Mutant Bikes – Bionic Cranks with the Spliner System Explained

Leave a Comment

Mutant Bikes put together a video showing you how their Bionic Cranks with the Spliner system works…

Thinking about getting a new set of BMX Cranks? Here’s a video showing you how the Bionic Cranks from Mutant Bikes works. These cranks use Mutant’s patented Spliner System that uses a split axle design that has a spacer with threads inside the bottom bracket. The system uses compression from a long bolt to pull both sides into the threaded spacer for a strong, tight fit that spins smoothly. This video shows how the cranks go together and how the Spiner System works. It’s a unique concept, but it looks real clean and strong.

“MFOBMX Company developed a new crank system, were the axle is divided in half and becomes an integral part of each arm, the tightening is made inside with just one 8mm allen bolt and a Spliner® Boss with 48 spline that also works as a spacer between the bearings. SPLINER® is a patented system, tested several times during years and approved. Thicker arms than regular cranks and shorter axle to prevent twisting, also the crank shape, was designed to don’t hit the ankles.

How To Use A Crank Arm Puller

Leave a Comment

It’s Tuesday, so it’s time for Brant Moore to drop a new tech tip. This time around he shows you how to use a crank arm puller on BMX cranks!

If you have rode BMX for a while, there’s a very good chance you have had to take your cranks off at some point, or install a pair of cranks on a new frame. While, installing a pair of cranks isn’t exactly rocket appliances (Trailer Park Boys, anyone?), it can be a little tricky and using the right tools for the job make life a lot easier. If you have ever had a pair of 3-piece cranks, there’s a good chance you have either used, or have seen a Crank Arm Puller. Now, the tool isn’t completely necessary, but it exists because it does make things a hell of a lot easier when it comes to installing or removing BMX cranks. One reason many people don’t use them is because they don’t know how it works. Brant Moore put together this detailed video showing you just how to use a crank arm puller to remove or install a set of BMX cranks. Hit play, take it all in and then remember to use the right tools for the job!

“A crank puller is a tool that can make putting on and taking off bmx/bicycle 3 piece cranks a quick and easy task. Especially compared to the alternative of using other tools, aka the wrong tools for the job.

In this video I demonstrate how to use a crank puller to install and remove bmx 3 piece cranks.” – Brant Moore

Does crank arm length on a BMX bike matter? It does! Here’s a video where Brant Moore discusses it…

It’s that time of the week for Brant Moore to do a little tech tip for you guys. This time around he is looking at how crank arm length has an affect on a BMX bike. Brant talks about the different sizes, the difference between longer cranks and shorter cranks and much more. This is great info if you’re considering getting new cranks and you aren’t quite sure what size to go with. Hit play and take it all in!

“There are many different crank lengths in the world of bicycles.
The question is, does crank length matter?

In this week’s Tuesday Tip, we answer that question through the help of some insight from Profile Racing as well as a scientific study of power output in varying crank lengths.”

Profile Racing – Tech Tip: 19mm VS 22mm Cranks

Leave a Comment

Thinking about getting a new set of cranks, but you aren’t sure if you should run 19mm or 22mm spindle?

This weeks Tech Tip from Profile Racing takes a look at the difference between their classic 19mm Race Cranks and their 22mm Column cranks and what size you should run based on your riding style and preference. This talks about a few of the Pros and Cons of both sizes and gives you examples of what each the riders on their team run for cranks. You can check out the tech tip on the Profile Racing Website!

One thing they don’t cover in this is the 24mm crank arm size that a few brands also offer. This size has been pretty commonly looked at as overkill for many riders, but there are a bunch of guys out there that could benefit from that larger size as well. Either way, 19mm, 22mm and 24mm are all options. 19mm is the most common and 22mm being the second most common option for the riders that are harder on cranks.

What do you run? Let us know what size and why in the comments below!
