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

• Karoo Build 1.640.2470 brings color-coded trail difficulty maps to all Karoo devices — Update now — Trail Maps is a genuine feature unlock for any gravel or MTB rider, and the Target Power fix is a quiet but real win for structured-workout users.
• Oura Ring 5: world's smallest smart ring launches at $399 — excellent for sleep and recovery, weak for cycling sports tracking — Early multi-source impressions are broadly consistent on the hardware quality but uniform on the sports-tracking limitations — monitor for further software improvements before treating it as an athlete-grade device; if recovery tracking is your primary need and you dislike wrist wearables, it warrants a closer look.
