I threw this very same Sunlite 103mm BB on an old Trek for the purpose of converting to single speed.Now depending on your frame..You may need a somewhat longer Spindle or BB.Or it could possibly be a Front derailleur adjustment issue.Good luck! Eddie

As important as verifying that it has square bottom-bracket fitting, which it likely has, is making SURE the gear-teeth/ratios numbers match..whatever your old one is, it will create problems and more work if you try to fit one smaller or larger number of teeth, the front derailleur will not be in the right position and adjustment for a start...if your largest cog is 42T, you will be easier off with another with 42T, best to get the middle gear the same such as 34T or 32T, as well.

There are only three adjustments on the derailleur itself. They are the high, low and B. If the ratios are the same, you torque the locknut to factory specs and have cleaned out all the grime than you do not have to adjust a thing. That said if you don't know how to adjust them, I suggest that you let your local bike store handle the job. Two weeks ago I went over a berm and onto the side of a hill when I derailed. I could have been killed but ended up very lucky and just laughing while on my butt with my bike in the air still clipped in. I needed to adjust the limit on the derailleur for non-cross chain high tension operation. There are only three adjustments on the derailleur itself. They are the high, low and B.

Hi Matt, I do not understand your question. I bought this crankset for an electric bike project. The previous crankset was geared to low.

usually one piece cranks (part of the gear) take 1/2 inch; cranks that bolt to the bike are usually 9/16 inch; if the pedals on the bike are not marked you can always call the bike maker's 800 number and ask (which is what I did on one of my bikes) and if you give them the model they can tell you. These will fit just about any bike, road, mountain, comfort, or commuter; they are just a little wider and longer than stock pedals. I have a comfort bike(1/2 pedals) and a commuter bike (9/16 pedals) that I have used these on for two years with no problems and they really grip the bottom of the shoes well. usually one piece cranks (part of the gear) take 1/2 inch; cranks that bolt to the bike are usually 9/16 inch; if the pedals on the bike are not marked you can always call the bike maker's 800 number and ask (which is what I did on one of my bikes) and if you give them the model they can tell you.

i think either version has a stated maximum of 44t chain ring. it is for triple cranks

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. : )

Shimano M952 has a BCD of 112mm. This chainring will only work with 104mm BCD cranks.

The crank will only work on the left . If you restring cable to other side there will be no guide for cable.The crank shaft will not reverse because of gear location.

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.

If its a standard frame it 68mm.Its a Euro frame it 71mm.And the width is determined by the crankset.If your using your old crankset( peddels and gears)Just measure the length of the old one that's your width. With crank arms removed.If your buying a new crankset use the width recomended by the manufacture.68 mm most common size for BB

Sorry, but this question is beyond my limited knowledge. I can tell you that I paired it with a 11-34 cassette, and it is not quite up to the worse case small-small chain ring combination (my chain goes slack, but I never use this). That may be me, with too long a chain? Anyway, next time I would choose a long cage, not this medium cage, just to be sure. Amazon did not or does not offer the long version.

It's designed to replace all of your rings on the crank. Since you say middle ring, I'm assuming you're running triple. It's not designed to just replace the center gear.It is designed to switch your bike from a 3xX to a 1xX. I'm currently using my narrow wide with an XT crank, it required the spacer kit. Not sure if XTR is the same or not, but I'm assuming it will be the same.

It works with a 3 speed crank if you only want to use two of those speeds. That is what I did, but I always use the two tallest gears and never the low. They have good adjustability, with a 2 up and 3 down setup. If you set the two up positions correctly, using the half down can allow you to avoid having your chain rub on the guide, but is not enough to allow for use of all three gears.

All 6, 7 & 8-speed rear gears/cassettes use the same 3/32" chain width. Chains are shipped with enough length for almost any bike. You need to cut them to length with a chain breaker tool (which you really should buy if you don't have one). Be sure to leave enough length to allow shifting into the largest front chainring and the largest rear cog/gear at the same time (even though that's not a very good gear to ride in).

You can combine this freewheel with any Crankset you want. Determining factor is the length of the chain.
