what type of front derailleur works best with this crank? what if you add a 24 th granny?

A mountain bike front derailleur would work best. Adding a 24tooth granny ring would be fine also.

This front derailleur is a triple, for mountain or hybrid bikes. It might "work" on your road double, but it is not a good choice.

I'm not sure about he SIS but I would think so. I don't know the model of my front derailleur but it has two gears as my bike is a 14 speed and it worked great for me.

Maybe. The derailer travel is determined by your cable control mechanism. My bike has three stations where the cable is 'click-locked' into place. Other bikes have a lever that is tightened just enough to hold it in place while still allowing for shifting gears. So, in other words, I would look for a front derailleur designed to work with your bike.

Yes, we have the crank style too and it works just fine. I bought 2 of them.

Standard for bikes made today. The older the bike, the more chance it is 1/2 though so be careful if you're looking to put some pedals on your grandpa's bike

your current derailer should work, you may have to move it up a bit on the frame, but should be no problems

Howdy... all rear derailleurs need a hanger. You can buy bolt-on hangers if you don't already have one on your frame. Inespensive, but likly to break if you do a lot of rough riding. I'm not sure but I think this one will only accomodate up to about a 37 tooth chain ring. Check on Shimano's site though. My own rear cassettes only fo up to either 37 or 39 teeth.

I'm using my 12-30 with an Ultegra short cage, and it works just fine, this despite the fact that when I originally set it up the opinions expressed at the time said it would not work. I believe even Shimano had a company opinion that it was not appropriate to run that combo. That said, you are still at the mercy of "try it and see if it works." If it were me, I'd take the chance, but you have to make the final call. As in my previous answers about this set-up, I'd remind you to not give up if it seems it won't work initially. Chain length is critical in being able to keep the idler pulley from contacting the 30 tooth cog, and I think I may have messed with the stop screw as well. I wish you the best of luck!

Honestly I wouldn't spend a penny on this. Had its week and it broke on me. No hard riding either only just casual. If ur looking for a good derailleur, I'd start at shimano 105. My road bike has 105 competes and I have not had a problem at all

This is for a double chainring crank.There is a trim click,that slightly moves the front derailleur to reduce chain noise,when shifted to extremes.Not made for triple chainrings.

my bike is an old Raleigh MB with friction shifter and lowered grearing on the front for hilly biking.Everything on my bike is Shimano except the front crank(34 tooth). Lowering the gearing was like getting a new bike. Hope this helps.

The main thing is, SRAM REAR derailleurs will only work with SRAM REAR shifters, and vice versa. You can never use SRAM with Shimano in the back. It doesn't matter in the front.

I believe the photo is errant. What I received was a 7 speed. You definitely don't want to substitute an 8 speed on a 7 speed application. You'd have too much slack in the shifter cable (in position 8 on shifter) even if you adjusted the deraileur stops to avoid the chain falling off, and an annoying dead spot gathering up that slack when shifting back into the lower gears.

I think I would try a 28. Doubt if the 24 woud be enough for a 125 racing 2 stroke

I have the ultegra short derailer and switched from a 11-28 tiagra cassette to the 12-30 ultegra casette. It maxes out the derailer but has worked great for the Pittsburgh hills. Just completed the DC to PGH ride with that setup.
