Build Notes 01: a bike name becomes a factory-build candidate and a parts list to review. Real Quiver app footage. Check the year, trim, and fitted parts before saving. iPhone + Android. Follow for the next Build Note.
The bike's gone from the truck. Insurer wants a serial, a parts list, what each piece cost. Scrolling two years of email at 11pm trying to remember if those XT rotors came stock or you bought them. The worst time to build a record is after the theft.
Reach 478, stack 635. Reach 465, stack 628. Three tabs open and you still can't picture which bike feels roomier. Geometry charts give you numbers, not meaning. Two frames should compare on how they actually feel, not just on a spreadsheet row.
Most spec tools state every number as fact. Fork travel, cassette range, damper tune, all presented with equal confidence even when half is a guess. A confidently wrong spec sends you to the shop for the wrong seal kit or undersells a bike at resale.
The XT rotors you pulled off the trail bike are now on the gravel rig. What did you pay for them? Which bike wore them first? Parts move between builds constantly. A record that forgets cost and provenance the second a component changes frames is a snapshot, not a history.
Your Rivendell doesn't fit in a road bucket or a commuter bucket and it shouldn't have to. Steel touring rigs, bikepacking oddballs, all-road builds from Surly, Crust, Fairlight. The bikes that refuse a tidy category usually break these apps because nobody made a place for them.
Swapping a GX cassette for an XT tells you the weight. The number that matters is the delta: grams and dollars you moved off the factory build. Stock vs upgrade means nothing if you don't know what came on the bike.
Reach and stack tell you how a bike actually feels, not just how it looks on a geometry chart. Two trail bikes with 150mm travel can ride nothing alike if the stack is 20mm apart and the reach shifts 15mm. That's the comparison that matters at the bars.
Serial number and purchase price are the two things you can't reconstruct after a theft. Write the serial down now, save every receipt, keep a running total of every dollar across your bikes. Hand the insurer the record, not your best guess at the worst possible time.
@AppsFlyer Your web signup flow is broken for me. MacOS Safari & Chrome. Can't get past the "Tell us about your role" step... Next button clicks but doesn't progress me in the flow.
New bike day protocol before the first ride: find the serial number and photograph it. Usually under the BB or on the rear dropout. You won't remember where it lives when the bike gets lifted. #nbd#newbikeday
Every serious rider starts a bike spreadsheet, then abandons it. Re-typing the whole spec after one cassette swap is misery. Six months later you are second-guessing what is actually on the bike.
the swap delta nobody calculates: what did the upgrade actually buy you versus stock, in grams AND dollars. "feels lighter" is not a number. compare the new part against the factory build and you get the real answer to the question every rider asks after a swap: was it worth it.
your bike collection lives in four spreadsheets, a notes app, a folder of screenshots, and a memory you can't trust.
every part swap you swear you'll log later. half the time you don't.
the real cost isn't the typing. it's never trusting your own records again.
