The Cycling Tech Brief: the cycling tech that actually matters today — and whether to update, wait, or ignore.

• Garmin backtracks on CIRQA paywall: live heart rate during workouts will be free — Hold off on judging CIRQA until the Connect Mobile update lands — once it does, live HR should be free and the band's core value proposition is restored.
• Strava's $11.99/month developer API fee is live — club endpoints die September 1 — Your device sync and personal data downloads are unaffected — but if you use third-party club tools or segment apps, check whether they've migrated ahead of the September 1 deadline.
• Shimano RX710: Pontoon cleat system and dual BOA at $300, splitting the gap between trail shoe and race flat — Worth monitoring — specs are compelling on paper, but wait for independent long-ride and fit reports before committing, especially on the DYNALAST 2.0 last if you're between Shimano widths.
• Zwift subscription systems go dark for ~5 minutes on July 26 — active riders unaffected — Nothing to do — if you're an existing subscriber, ride as normal; if you're trying to sign up in the early hours of July 26 UTC and hit a wall, wait 5 minutes and try again.
• TrainingPeaks publishes summer heat-training guidance as platform transitions under new Garmin ownership — Follow the heat guidance if you're mid-season in hot climates; keep an eye on TrainingPeaks platform news as the Garmin integration takes shape over the coming months.
