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...

The bike, new, was $199 from an Amazon dealer, and it came with a load of great reviews and very few negative ones. That should be a warning to anyone looking for a new bike; the shills are out there. If anyone buys one with the idea of putting it together and going for a ride, they would be disappointed. Walmart bikes are better. Seriously! I knew that it would need some work because you do...

hello I, I just bought a e-trike that has a shimano derailer: Tourney RD-FT35A , is there a higher quality replacement ? thanks tee...

New to forum, just signed-up, after reading an entry about constantly loosening crank-arm fixing BOLTS. In my case, my original BB, uses crank-arm fixing NUTS (original equipment, not jury-rigged), instead of BOLTS. I’m “dating” myself, but I’ve had this bike since new. I’m constantly re-tightening the nuts, every other ride, or worse, at times after a long ride. I have had difficult...

The most common bikes with gears use a freewheel hub. Some bikes with gears have other types of hubs. Axles may bend and break in freewheel hubs. Heavy riders are more likely to bend and break axles than light riders. People riding on rough tracks are more likely to bend and break axles than people riding on smooth roads. Axles are more likely to bend and break in hard tails, than bikes with r...

So I'm totally "new" to biking in a sense, I used to bike as a kid and picked it back up when I was around 20-23 or so (I'm 30 now). I had a Schwinn I bought from target back in 2011 or so. Took a fall once and I didn't want to spend money at a bike shop to fix it, so it just rode weird from then on. Then it got flooded in a hurricane and has just rotted in my backyard ever since. I just picked u...

Make your own strong, inexpensive, freewheel removal tool, using a car wheel nut. The most common bikes with gears, use freewheels. There are other gear systems for bikes, but they are used on less bikes. The tool I will describe is for the most common type of freewheel, as shown in the picture. There are freewheels which require different tools, particularly on older bikes.   free...

On one bike I have either the bottom of the range Shimano rear derailleur, or an imitation copy of the bottom of the range Shimano rear derailleur. The spring tension is weaker than many other rear derailleurs. The chain sags more than it should. With a derailleur like this, the chain rides up on the sprockets more than it does with a derailleur with stronger spring tension. This results in the s...

Hi Folks, Posted this on another forum as well. Hope to get the assistance here. I'm not a very handy ebike enthusiast. Don‘t really know the inner workings of an ebike, I just like riding them. Anyway, was riding my Core-5 that has around 1200 miles on it, and suddenly it made this strange grinding sound every time I engaged the throttle or PAS. Visited Ride1up’s support page and read...

We have just changed a gear twist grip as previous broke. Have fitted a shimano 7 speed But now it jumps a gear in the middle. 1st fine 2nd fine 3rd fine But when change to 4th it jumps to the fifth sprocket so then twist gear just goes to 6th But is actually 7th on sprocket. It does the same going down gears, If you just turn twist half way through clicks 3rd / 4th it will go onto 4th. But a...

Hello there, I had managed to replace my inner tube and outer tyre successfully, however since then I have been trying to re-fit my rear tyre back onto the frame to no avail. Initially I thought the axel was at an angle. I have undone the nuts and bolts many times, rode the bike, then either the tyre starts rubbing with the frame, or the pedals become really stiff to rotate. But today I have r...
