## What is Retül Fit?

Retül is an inspirational, immersive and modern experience for riders. Our technology is used to collect and analyze data to help retailers and fitters advise riders and help them make the best product decisions to increase comfort, prevent injuries and improve performance.

We've been partnering with Specialized since 2012. Together, we've been able to take Retül technology to new heights, and along the way, we've also elevated the precision of Specialized's Body Geometry products. This relationship has also brought a tremendous opportunity to Retül, as we've been fully integrated with Specialized's pro-level athletes and teams. Now, we can take what we've learned from working with the world's most demanding riders and apply this knowledge directly to riders of all experience levels and motivations. 

Based in Boulder, Colorado, we've specialized in bike fitting technology and training since 2007. In that time, we have performed thousands of fits and taught hundreds of training courses around the world. We have helped bike shops, fit studios, performance centers and medical professionals implement Retül technology services into their businesses. Here, we've also been able to work with the most talented team in the industry, employing everything from software development to shipping & receiving. And now, we're situated in a brand new Innovation Center here in Boulder, which allows us to both grow and expand upon exciting new projects and groundbreaking innovations.

### 1/5 — Unusable

*2026-03-12*

The V8 software doesn’t work too well.  I have been unable to do a Retul fit since I was trained because the harnesses and Zin won’t register with the VCB.  When attempting to change the channel, it never seems to find one.  Bring back V7.

### 2/5 — Still waiting on a few things

*2026-02-19*

I too feel like there are a few bugs that need fixing and the overall appearance could be updated. Still not getting left side pedal calibration. V7 was a more like-able bike fit system. Fix the interface, set up more data documentation instead of “full” or “limited”. Shop employees will like it, but scientists need more. What happened the ROM analysis? We had to get a newer IPad to use the cameras that was supposed to allow physical assessments.

### 3/5 — Vantage 8 or Retul Premium

*2025-07-24*

I feel like there are still a few bugs to fix with data collection. Finding the Pedal Spindle is the least consistent task. I also don’t like the interface, which is no longer user friendly for clients to view. The data collection of V7 is also gone which as an Exercise Physiologist collection of data is important to me. The data collection for joint kinematic is still good, but the interface is Excel spreadsheet looking.

### 1/5 — Not ready for prime time

*2024-08-12*

Lots of in consistencies.  Not user friendly in operation..
