How to Straighten a Bent Disc Brake Rotor

Hello, I've had my bike from teenage years in the garage with the wheels off for a few years now. Put it all together and instantly remembered why it was in storage. The handlebars either move without the wheel turning or the handlebars get REALLY hard to turn (with the wheel ofc). Its a matter of maybe a quarter turn on the top bolt from loose to tight, there's no inbetween. I think when I was y...

In the past I have had a lot of punctures. When they happened, I patched the tube, but the holes in the tire were so small, they did not need patching. After many more kilometers, rubber started coming away around two of the holes in the tire, exposing the chords. If I did not do anything, a rock could cut the chords, destroying the tire. I wanted to get more use out of the tire. I cut patches fr...

Hi, So I bought a used Schwinn Meridian sight unseen online auction for $59 & drove 8 hours round trip to get it. It appears to be brand new actually. When I got it home, the next day I checked out my score. When I sat on it and pressed on the pedals, they moved but the bike did not. I inspected the bike and realized that whoever put this trike together, forgot to put what appears to be ...

I had a previous incident with my bike, and the front brake got bent. Now when I try to use the front brake, it is very weak (when I ride the bike and fully depress the front brake, the bike does not stop quickly). I tried to fine-tune the disk brake caliper (I did it many times before), and it looks good and tight, but the front brake. What could be the reasons for this?...

Hi, I've had my Giant Defy for two years now and have done about 4000 miles on it. I keep it clean and generally only ride in dry or damp conditions (never pouring rain). Apart from a potentially stretched shifter cable (won't go in highest gear despite adjusting barrel adjuster and limit screws) the bike rides fine. I keep on top of basic maintenance, cleaning, checking for chain wear etc... an...

Hi there how do i tell if my front deraullieur needs to be replaced on my hybrid it has a ton of play back and forth....

Hi, I got a cracked shimano DI2 front derailleur (see picture attached). I try soldering it but no luck (probably don't have the right solder). Any suggestions on how to fix that please? Thanks   20230206_170038.jpg (Size: 47.7 KB / Downloads: 35) ...

Hello, I’ve got an old set of square taper FSA tempo cranks (2x) that I want to swap from a single speed 120 OLD bike to a 1x10 135mm OLD one. Any tips on how to calculate the spindle width for correct chain line? I can’t find anything for that model on the manufacturers website, and i don’t think measuring the one on the single speed will work with the different chain line....

First time adjusting a headset and I'd like to get it right. Brand new giant reign with a carbon frame, that I do not want to damage I finally have the preload set to where there is no play but I'm concerned that it is to tight... Stage 1- obvious play/clunk Stage 2- no clunk, but if I lock up the brake and push and pull hard, I can feel some very slight movement Stage 3 - no play or movemen...

Awhile back, I was able to hack a 7 speed freehub body and get an additional speed out of it by using a 9 speed cassette with the narrower spacing. Note that these older freehub bodies are 7 speed exclusive. They do not typically have the space to fit a larger cassette on them. To do this, I took a 9 Speed Dura Ace 11-23 cassette and I simply removed the final combination cog from the back, then...

Ciao. I know that some bike riders overexaggerate the 'cleaning part' and wash (or spray) their bikes at least once a week. I know, it's mandatory after a muddy trail ride. But I'm thinkging more about daily commuters. It gets dusty here and there, but how long is too long without a shower for a bike? For a bike that rides almost every day....

I made a video of what my bike is doing. Can someone please watch and help? https://youtu.be/NTu-831CuGM...

Looking for advice. I have repeated problems with my D-lock sticking. I've used standard light bike oil which then leaks all over my hands when I handle the lock. I have some 3-in-one PTFE spray: would that be better?...

Hi everyone! I hope you're enjoying a great start to 2023. I'm curious to hear your go-to method for getting a chain truly clean. I don't mean, just looks shiny or is good enough for a quick clean after a ride. I want to know what you do when you want to get every last morsel of ground-up, link-destroying, roller-eating, tooth-gnashing crud out of your chain. The Best Chain-Cleaning Recipe Ever?...

Obviously, this doesn't speak for them all, but they certainly might fit! And not even just barely (as suggested by some sources), but with a lot of room to play with. This is another GT Tempest frame that I recently purchased. It's originally a 26" alloy touring bike. As you can see, there's lots of head room, and plenty of clearance to increase the tire size up to probably 38c—maybe even 40c....
