Online Bike Fit: everything you need to know
An Online Bike Fit is a remote fitting option designed for riders who are confident making their own adjustments, or for those looking for guidance around a Zwift Bike setup. This service provides expert guidance, analysis, and recommendations, without the need for an in-person appointment.
When done properly, an online bike fit can be a very effective way to refine comfort, efficiency, and position. However, because adjustments are made by you, it’s important to understand what this service includes, what’s required, and where its limitations lie.
Who an Online Bike Fit is for
This option is best suited to riders who:
Are comfortable adjusting their own bike - this is super important as there are risks associated with over/under tightening bolts (Please note that by booking an online bike fit, you are accepting this risk and Baseline is not responsible)
Understand basic bike setup and measurements
Have access to a stationary trainer and video analysis capability
It is not recommended for new riders or those dealing with complex injuries that require hands-on assessment.
What’s Included
Your Online Bike Fit includes:
A detailed pre-fit intake covering your bike setup, riding history, and goals
Video analysis of your position while riding on a stationary trainer
Recommendations for saddle height, setback, reach, saddle angle, cleat position, and cockpit setup
Clear explanation of why changes are suggested and how to trial them progressively
Note: Stack changes are likely to be provided as recommendations only, due to the complexity of these adjustments. This does not include Zwift bikes.
All guidance is tailored to your riding goals and comfort, with a focus on efficiency and injury prevention.
What You’ll Need
To get the most out of your session, you’ll need:
A stationary trainer for steady, repeatable riding
A stable camera or phone setup to capture clear footage
Appropriate bike tools to make adjustments - a torque wrench is strongly recommended
Time and patience to trial changes gradually
Accurate setup and clear footage are essential for meaningful analysis.
Important Considerations and Risks
Because this is a remote service:
All physical adjustments are performed by you
Baseline provides guidance and recommendations, but does not physically handle your bike
We recommend using a torque wrench to ensure bolts are tightened correctly
Baseline cannot accept responsibility for issues arising from incorrect installation or adjustment
Stack changes are provided as guidance only and are often best completed by a qualified bike shop, as they may involve cutting steerers, reconfiguring spacers, or more complex hardware changes.
How to Get the Best Results
Online bike fitting works best when:
Changes are introduced one at a time
You allow your body time to adapt before judging the outcome
You communicate clearly about how each change feels
If something doesn’t feel right, adjustments can be refined, or we can discuss whether an in-person fit would be more appropriate.
When an In-Person Fit is Better
An in-person bike fit may be more suitable if:
This is your first bike fit or you’re new to riding
You are unsure or just damn intimidated on how to make adjustments yourself (totally fair!)
You’re dealing with ongoing or complex pain or injuries
You want real-time testing of multiple components
If you’re unsure which option is right for you, feel free to get in touch before booking.
