How to Check If Your Bearings Are Worn

Hello all, I have a old Antelope 820 in nice condition that has a broken (right) shiftier (Shimano 200GS SIS 7 S). It appears that these old parts are not readily (or cheaply) available. Has anyone swapped out these shifters with a more current model without changing the derailer(s)? I don't want to spend alot as the bike isn't worth much I just have a hard time trashing it since is a nice bike ...

Hey everyone! This is my first time repairing this bike. I’ve done basic maintenance (new tape, tubes, tires)... but then the wheels were stolen! I really enjoy the aesthetic of this bike and I’m hoping the repairs will be possible. I’ll definitely need some direction on what parts to look for and how to approach this. Here is what I’m working with. Nishiki Performance Equipe Sport See...

So i just bought a new 2019 bmx ive had it for a little over three months. Should I regrease the bike so it can feel fresh or should I leave the old grease? it's dumb but I'm still new to working on my bike. I have most necessary tools to work on my bike. Any other type of advice for the future or something like that would be immensely appreciated. Thank you ...

Hi all, New member here . I just bough a new bike and yesterday was my first ride. I noticed a sound when in my 3th or 4th gear (3rd and 4th largest sprocket) . Today I tried to determine the noise and it seems to be because the chain does not seem to fit perfectly on sprockets (if inspected, you can see small gap between chain and sprocket, causing a "click" when pedalling). I checked the usual...

A recent purchase of an Elektra 7-speed cruiser came with a Megarange freewheel. I didn't like it, so today I swapped it for a regular 14-28T freewheel. The second lowest geared cog has 24 teeth. The lowest had 34 teeth. That's a huge jump from one cog to another. I found that in a headwind, when I dropped to the lowest, I had to pedal like crazy just to get up to walking pace. And because of thi...

Took an old 28" front rim from a friend who would otherwise throw it in the garbage. THe rim came with 700 Hutchinson tire and I had to change its inner tube, before putting it on my old road bike. Then came the evening nightmare .. tire was SUPER tight and did not want to come off. I have changed many tubes, but this was so far the toughest tube swap mission. Fingertips hurt and Hutchinson did no...

Hi I'm building up a mountain bike ready for when the summer gets here in the UK, I got given a pair of Marzochhi Bomber 55 front forks that came with a Tektro Auriga Comp hydraulic brake. Wanting to keep the brakes matching I bought a secondhand new old stock rear Tektro Auriga Comp brake, when it arrived it looked in good condition, I had to order a bracket for the frame to allow the caliper t...

I purchased this bike for $75 and it wasn't riding well so I decided to take it all apart and make it new again. I am having the most difficult time removing the fork and pedal cranks (I think that's what they are called). The top of the fork has a black circular piece that I am sure needs to be unscrewed but it won't budge. I have tried using a pipe strap but it just slips. Using a set of pl...

I own an old road bike from the 80’s I quite like. To this day, all the original parts are still on the bike, except the last mudguard that broke this year. The wear and tear is getting more noticeable lately, especially the wheels and the breaks. Shifting is not as smooth as it used to be, but it’s not a major concern. The wheels are probably the biggest problem since the wheel ring is not to...

I recently rebuilt my old 86 Schwinn and replaced the chain at the same time. On the small cogs, when under pressure, the chain seems like it's too short to reach the next cog. I used a 6/7/8 speed chain, but have a 5 speed freewheel. Is my freewheel worn, or am I using the wrong chain? Or, something else?...

Hello My rear break lever is stuck open on my Specialized XC ,also the break pads are in the breaking position on the disc even though the lever is open. Please help...

Oh well, another move of the seemingly and endlessly mobile "skunk works". I had to move in short order due to a friend wanting to make the house into an "air b&b"; good luck with that! Never thought that the garage would be a big rental concern; but I am concerned about my stuff getting damaged or lost, so in a rental space while I reorganize my house for the new/old projects. Managed to fit ...

I suppose I should wait until daylight to do the job. My new lever shifter came a couple of days ago and tonight the handlebars arrived. Maybe I'll just remove the brake levers, twist shifter, grips, computer and light and then get some sleep. Well, it's stripped down. Maybe I'll just put the bars on and then get to bed. Yes, they look good but they'd look better if I just put the new lever shift...

I'm dealing with a V-brake boss that has been slightly mushroomed. Does anyone make a tool to machine it down to spec, or do I just need to go at it with a file? Please disregard, I just realized the post is replaceable. Duh....
