Featured User Review: Sigma Sport ROX 9.0
by WRM

Price: $160.00 at Tree Fort Bikes
Overall Rating: 5 of 5
Value Rating: 5 of 5

Bike Setup:
Giant Carbon TCR-1/Jamis Supernova CX. Ritchey cockpits. Dura Ace and Ultegra groups. Selle San Marco Regal and Regale saddles, Mavic wheels, Look Keo and Shimano SPD pedals.

Favorite Ride:
They’re all good!

Summary:
Perfect computer for my purposes. Just downloaded the v2.0.2 software and can’t wait try it out. Looks like Sigma upgraded quite a bit and addressed several of my “wish list” items.

This is my third ROX 9.0–the first was replaced by Sigma no charge because of a software glitch with the early models that made some of them lose 40 seconds each time they entered sleep mode. The second unit again was recently replaced because the mounting tabs on the bottom wore down. Again, no charge and excellent customer service. Turn around time in each instance was less than a week. Software allowed me to reload previous computer info and set-up data with no missed beats. Had to replace one cadence sensor after epic weekend of rainy riding, but cost was reasonable — hopefully an anomaly.


I have no need for GPS so all the other functions in addition to the basics (plus on-screen heart rate) were just what I was looking for. I have logged over 8,000 miles between two bikes with many saved trip and log data entries. As a race organizer, the log function has been great for mapping out course information (especially elevation and %grade) for the longest point to point race in Michigan (Le Tour de Mont Pleasant). Highly recommended for a do-all computer if GPS is not important to you. Once familiar with the operating logic, navigating the computer menue on and off the bike if very intuitive. Based on the performance of this unit, I bought a ROX 8.0 for my spouse.

Strengths:
Intuitive menue navigation, amazing number of feature-rich functions (which are fully customizable), wireless transmission w/o signal loss, downloadable trip and log options for after-ride analysis, good software support, excellent customer service, reasonable price for a computer this versatile, neat unit demo feature on Sigma’s web site (try before you buy). Many other strengths too numerous to mention in this limited space.

Weaknesses:
Little things here and there, but nothing major at this time.
