20" wheel, single speed, with linear pull brakes. I have it reinstalled and with what seems to be a good tension on the chain, but it's rubbing the brakes and it's a real chore to pedal.
I had to go through this just last week when my son did the same with his. It was a learning curve (lots of youtube help) but I got it right on the third try. But he has horizontal forks where the axle goes on, so it seemed to be just a matter of getting it the right distance and holding it ... Read more >>
Just bought a new pair of 700c hybrid wheelset with an inside rim width of 19mm. I have tried to fit schwalbe 700 x 40c tyres on them but the tyres just pop out from the rim when inflated. It seems to be a loose fit. Somebody please advise.

I bought a wheel set of Mavic Crossroc. The rear hub came with a 12 X 135 set up, but I need to a 12 X 142 mm so I got some adaptors and I have disassembled the hub but I can't figure out how to remove the actual end cap on the axle. Do I have to remove them, if yes how ? If no do the 142 mm just slides over these caps ??

I removed my rear wheels on my single drive ancient Miami Sun trike, right rear bolts to bearing, left wheel has a nut on end of shaft ... I had the wheels trued, and tubes and tires replaced ... tires are .25 wider than original. Now when I try to ride it is quite a bit harder to pedal. Is there a proper tightness for the rear wheel axle nut ? or is the wider tire the culprit ? I just assume I did something slightly wrong ... Thanks... Read more >>
I need some advice on whether to repair or replace my rear wheel. I have a decent single speed road bike that a friend built together for me. I let another friend borrow it, and he decided it was a good idea to ride 6 miles on a flat (lessen learned not to let people borrow your stuff). So in doing so, he busted a spoke, and bent the rim. I removed the busted spoke and got a new tube. Its rideable but the wheel wobbles a bit, not terrible but enough to be annoying. Im not an experienced mechanic so I was wondering if this is something that is worth taking to a bike shop... Read more >>
Question for you cycle experts. Would tubeless tyres fit on a magnesium alloy wheel? Please see link below of 26" magnesium alloy wheels that i am interested in.

How can I remove the hub end caps from my front wheel? The wheel is a 2014 TBC Revolution Trail 27.5 with 32 spokes. I tried pulling them off by hand and with a pair of pliers but was unsuccessful.
The reason I'm doing this is because I noticed movement when I grip the wheel and move it side to side. I suspect the hub bearings and would like to remove the caps to have closer look and possible replace the bearings.
Here are some pictures of the wheel and hub:
Hello to everyone,
I'm new to the forum and I want to congratulate with all of you for your excellent work! Now we can go to the serious stuff:
I'm not an expert of bikes and I'm trying to fix my old TREK. The freehub is broken so I decided to replace it. It was not easy but, finally, I removed it from the bike. Now I have two questions:
1) I'm not sure I removed it correctly because the back of the freehub is different from what I can see online
2) if I removed it correctly, can someone tell me what kind of freehub is this? I want to buy the replacement <... Read more >>
