14. How to Replace a Broken Spoke
Demonstrates a single spoke removal and installation.
IMPORTANT: Nuts and bolts on your bike should always be tightened to the manufacturer's specifications.
If you break a spoke on your wheel, the best thing to do is stop riding until you can get it repaired. However, sometimes you simply have to keep riding, in which case you can keep the broken spoke out of the way by twisting it around an adjacent spoke.
Spoke Removal
To replace the damaged spoke, first remove your wheel and then the tire, tube and rim tape. Then remove both ends of the damaged spoke and nipple. Spokes usually break either at the nipple or at the hub flange. If it’s a rear wheel, you’ll have to remove the cassette or freewheel first.
Spoke Installation
Insert the new spoke and gently flex it into place, using the other spokes as a guide. When installed properly, the spoke pattern should be consistent all the way around the wheel.
I personally recommend using linseed oil to lubricate the nipple threads before threading the nipple on to the spoke using a screwdriver or nipple driver.
Gently pre-bend the new spoke by pushing down on it at the hub flange, and then tighten the nipple using a spoke wrench until it has the same tension as the rest of the wheel. Check this by plucking the middle of the other spokes on the same side and then compare them to the sound of the new spoke. Now you can true the wheel as demonstrated in the last tutorial, and re-install your rim tape and tire.

04/28 Rear hub problems
I just got a bike and there is quite a bit of play in the rear wheel and a clicking noise when I pedal backwards. I assume this means I need to overhaul the rear hub. My question is how detrimental is it to ride in this condition, and how do I know if my hub is fixable or I need to replace it? Thanks. Paul... Read more >>
04/23 What type of wheel do I need?
Hello chaps I'm just an ordinary guy. I don't know anything about bike repair but I'm reasonably intelligent. So why am I finding it so hard to fix my bike? Nothing else in life seems to be this unnecessarily complicated. I am trying to fix up my old Marin Kentfield (2006) hybrid bike. It has a bent rear axle. I figured I would buy a new wheel as well in case something in there is broken too. I checked to see what sort of wheel the Marin Kentfield uses but nothing on the Marin website or anywhere else on the internet seems to know. I checked the existing wheel to see if there were any us... Read more >>
04/17 Rear Wheel Rubs on Brakes When Pedaling Hard
Whenever I stand and pedal - say up a hill (or crank up the pedaling leverage in some way) my rear wheel rubs against the brakes. I had originally thought it was my lower bracket, but a repair there has eliminated that as the problem. I also believe I have confirmed that it is the wheel "twisting" a bit by opening the brake a bit so as to increase the distance the brake pads are from the wheel when not braking. I also can "wiggle" the wheel back and forth when the bike is at rest and make it touch the brake pads. This is without the wheel spinning in any way and while I am leaning on the bike...

04/14 Skewer seems to long for rear dropouts
okay so just recently i bought an old road bike. My friend gave me this extra wheel for it but it didn't fit on my bike.i have heard of there being spaces from the dropouts and the rear tire where you need to add spacers. but on my bike the skewer seemed to be a little bit to long for my rear dropouts. like i cant fit the rear wheel in at all. Also the gaps in the dropouts where you screw the wheel on seem to be to small to fit the skewer in. so do you think that the wheel is just to big for my bike? sorry for my lack of bike terminology, and sorry if this is a dumb questions...

03/26 Skewer broken inside hub
Through a non-profit bike group I work for I acquired a used 700c Mavic wheel with a Shimano 105 fixed-gear hub. It seems that a small part of the old quick release skewer rod is lodged inside the axle. What is a safe way to remove it, if it is at all possible? I attempted tapping a skewer rod against it with a hammer but with no luck. Besides this the hub and wheel are in excellent shape.... Read more >>
03/23 Sturmey S2C cone adjustment
Hi All, I just got a Sturmey Archer 2 speed "kickback" hub. I love the concept and everything about it, except that it's very rough. When in low gear I get all kinds of pops and clicks, and sometimes it'll jump momentarily into high gear and back to low on every revolution... very hard to ride. The coaster brake is weak too, but that's doesn't really bother me (even with all my 185 lbs on the brake it gradually slows to a stop). I've read that people have eliminated noises and shifting problems by adjusting the cones. Can some of you experts coach me on how to do this? Any help will be gr... Read more >>

02/07 700c front + 26" rear?
I have a hybrid bike frame which was designed for 700c wheels and I also have a 26" rear wheel with 8 speed hub gears and roller brake, which I was thinking of putting on it However, the front forks have fittings for V brakes for the 700c wheels, so I was thinking of sticking with the 700 c wheel for the front. I have heard that putting odd wheel sizes on bikes may not be a good idea due to changing the frame geometry/handling/steering etc. My main use of the bike is for commuting and I prefer comfort over performance. Does anyone have any input, please? Thank you very much.... Read more >>
