Hi Calvin, great video, I like your videos always with explanations on how it works before how to do it. The left crank blot of my bike is lost. I like to find compatible bolt and fix it myself. How to figure out which bolt? The arm is ISIS drive type. I guess cap size and axel thread size are important. I see online stores carry blots for M8 and M15 etc. but I don't have knowledge on what they mean and how to determine the blot I need. Thanks.

ISIS bolts come in two sizes. Either an M15 or an M12. You can determine this by measuring the ID of the hole in the spindle. When you measure, the measurement will come out just shy of 15 or 12. This is because you are measuring the minor diameter and bolts are labeled by there Major diameter. I hope this helps!

You can install a 2-piece where there was a three piece. It will mean replacing the entire system. The bearings will be different, and the spindle comes on the arm. You need to get one made for the width of bottom bracket shell you have. Measure the width, likely a 68mm or 73mm. -Calvin

Cannondale Si cranks have a special removal tool that is required. There are tricks around this so that you can use a common crank puller. If you find a washer that will fit the ID of the crank hole so that it the washer will push on the spindle then you can use something like our CCP-44 or CWP-7 with the large swivel foot.

Yikes thats a tough one to figure out. What is the model number that is just inside the crank arm? It should be something along the lines of FC-3300 or FC-3303 or something along those lines. The crank arm length should be in the same section of the crank so a 170, 172.5 or 175 will be right above or below it.

My crank has a nut on both sides. I think the crank itself is one that goes through both sides with bolt like arms or whatever. The left side has a large ring that tightens down to the frame to keep the shaft in place. That has 3 groves in it at 3 points. Not sure which tool is used to tighten or loose that ring. Other than using a wedge and hammer which seems very inefficient.

@parktool

The cotter pin system is not so good, as you have learned. The pins are made of softer steel, and will often deform when hit with a hammer. Sometimes there is not a happy ending here. Begin by getting the bike inside and warm. In fact get mild heat on the crank like from a hair dryer. You are hitting the threaded end, yes? If the threads are bent, you will need to snap them off, and then use a punch to reach inside. Even this is not always good because you can expend the pin as you strike it, making it harder to remover. It can often come down to drilling out the pin. Good luck.

@parktool

4 жыл бұрын

Cranks vary in length depending upon brand/model. From 160 to 180, in small increment. The crank is a lever, so the longer the easier to turn. But it is also further around that circle. Shorter cranks can be turned a faster RPM easier. The knee also articulates (bends) more with longer arms, and that can be an issue for some. The body has levers as well in the femur lower leg, and these of course can vary in length. Then add in riding style, it is not a simple choice. But it can be. If you are new to riding, ride what you got for now.
