How to Clean and Lubricate a Chain

Would there be any issues with one less tooth on the high gear as regards shifting or otherwise?...

Just bought a new bike. It has a KMC H700 8speed chain and I am would like to know if, when the time comes and the chain must be replaced, I could replace it with a Sram PC 850 8 speed chain that I have on hand....

The chain is slipping on my MTB when I'm on the middle chainring and smallest sprocket on the back, but only when I put a lot of force on the pedals.  I replaced the chain last year along with the 7 speed freewheel and the middle 32T chainring. I've probably cycled only 1000 to 1500 miles since and tried to only oil the chain when it was clean, so I'm not sure whether it is excessively worn (have...

Hi, All! I recently got a broken bike from one of my friends, and want to fix it as a fun project. Seemingly its chain is off from the rail and completely distorted like a helix, so it needs to be replaced. Also, rear derailleur is shattered into two parts, each has a gear, not sure if it can be repaired as I'm a total newbie, so I decided to buy a new part for it as well. However, I don't know ...

Hi, my chain on a 2016 Specialized fatboy keeps getting sucked into the tire and comes off when I am in the top gear coasting. I have had multiple bike shops look at it and they say that those bike are not made to be in the top gear which sound ridiculous to me. It also been suggested that I change the front sprocket from a 28 to a 32. Also the chain measured fine. Any suggestions?...

I fitted a black 105 5800 compact chainring set (50/33) when I built my new bike. I prefer the 50 chainring cos, on our flat terrain, I can push it, but I can't push a 52 0r 53.  However, I would like to change the 33 inner ring for a 42.  I have found some rings with the same PCD, but they all seem to have some qualifications which I don't entirely follow.  Is there a straight forward way to ...

Hi, I have the following issue on my bike (see video): https://youtu.be/XtuR7BI_7SU When stopped at traffic lights I need various attempts at putting the pedal at the correct hight to set off. Is this to do with play in bottom bracket or another issue? I have this play in bottom bracket: https://youtu.be/ikX9hNyDs6g It's an old bike so do not want to spend much money on it. I can live with th...

I'm having an issue on my CX bike. Which is shimano with 38/48. On the last 2 rides when I'm in the lowest gear on the cassette my chain drops off the small chain ring. It doesn't happen on the 2nd from lowest gear on the cassette. I decided that maybe my rear mech was limited enough so perhaps was pulling the chain off at an angle. Therefore I played with the Lo limiter screw and indexing ...

I have an older frame with an ultra-6 freewheel.  When the rear wheel is removed the stays measure 122.78 (hub is a 120 for the ultra-6).  I can cold bend it out to 126, I'm sure, but do I need to if I just put a regular 6-speed freewheel on?  I'm not sure how tight that would be as far as the chain scraping the frame.  has anybody tried it?  Has anybody bent a 120 out to 126 or 130 without p...

I recently picked up a Park CC-3.2 to put in my portable bike tool-bag (12 inch ruler won't fit).  With it one of my chains that measures fine with the ruler, fails, even at the .75 side.  Reading on the subject states that the CC-3.2 doesn't take into account roller wear, which the Shimano TL-CN41 does. So, I took a popsicle stick (perfect thickness) and shaped it to press the roller nearest th...

Hi all. 1st time post. I am unablr to remove the cassette from my rear tyre. I followed the easy tutorial on bikeradar but havent managed to get any success. See link to pics of my cassette and the lockring i bought. http://s1067.photobucket.com/user/Nexus62/library/Mobile%20Uploads I think i know where i went wrong. The lockring i purchased didnt fit properly, so i just used a spanner to remove...

i've recently started riding my bike for exercise. was going well for a couple weeks, but a few days ago the chain on my bike has been slipping off of what i think is the gear shifter. it is very annoying and i haven't been able to ride my bike because of it. Edit More info: i have a Schwinn Ranger 10 speed. the gear only slips like that in high gear. it does not slip while in low gear. i have...

Hey Guys, Have a BMX bike that the single speed freewheel is worn out on. The problem is that the freewheel was installed backwards. So, the notches that the freewheel tool would grab on to the freewheel to remove, are on the inside of the wheel next to the spokes.  There are two small holes that are 180 degrees apart from each other on the outside of the freewheel.  Is there a tool to use th...

I have an older(vintage) bicycle, it,s a 7 speed using suntour radius parts. I want to change out my chain ring. Some say compatible with 9 or 10 speed, does it really matter? If I buy the same rings as 52/42 with the right BCD....

I have a Bianchi with SRAM Red components.  The cassette is a 11-28 10 speed.  The crank is 53-39.  I recently put on a new SRAM 10 speed chain and the chain skipped while riding when I was applying heavy pressure to the pedals.  I then put the old chain back on and the problem went away.  It feels as if the skipping is coming from the cassette rather than the crank.  I tried it again with y...
