Would you buy a Stages power crank or a 4iiii power crank for R2500 less?

 

I can get a stages for R14500 or a 4iiii for R11000.

 

Should I buy the 4iiii?

 

Both are Dura ace crank arms.

Which DA are you looking for though? the 9100 at CWC is R10k

Yup, other than bragging rights the numbers dont arent as big a deal as consistency is.

For that amount of money spent...I would rather then use hrt...that's just me

 

Hopefully you use a chest strap  :thumbup:

Variable Accuracy of Wearable Heart Rate Monitors during Aerobic Exercise

 

Results: Across all exercise conditions, the chest strap monitor (Polar H7) had the best agreement with ECG (rc=.996) followed by the Apple Watch (rc=.92), the TomTom Spark (rc=.83) and Garmin Forerunner (rc=.81). The Scosche Rhythm+ and Fitbit Blaze were less accurate (rc=.75 and rc=.67, respectively). On treadmill, all devices performed well (rc=.88-.93) except the Fitbit Blaze (rc=.76). While bicycling, only the Garmin, Apple Watch and Scosche Rhythm+ had acceptable agreement (rc>.80). On the elliptical trainer without arm levers, only the Apple Watch was accurate (rc=.94). None of the devices was accurate during elliptical trainer use with arm levers (all rc < .80).

Conclusion: The accuracy of wearable, optically based HR monitors varies with exercise type and is greatest on the treadmill and lowest on elliptical trainer. Electrode-containing chest monitors should be used when accurate HR measurement is imperative.

I have used HR based training for 10 years as an Elite road racer.

I have been using power meters since 2012.

 

My training hours have come down. 

Training has been more specific.  More concentrated.  Better quality.

I am fitter and stronger than what I was with less hours spent on the bike.

 

Yes, there are lots of variables. 

 

I am very glad I train with a power meter and not with hr anymore.

 

If I had R20k for a set of wheels or a PM, I'd go for the PM.

 

But that's just me.
