14 - 16 - 18 - 20 - 22 - 24 - 34 Teeth
"Alpine" design, with closer spacing between most of the sprockets for efficient cruising, and the huge 34-tooth "bail-out" gear for the tough hills. This setup looks funny on paper, but works great in practice!
It is generally good practice to replace the chain when you replace the freewheel.
We recommend the SRAM PC-870 chain for use with this freewheel.
This freewheel will index with any Shimano-type 7-speed shifter, but does require a wide-range (touring/mountain) rear derailer.
This freewheel uses the Park FR-1 extractor.
Are you sure you need a thread-on freewheel, not a cassette?

I bought one of these about a year ago, and got well, about a year out of it.. happily it gave plenty of warning before giving up,(clicking) so I replaced it with a used freewheel I had kicking around. . . That being said the used freewheel is also starting to skip, so maybe there is something else going wrong.. I will probably get another one of these, as they are not that expensive, yet i would happily pay twice the price to get something that 100% built to last.

Well, the way I have this 7 speed freewheel is actually quite embarrassing. I bike every single day to school and I'm in 9th grade, but I do all my bike work by myself, because I like to learn and that is how I have done so, not to mention saving me $$$$ on the process. My bike is a weird front suspension Royce Union, with 26 inch rims. I suppose that the previous owner changed the gear changer, derailleur and the rims,(This I know because my bike has "Six Speed" stamped on the metal)and the new rims are hard as rocks, and the freewheel is that Shimano 34t whatever with 7 gears and a HUGE 1st gear that I LOVE because it has so much torque for heavy loads and hills. I don't mountain bike but I do 8 miles every day on a lake path but obstacles and an ocassional "experiiment" get done easily and smoothly by this bike, and undeniably by the freewheel itself. The best about this thing is that it makes my otherwise nasty bike, into a really smooth riding masterpiece! I have compared my Royce with some weird gray/black expensive bike a friend has and I can guarantee it goes as the other bike. I have put well over 1000 miles on that bike, maybe double, and that freewheel is only just asking for replacement. I intend on putting the same model freewheel on because it was so effective. By the way, my bike... I found it by a dumpster... and it is better than any other bike I've had.

This is a very versatile and reliable freewheel. I've had one on a Diamondback MTB for 5 years, and it has held up well. The 34T Megarange sprocket keeps you pedaling up steeper climbs (you might not set any records, but it beats walking). I'm replacing a 14/28 FW on my FrankenBike with this one. Tips--Make sure you've got a long-travel rear derailleur, and that your chain is the correct length. If you are a DIY'er, check out [@] for bike maintenance.Megarange freewheel options are getting more rare, so I'd snag one up as a backup.
