Can I use a 7 speed derailleur on an 8 speed cassette?

Yes, you can use a 7 speed derailleur on an 8 speed cassette. The extra cog on the cassette does not require a different derailleur, so you can save yourself some money by reusing your old 7 speed derailleur. Just be sure to check that the derailleur can handle the wider range of gears on the 8 speed cassette.

Can I use a MTB derailleur on a road bike?

Yes, you can use a mountain bike derailleur on a road bike, but there are a few things to keep in mind. First, mountain bike derailleurs are designed for wider gear spacing than road bike derailleurs. This means that you may need to use a spacer on your road bike frame to properly position the mountain bike derailleur. Second, mountain bike derailleurs typically have longer cages than road bike derailleurs, which may cause the chain to rub on the frame when in the innermost or outermost gears. Finally, mountain bike derailleurs

SHIMANO Ultegra 11 Speed Road Pulley Wheel Kit Review:


The first-generation Tiagra jockey wheels deteriorate and exhibit side-play. This causes sloppy shifting, which is frustrating because it causes the car to shift crisply up but not down, and vice versa when you make an adjustment. Because the sealed bearing on the Ultegra wheels allows for more precise alignment, All of my shifts are exact, quick, and dead-on after installation and a small modification to get the alignment correct. For not much money, a good improvement.



SRAM XX1 Eagle AXS Upgrade Kit - Rear Derailleur, Battery, Eagle AXS Controller w/Clamp, Charger/Cord Review:


There is no greater way to shift than this. extremely swift and fluid. The programmable shift paddles are awesome. My configuration allows me to shift three gears with a lengthy press. Additionally, you may programme it to move to the cassette's end on a long press. The capability of having different data points appear on my Garmin bike computer was a pleasant surprise. There are many more, but I have it configured to display the current gear and battery level. You can also set up an SRAM account and check how much time you spend in each gear during each ride. After 20 or so rides, or roughly 280 miles, the battery is still at the top bar.



Juscycling Derailleur Hanger for KONA Stinky Dawg Coilair Coiler Howler Stab Fire 25 Review:


We have a rare Liotto bicycle that was produced in Italy. When it was provided to us, the derailleur hanger was broken or missing. I was unable to find the part anywhere. Directly contacted Liotto, who informed me that they were the only location to purchase it because it was made specifically for their bike. $20 plus $40 for shipping After abandoning the project for a year, I made the decision to browse through every hanger on Amazon to choose one that appeared to be the closest, then just grind it down on a grinding-wheel till it fit. I've decided on this, and it's the PERFECT match out of the box! See the images below! Attachment fastener also performs admirably.I hope that anyone looking for help will find this review!



SRAM GX Eagle 12-Speed Rear Derailleur Review:


A Shimano XT long-throw clutch with a 1 X 11, 32-plate, and 11/50 cassette was installed. But I wanted to change it to Sram. The Sram 1 X 11 system is advised for cassettes with up to 42 teeth. Consequently, I used this tensor GX for 12 speeds along with an 11/50 cassette and an 11-speed GX pulsator. After properly adjusting the tensor's movement tops, it works well. after being verified using the cadena holgura tool, remains in place.



Flex Derailleur Hanger 94 for GT,Aggressor, Avalanche, KHS, Timberline, Kestrel, Kettler, Mongoose Review:


I have no idea why it became $14 all of a sudden. They must have thought, "Hell, we should be making more money on this stuff," encouraged by the five-star reviews. It's a shame. After receiving this, I had assumed I would need to purchase another one, but it has held up really well. Like many others, I assumed I would have to replace the entire derailer, but it turned out to be just this tiny component. The derailer isn't much more than this tiny piece of pot metal, which is kind of strange. Anyway, it's been working wonderfully for 6 months and has outlasted the original. Good fortune!



Dymoece Bicycle Rear Hanger Derailleur Extension for 40T 42T 46T 50T Cassette Review:


Utilized this to increase the cassette compatibility of a 10 speed Campy Chorus RD, which was said to have a maximum cog capacity of 26. The largest cog is no longer rubbed or rolled by the pulley wheels. I double-checked the placement of my hangers and they are perfectly straight. Although the threads appear to be a little sensitive, everything is installed without issue. I may need to clean them up with a 1.25 TPI M12 thread chaser. An affordable replacement for the Wolf Tooth Roadlink; if necessary, I'll provide an update on its long-term durability.



AUTUT 2 Pcs Universal Derailleur Hanger for Cyclocross Bike,Hybrid Bike, Mountain Bike, Road Racing Bike Review:


The delivery was really prompt, and the items fit the bicycle perfectly.

How do I know if my rear derailleur is GS or SS?
