I have a triple crankset, the biggest plate has 52 teeth. I don't understand what mean the sizes. Is 34.9mm right for 52T?

Obviously the "xxT" is the number of teeth around the various gears. Separately from that is how the desrailleur is mounted: either a braze-on or a clamp-on. If a clamp-on style, the diameter of the down-tube is given as either 28.6mm (narrow/small tube), , 31.8mm (medium /mid size tube) or 34.9mm (large tube). You need to select the correct size for the frame's down tube. They are not interchangeable. Some of the Shimano desrailleurs come with a sleeve to build-up a 28.6mm to a 31.8mm. Hope that helps.

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.

That staggered bolt pattern is for flywheel/ flexplate with 168 teeth. The straight across bolt pattern is for the smaller 153 tooth. So depending on what size flywheel/flexplate you're using, will determine if this will work or not.

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. : )

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.

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

the first number (68mm) is the width of the this cylinder that holds the bearings and the axle that the cranks are screwed on. the second number (110 or 113mm) is the measurement of the axle itself. to find out what that measurement is you need to rip the cranks off your bike. they have special tools for that just in case you don't know. with a "caliper gauge" you can then easily measure the axl. but if you so far that you unmounted the cranks then you might as well remove the bottom bracket(also with a special tool). on that BB itself there should be a label with all the measurement on it. hope it helped a little.

Hi Joseph. I originally bought the 9800500 size chains to use on my PT Cruiser, which has 205-55x16 tires. (A little shorter and wider than yours but pretty similar.) They were really, REALLY tight and a pain in the ass to put on. I recently bought a new set and went one size larger, I think they're 9800600. They are much easier to put on and still fit nice and snug. If I need to replace them again that's what I'll get. And another word of advice for you - I find that these chains work well but you want to be careful to always avoid spinning the wheels. I was trying to climb a steep hill in very icy conditions that were just too much for the chains to cope with. The wheels spun, the car slipped sideways just a few feet and that caused the chain on one wheel to slide off to the inside of the wheel. It got torn up on the suspension, no damage to the car but that's why I bought the new set. Obviously, I like them enough to buy a new set but I'll be more careful with them now and I'd recommend everyone else should be too. Tom

There are two sizes of pedal shafts, 9/16 and 1/2 in. Yours is probably a 9/16. To be absolutely sure take off one of your pedals and measure the diameter of the shaft were it threads in to the crank arm. Secondly, buy a better set of pedals than these, both sets I purchased began making noise soon after use. Both sets went into the trash.

what size your looking? 1 or 2 mm not make to much deference, i think, the chain has some space, in my case i was looking for 110mm then i found one for 113 and is working, i did a race 50 miles and was good no problems at all, good lock, just in case keep looking .........

The only problem you >might< run into is clearance between the forks and the tire or between the fender supports and the tire, but honestly, it should fit. I've run 26 X 2.50 tires on my trike that came with 26 X 2.125 tires originally, and while the clearance between the forks and the tires was snug, they worked...and were a lot more comfortable at operating pressure. Hint: Keep your tires near or at maximum pressure for the smoothest ride. It's counter-intuitive, but that's how it is.

there's a 17 tooth freewheel for a 1/2 inch chain and a 17 tooth freewheel for 3/32 inch chains, typically the 1/2 inch chain is for true single speeds and BMX bikes, 3/32 inch chain is typically used for 7, 8, 9, 10, and 11 gog freewheels, multi speed bikes. A 17 tooth freewheel for a 3/32 inch chain would usually be used for multi-speed to single speed conversions. If you use a 3/32 inch chain just make sure your crankset gear and freewheel are 3/32 inch compatible.

The first number is the number of teeth, the second is the measurement/diameter of the chain ring. So, a 46/110 will only fit another 110.

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.

Hi, that model of Trek probably was offered with more than one crank set. You need to measure the "BCD" or bolt circle diameter. That is the distance between the bolts that would hold on the largest chain ring. 104 BCD is very common.

I'm running the bash guard on a 33t chainring and could see up to 36t, but not 40t.

the specs on that area a 44 to 48 tooth outer ring, the main thing is also its a 9 speed, I had a seven speed rear sprocket, didn't work for me, so be sure and check your rear sprocket. Then look for a 3 x ?, whatever you have, then you should be ok.
