How much does it cost to maintain a bicycle
Expenses for the year, month and kilometer: parts, consumables and mechanic's work. Its prices and resource, saving to the bike in the garage.
CALCULATORS
Go to the main pageBicycle expenses, tire pressure, gears, power, landing and frame geometry are applied tools for our races and rides.
The tool
Tire Pressure Calculator
Starting pressure recommendation based on system weight, tire width, temperature, coating and average speed.
The tool
Transfer Calculator
Fix and singlespeed: gear ratio, skid patch, development, gear inches, gain ratio, cadence/speed and equivalents ± 2%.
The tool
Transmission range
All 1x and 2x transfers: development, gear inches, steps between the stars, 2x takes and checking "if you're going to get up."
The tool
Meals for the race
Carbohydrates, liquid, sodium and caffeine for duration, pace and heat — with pocket layout and timeline.
The tool
Landing Calculator
The position of the steering wheel and saddle from the carriage, the drop, the STR and the selection of the take-out with spacers when moving to another frame.
The tool
Comparison of frame geometry
Two or three frames side by side: stack, reach, corners, base, trail and human output, how they differ on the go.
New
Watts and speed
How many watts do you need for speed, taking into account the slope, wind and altitude — and which is faster: to lose a kilo or to sit lower.
New
Zones and FTP
FTP from the test, Koggan power zones, Friel and Karvonen pulse zones, polarized triple and W/kg targets.
New
Chain: length and wear
How many links do you need for your feathers and stars, when to change the chain according to the ruler and how much is left for it.
New
Wheel and tire
The length of the spokes on the ERD and bushing, a pair of rim-tire, clearance for dirt and how much sealant to pour.
The tool
Compare watts
Comparison of two FIT-files by power, pulse and cadence with a graph and statistics on segments.
