Dial In Your Ride.​

Fit Comes First — Or At Least It Should. At Cassette Fit Studio, we often meet cyclists who’ve spent thousands on a beautiful bike that simply doesn’t fit their body. That’s where we come in. Bring in your current bike — we have the tools and expertise to fine-tune your fit and make that bike work for you. Shopping for a new ride? We’ll help you find the right size and fit before you buy, so you can choose a bike that matches your body, your goals, and your ride style. 

Everyone Is Important.

Our Services

1

Cassette Video fit 

The Cassette Video Fit is a personalized bike fitting experience built to improve comfort, efficiency, and power on the bike. Using advanced video analysis and a full physical assessment, we fine-tune your position to reduce strain, increase performance, and help you ride longer and stronger—without pain.

2

Tune Up/Metric Transfer fit

Our Tune Up Fit is for existing clients who need small adjustments as their body and riding change over time. If it’s been over a year since your last fit or you’re experiencing a specific issue, we recommend a full Cassette Video Fit.

Our Metric Transfer service is for returning clients with a new bike. We’ll transfer your existing fit measurements and position to your new setup for a seamless transition.

A guided, personalized fitting experience for Assos cycling apparel (bibs, jerseys, etc.), designed to make sure you don’t guess on sizing—especially with technical brands where fit really matters. This appointment lasts roughly 45mins. If you need more or less time, give us a heads up so we can accommodate.
