Has anyone tried the 12-36 with Apex medium lenght rear derailleur? I know it only supports 32 teeth but I'm wondering if there is any room. Thanks!

If you manage to pull it off, I don't recommend it. There is nothing wrong with a long rear deraileur. A good XT or XTR, if not fallen on will last forever.

Not sure. I'm only around 6 feet tall and about 200 pounds and broke the rear cassette on my first ride today. The friend I was with is shorter and lighter and broke his rear cassette on the exact same bike, on his first ride also. The size itself is good, just wondering about the actual product quality now.

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!

not exactly...this is a 14 tooth (small cog) which means your top speed will be different and it is possible that some of the intermediate cogs could have different tooth counts also. Plus you want to make sure you have a thread on hub as this is. (screws on and off). If yours isn't a screw on then you need a "cassette" type.

For most instances the medium option will work. Shimano actually calls them long cage and super long cage. The long cage model is usually used on 29ers with triple fronts and 36 tooth rear large sprockets but a medium will work on a 42 tooth 1x conversion.

My set up: sram red compact crank and sram 1050 12-32 cassette...works fine, no issues, has been on my bike for over a year...though I did not determine the correct chain length, I had my LBS do it. : )

28 isn't much more than 26... it only needs 2 more links of chain. same derailleur should be fine in my opinion (used to work at a bike shop) but if you shift to the LARGE chain ring in front and the 28 cog in back (a gear you should NOT be using anyway due to extreme chain angle) then you may find your chain is too short and the deraileur arm on bottom will be pulled really far forward. When you change cogs, if your old chain is really worn (1000's of miles riding), it's a good idea to get a new chain too, and a new chain would be sufficiently long. you'll need a chain tool to cut it to length though (again make it just a little longer than your old chain). 28 isn't much more than 26... it only needs 2 more links of chain. same derailleur should be fine in my opinion (used to work at a bike shop) but if you shift to the LARGE chain ring in front and the 28 cog in back (a gear you should NOT be using anyway due to extreme chain angle) then you may find your chain is too short and the deraileur arm on bottom will be pulled really far forward.

I can't completely answer your question. I have a Tiagra derailleur and I must say it took some time to adjust so that the 28 didn't hit the derailleur. But after some adjusting, I'm very happy with the performance.

13 - 15 - 17 - 20 - 24 - 29 - 34 Teeth. Personally, I think this is too wide a range and went with 14 - 32T which has 14 - 16 - 18 - 21 - 24 - 28 - 32 and does not have quite as big a jump between the gears.

I use this derailleur with a 7 speed MegaRange cassette. The problem I have, is that the rear derailleur mounts with that "arm", thus causing the derailleur to hang low. This, in turn, causes the chain to hit my centerstand style kickstand in certain gear combinations. Annoying, but certainly not fatal. I will switch to another centerstand.

My chain rings are 22,32,42 and I find I can go anywhere I want with my 8-speed 32-12, which is no longer made. You may find it on eBay. By the way, if you have a rear wheel with an 8-speed cassette, you can use a 7-speed cassette with a spacer to replace the spot where first gear usually is. Sometimes the 7-speed cassette will have rivets that stick out but they can be ground flat and work fine. All my bikes have 8-speed hubs, so I can use either 8-speed or 7-speed with the spacer. I don't like 9-speed and up because of the narrower chain.

Any Shimano / microshift / sunnrace rear derailleur will be controlled by this shifter. If derailleur description says 7/8 or even 9 speed it will work. The "speed of derailleur" is really its range of movement, ie how many cogs wide it can span. 6/7/8 all use the same chain because spacing is the same. When I had mounted these A050 thumb / paddle shifters on my sons 8 spd roadbike, we could only use 7 cogs, so we adjusted High or Low limit screw to exclude top or bottom cog. If u have flatbar these are a great choice. If u have road style drop handlebars, consider the related Shimano A070 Brake Lever Shifters.

Yes, you just won't be able to shift to either the biggest or smallest cog, depending on how you set your limits. But why not just use a 7 speed cassette?

... ciao: first, these are NOT specific to a 9-speed rear deraileur, as they given as replacement for the X7 8-speed component. i would suggest you research the SRAM website for definitive information. in my research, it seems there are both new and old models with the 'same' identifier, but 'different' capabilities. SO, failing that, locally, they are said to work. your mileage may vary.

I have a 9 speed Shimano cassett on them. I beleive anything close to that will work. Not sure about spacing. Skewers came with them. I am happy with them.

Thanks for replies. So would I select the 1 1/8" threadless 300 from the pull down selection?This is the only place I could find any specs:http://www.roadbikereview.com/cat/latest-bikes/hybrid-bike/trek/7200/prd_291124_5672crx.aspx
