How to Adjust V-Brakes

]Hello.. First post ! In trouble already.. It's years since I last did bike maintenance and then it all seemed to easy.. I've just bought an old Dawes Shuniah mountain bike (£5) that's been very neglected. The rear hub bearing are dry and I need to repack with grease. Looks like the axle is slightly bent as well. First hurdle is the cassette removal (without special tools ) The lock nut is diff...

Hey guys so I have ~50 years old Cosmos SuperCorsa and the only problem with it is that the rims are bent to the center. I want to replace them but I can't find the exact same brand at a good price. The wheels are from Campagnolo. The bike is 700c with 36 holes. The inner width is 13,5mm and the rim height is 18mm. Are the last 2 measurements not required or it should be exactly as the ones I have...

  IMG_0838_resized.jpg (Size: 195.96 KB / Downloads: 15) Howdy folks! Was hoping you all can help me out. I am going to send bicycle parts and tools to help people in Malawi. Was sent this image and told this type of bike is the "work horse" of transportation. From what I can tell they seem to be 1 speed with narrow tires, maybe 26 inch? Obviously pedals might be good too. Any thou...

Could someone help me out? I recently purchased a new single speed bike sprocket. I put it on my bike and I had to make the chain smaller. Anyways I got everything put together and its as if the bike doesn't have enough tension when you pedal. like when you pedal it feels like the chain isn't even on. the cranks spin almost to freely....

So I have a couple of questions that I hope someone in this group might know about or have experience with. This is for my Schwinn Meridian 7-speed trike. 1. Are the derailleur chain and the drive chain the same type? Obviously they're different lengths; and I assume the derailleur chain is a typical 7-speed chain. But what about the main drive chain? Same thing? Or is it a standard single speed ...

I have these Chinese freewheels. On the inside are ridges which are supposed to be there so you can use the tool to remove it. With these freewheels, the ridges are very low. I have a tool, also made in China, and the ridges on the tool are also very low. So when trying to use the tool to remove the freewheel, it does not grip properly, and it can't be used to remove the freewheel. The metal on ...

Hello everyone and thank you so much for having me! I have an older Columbia 3 wheeler adult tricycle and she has a differential, somewhat like a car. I wanted to open up the differential for cleaning and oiling but cannot find any info on her, as to how much oil to add, and where the oil fill point is. Can anyone help me in this endeavor? I'd really love to get her going but don't want to ris...

does this noise mean anything? The bike was not used and left outside for a long time. The freewheel sprocket spun free in both directions. After removing it and dripping oil thru it in both directions it appeared to work fine. Once reinstalled it still works fine, but does make this noise when I stop peddling. With bike upside down and rear wheel spinning freely i can also fell the noise as a vi...

Schwinn Boundary bottom bracket bearing let go. I would like to upgrade them to sealed bearings. Threaded frame bottom tube 35 mm nut thread od. x 73 mm wide....

Hello all. My name is Andrew, and I reside in sunny Bognor Regis, UK. I have been an avid BMX rider my entire life, but my body has taken a battering and I now have arthritis creeping in and if I am really lucky* I will also inherit my mother's osteoporosis. *yeah was being sarcastic. No other form of comedy funnier etc lol. Any way, when my body started to fall to bits and I had a bad BMX wreck...

I have a 1975 Hutchins road bike and want to, if possible, fit a modern crank set, say a Campy Centaur Compact, to the bike. Can this be done and would the existing 1975 front Campy derailleur work? Thanks, Dorsey...

I'm trying to find a 3 spoke or 5 spoke wheel for my virtue hybrid bike. All I can find is for road and fixie bike only.   Screenshot_20220522_213714_com.android.chrome.jpg (Size: 30.77 KB / Downloads: 10) ...

I just installed a new set of brakes on a bike at a hostel I've been staying at and I can't get them to work right. First, the front brake lever has a ton of lateral play and they don't have much power when applied. Second, the rear brake arms won't release. It doesn't seem to be an issue of the brake nut being too tight, I can loosen it to the point where I can easily move the caliper by hand a...

Just wanted to drop some positive encouragement for taking your spindle crank out and getting some fresh grease in the cups and on the axle regularly. This will dramatically improve the performance of your drivetrain. For example on how often, I had fully overhauled my bike back in March, when I converted it back to urban street from the snow conversion. It's only May, not even 300 miles on it sin...

First, I'm new here and also Thanks in advance for reading and helping me out. I'm a casual bike rider who lives in a large city and enjoys getting out for a ride in the summer to enjoy the beautiful weather. I don't have a very fancy bike (Trek) but it get's me around just fine. My Problem: I don't know if this is normal on all bike's but I have to put air in my tires every 2 weeks. I've replaced...
