Most serious cyclists ride their easy days a little too hard. A new study suggests that costs you fatigue and recovery without buying any extra fitness.

20 trained amateur runners, matched for volume, trained for six weeks either at the top of the moderate domain or 10 to 15 percent below it. Both groups improved by the same amount, but the higher group paid more in perceived effort and recovery. In cyclist terms: don't ride your endurance work at the top of zone 2 thinking it earns you more.

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

• Strava launches official MCP connector giving paid subscribers direct conversational access to their full training history via Anthropic's Claude — Monitor — if you're a paid Strava subscriber and want AI-assisted training analysis, the connector is live now and worth experimenting with; just know it's read-only and Claude-only for the moment.
• CPSC warns riders to immediately stop using Ridstar Q20 and Q20 Pro e-bikes — 11 fire incidents confirmed, manufacturer refuses recall — Don't buy — if you own a Ridstar Q20 or Q20 Pro, stop riding and charging it immediately, remove the battery, and contact your local household hazardous-waste program for disposal.
• Florida man sues Amazon and Chinese e-bike brand Bigniu after battery explodes during charging, causing severe burns and a residential fire — Monitor — if you own a Bigniu BG10 or any high-wattage moped-style 'e-bike' bought through Amazon without UL or equivalent certification, stop charging it unattended and check for any CPSC action.
• Garmin kicks off its biggest annual spring sale — deepest-ever discount on Fenix 8 Pro — while Apple's watchOS 27 (announced at WWDC) brings cycling power zone APIs and untethered Workout Buddy to the Apple Watch ecosystem — Monitor — if you've been waiting to buy a Fenix 8 Pro or Edge 1050, this is the window; for Apple Watch cyclists, wait for watchOS 27 public beta in July before committing to new workflows.
• TrainingPeaks-adjacent editorial debate: FTP vs. Critical Power — are coaches and platforms measuring the same physiological ceiling? — Monitor — no platform change to act on today; but if your training zones have felt off, ask your coach whether a CP test protocol would give you more accurate data than your current FTP estimate.

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

• Wahoo KICKR v6 firmware 5.6.13 introduced random power/connection drops in Zwift — no official fix yet — Hold on updating to 5.6.13 if you can; if already updated, file a Wahoo support ticket and monitor both the Wahoo and Zwift forums for a hotfix before your next important ride or race.
• CPSC issues stop-use warning for CARBO folding e-bikes Model X and Model S — manufacturer has refused to offer a remedy — If you own a CARBO Model X or Model S, stop riding it immediately; there is currently no manufacturer-provided repair or refund path, so contact the CPSC directly to report your unit.
• Strava paywalls its developer API at $11.99/month, citing AI scrapers — open-source ecosystem rattled ahead of IPO — If you use a third-party Strava analysis tool, check whether it still works and whether its developer has committed to paying the new fee; mainstream wearable sync is unaffected.
• JetBlack Victory gains wired USB-C connection to Zwift with firmware 4.28 — first trainer on the market to do so — Victory owners on Windows or macOS who have wireless drop issues should update to firmware 4.28 and give USB-C a try; for everyone else, wireless still works fine.
• Garmin Connect 5.26 APK teardown surfaces 'Enduro_4' device entry — no spec details or launch date confirmed — Monitor Garmin's outdoor announcement cadence around August 2026 before buying an Enduro 3 or a competing ultramarathon watch; no action needed now.

The pros are reportedly fuelling with 120 grams of carbohydrate an hour. A new Sports Medicine paper, "Fuelled or Fooled?", asks whether the evidence supports it. For most riders, the short answer is no. We break down what the research actually shows, why anything past 90 grams an hour mostly just sits in your gut, and what to do with your own fuelling.
