Weather changes everything
A wet, gritty ride is far harder on a drivetrain than the same distance in the dry. Grit turns a chain into a grinding paste. Most trackers count both rides identically.
Clym · for iPhone & Apple Watch
The bike computer that knows your bike.
It records the ride, tracks what the ride cost your bike, tunes your suspension over a live ShockWiz link, reads your e-bike's own telemetry, and answers questions about your riding with built-in AI.

Trails · routes · your best self
Find it. Plan it. Race yourself.
Discovery to redemption in one loop: find the trail, build the route, ride it with turn cues on the bars — and then ride it again, against the only rider worth beating.
- Trail discovery with receipts. Search trail systems near you or by name. Clym researches the official sources live — hours, fees, e-bike rules, terrain — every fact cited, unknowns admitted.
- Routes your way. Draw one, import GPX, or record a course by riding it. Turn cues are built from the line itself and spoken on the bars.
- Guidance that owns its limits. Off-route alerts that escalate with real options, voice rerouting, a breadcrumb back to the start, and an ETA that declines to guess when you're stopped.
- Race your own line. Repeat a route and ride against your best run live. Afterwards, saved segments split into zones: where the time went, your make-or-break zone across every pass, and one coached move — measured, never judged.
The gap
Your bike doesn't wear out by the kilometre.
A service interval printed on a box assumes an average rider on an average day. But two riders can log the same distance and finish in completely different condition — and so can their drivetrains.
So does terrain and torque
Loose surfaces, sustained climbing and high torque all load components differently. A steady road hour and a technical gravel hour are not the same hour.
And so does the bike itself
E-bikes put more sustained torque through the same chain. Heavier loads, wider tyres and rear-wheel bias all shift where the wear lands.
None of that is exotic — any good mechanic will tell you the same thing. The hard part is noticing it consistently, ride after ride, across a season. That's the part software is genuinely good at.
Why Clym is different
Not another bike computer app.
Every cycling app lives in one lane: tracking, or navigation, or maintenance, or one vendor's hardware. Clym is one data model across all of them — and that changes what's possible.
Wear by conditions, not the odometer
Maintenance apps count imported miles. Clym records the ride itself — weather, terrain, torque — and weights every kilometre by what it actually cost. A photo can even recalibrate the model.
The trail, measured at the bars
The phone's motion sensors classify every second of surface — smooth, chatter, rough, severe — speed-normalized, with a braking ledger. Your rides build a terrain memory no map has.
ShockWiz, beyond SRAM's own app
Clym speaks the sensor's Bluetooth protocol directly: a 0–100 tune score, one clear move, a Funometer, and a logbook that coaches your next setup.
Your e-bike, in watt-hours
Clym reads the Specialized Turbo Levo directly: energy in watt-hours, not just a percent, with rider power and motor power kept honestly separate.
AI that closes loops
Not a chatbot bolted on: the ride's story writes itself when you stop, the morning brief arrives unasked, a spoken answer meets you mid-trail — every claim grounded in your measurements, and it says so when it can't know.
Recording that survives anything
Every second is committed to durable storage as it happens. Recovery is tested by killing the app mid-ride, on purpose. Zero rides lost.
Honesty as architecture
Estimated is labelled estimated. Unknown is never treated as fine. Advice is computed before anything commercial touches it. These are code paths, not values-page copy.
What Clym does
Three jobs, done properly.
Ride
Records the ride
GPS, elevation, speed, power, heart rate and cadence from standard Bluetooth sensors — written down continuously so a dead battery or a crash never costs you the ride.
Garage
Understands the wear
Every ride is credited against the components it actually used, weighted by the conditions you rode in. Your garage stays current without you logging anything.
Service
Tells you in time
You hear about a component before it becomes expensive — with the reason, not just a percentage. And if you want, your shop hears about it too.
Suspension tuning
Plug in a ShockWiz. Get one clear move.
Clym connects directly to SRAM's ShockWiz over Bluetooth and turns a ride into a tune: a 0–100 score for the fork or shock you're working on, a live travel histogram, and the single change to make before the next run.
- Detection engine. Bottoming, packing, pogo, bobbing — found in your travel data with a confidence score, not a guess.
- Guided calibration. Pick the end, verify full range, set sag against the right target — in three steps.
- The Funometer. Jumps, airtime, and a Gnar score, because tuning should make riding more fun, not just more correct.
- Stays connected. Battery voltage, signal strength, and automatic reconnect when you ride back into range.

E-bike intelligence
Your Turbo Levo, in watt-hours.
Clym connects straight to the Specialized Turbo Levo and reads its own telemetry — so the number that matters is energy, in watt-hours, not a five-bar guess. Rider power and motor power stay separate, because pretending the motor is your legs helps no one.
- Energy, honestly. Remaining watt-hours alongside percent, battery temperature, motor temperature, and the odometer — the bike's real state, not an estimate.
- Rider vs motor. Two separate power channels. Clym never merges the motor's watts into yours, so your effort stays your effort.
- Reads, never writes. Clym listens to the bike; it never changes a setting, touches the speed limit, or does anything you can't undo. Your Levo is yours.
- Range that learns. Energy plus route, elevation, and your recent assist mix — an honest range band, not a promise, that sharpens every ride.
Clym AI
Your data · your garage · the sport
What should I ride today?
Measured: your last 3 rides averaged 11.2 mi with load trending up 14%. Sleep was short Tuesday (5h 40m). Interpretation: keep today aerobic — your legs earned an easy trail spin, and your fork service is 62% along, so it's fine to ride.
Ask Clym AI…
Clym AI
Ask anything about your riding.
Clym AI reads the same workspace you do — your rides, health context, weekly goals, and every component in your garage — and answers in plain language, streaming word by word. Ask why a ride felt hard, what service is coming up, or how to corner better on loose rock.
- Grounded in your data. Claims about you come from your measurements; when it can't know, it says so.
- Knows the sport too. Technique, gear, suspension theory, training principles — and it tells you which answers are general knowledge.
- Private by design. Only the aggregates already on your screen are sent. Raw health samples never leave the phone.
AI in the loop
It notices before you ask.
Chat is the least of it. Clym's AI closes loops on its own: the moment a ride ends its story writes itself, each morning the Ride screen briefs you on conditions, bike, and legs — and a photo of a part can argue with the wear model and win.

Big day at Sedona: 12.4 mi with 1,900 ft of descent across 5 runs — your fastest top-to-bottom yet. The fork took the hits but packed late in run three; the chain picked up 2.1 wet-weighted hours and your brake pads crossed 60%. Legs carried it well after two rest days.

A morning brief
Weather along your routes, the garage's wear headline, and what your legs earned — three sentences, written fresh each day, before you've asked anything.
Voice on the trail
“Log: rear tire felt vague” pins a crash-safe note to the ride — and the Debrief quotes it back. Unrecognized questions get a spoken answer from Clym AI, two sentences, hands on the bars.
Every number answers
Tap a wear percentage, a tune score, or your form curve and Clym AI opens with the question already asked and the exact figures attached.
