How to Install a Rear Derailleur

Hi everyone, I wanted to learn how to fuse, connect, or solder two U7 LED headlights into a 1-to-2 Y-splitter. Below are some pics of what they look like. I have an electric kick scooter, and one of the front headlights has blown out. So I am planning to buy two (2) new sets of U7 headlights and a Y-splitter. My idea was to cut off the ends of the 2 female Y-splitters and solder the wires to the ...

Hi there, I recently bought some new wheels for my brand new specialized sl8 expert which runs sram rival axs. Everything is great except gear 12 (smallest cog) is now rejected (red and green LED flashes) in large ring. All other gears run fine. I notice as well that in the large ring it allows me to be in gear 1 which is cross chain? Is that normal? Any ideas what I need to do? Is it a limit sc...

Been going back and forth adjusting limit screws and tension. 7 Speed. When in the largest cog, the Shimano gear shifter reads 2. The chain will not shift to the smallest cog. When in the 2nd smallest cog, the shifter reads 7. So, no clicks remaining to get to the smallest cog. Any suggestions to resolve the issue. Thanks!...

Hi there, I'm a new member here....thanks for having me....you look like a nice, friendly and helpful bunch! I've been riding bikes as far back as I can remember, starting on my blue trike with big fat white tyres. I'm now mainly mountain-biking and commuting to work, with a bike for every situation! Over the years I've always done all my own bike maintenance and repairs and recognise now how com...

I bought a schwinn boundary 29" and the axle is missing does anyone have or know the size axle i need to get it together?...

Hi to all. I'm wanting to fix up an old MTB and want to use three colors (black for the front, yellow for the mid and red for the rear). I didn't want the colors to just abruptly meet but instead blend into the next. I'm unsure what this technique is called and the net provided no clues. I guessed that it's a "fade" or "blend" technique but it's a mystery how this is done. Can this be done via ...

I thought I would do a thread about how to do a quality refurbish on a bicycle that will be a good user trouble free for quite a while. The scope of this refurb will not contain content about dealing with battle scars it may have endured in its lifetime, primarily because the bicycle is merely an example of a solid platform to build from (vintage lugged frame circa 1990). Purchased for $15us ...

Hi, I have a new 2023 Trek Dual Sport 2 (gen 4) . It has a 2x9 drivetrain with Shimano Altus shifters. The red needle in the shifters window is reading off to the left. In my posted image this is how 5th gear is displayed and 6th gear is actually very close to reading 7th gear and so forth. Is there any way I can adjust this indicator a little bit to the right so it’s properly sitting spot on ...

I have an e-bike and every time I switch gears, it makes a loud cranking noise whenever I'm pedaling. Because of this, I normally keep it in gear 6 or 7, and it doesn't make any noise at all. Just only in the initial start-up of pedaling, and then it's fine, but every time I switch it back over to any lower gear or high gear settings, it sounds like it's gonna pop and it makes it loud popping cran...

I've read that a bit of negative camber (tops of the wheels tilt inward) is normal for most recumbent trikes, but the Catrike info I've read says that they're supposed to have neutral (0 degree) chamber. After I put two Schwalbe tires on my Catrike, I noticed that the front wheels each have a bit of negative chamber - and that the only causes per Catrike are "If your Catrike Dumont wheels are not...

Has anyone replaced the front axle of the Schwinn Meridian trike with a quick release axle/hub? If so, any thoughts/instructions? I am looking at some of the 'replacement' kits on Amazon that are supposed to replace a through axle with a hollow axle that has the quick release skewer inside.... but I don't know anything about them or if they're safe? Or hard to replace? If anyone has any experien...

I'm about to replace the rear wheel on my bike. The new wheel has a quick release, and I'm wondering if, since the axle is hollow, it would make it more prone to bending than the fixed bolt axle. The new wheel is the same brand as the old one (Weinmann 519, 26"x1.5), and they appear identical in all respects except for the axle. My question is, would it be better for the sake of durability to use ...
