At Big & Tall Bikes, we’re on a mission to create more comfortable, efficient, and powerful bikes for bigger cycling enthusiasts. Whether you’ve got ultra-long legs or a larger build overall, you deserve a bike that provides a smoother ride; a bike that’s built specifically for you. All of our large bicycle cranksets are designed to be much longer than the standard 180mm crank arms. Here, you can find bicycle crankset parts with a maximum length of up to 220mm. Learn more about why you need longer cranks and how they can make a real difference to your everyday rides!
As specialists in the big and tall cycling industry, we're against scaling up standard bikes for bigger riders. When manufacturers choose to scale up a frame, they don’t always consider how this would change the bike’s proportions and affect the rider’s comfort.
We built our philosophy on the belief that muscles and joints work best when they are operating within their optimal range of motion. Just like short riders shouldn’t force themselves to stretch to reach the pedals, tall riders shouldn’t be squeezing onto a too-small bike. While we can create a bike entirely from scratch, we also offer component customization if you just want to change one thing about your bike. With our custom bicycle cranksets, you get the most out of your movements.
How to Find the Right Length
If you’re wondering how to find the right bicycle crankset length, you’ll need to start by measuring your inseam. Since the ideal crank length is between 21% and 21.6% of your total leg length, you should multiply your inseam length by both 0.21 and 0.216 to find the best range for your needs. Once you know the correct crank length, you can shop our bike crankset types, including touring, road, and mountain biking varieties.
From bike crankset types to crank bolts and bottom brackets, Big & Tall Bikes is here to help you with all your custom cycling needs. Shop our selection or reach out to us today for additional assistance!
