Welcome to our site! Here we have a plenty of road bike crankset axle length for you as your basic idea in your next Action! Feel free to download the image and use it as your guideline.

Road bike crankset axle length. Is the new crankset intended for mtb or road bike new mtb cranks are intended to work with 135mm old new road cranks with 130mm old. The shimano tourney a070 crankset is compatible with 3x7 and 3x8 drivetrains and provides wide range 50 39 34t gearing with a chain guard. Mountain version designed to work in frames shell width from 73mm to 92mm. This makes the bottom bracket shell asymmetric.
It has a 30mm diameter axle with pressfit bearings like bb30 but pushes the non driveside bearing out by 11mm for a bottom bracket width of 71mm. 68mm 5mm of spacer on the drive side and 2 5mm on the non drive. The average is 172 5mm but 170 and 175mm cranks are relatively common on complete smaller and larger bikes respectively and you can get as short as 160mm or as long as 180mm. Road version designed to work in frames shell width from 68mm to 86 5mm.
Thus if you know the chainline is 48 5 mm with a 113 mm isis drive spindle length then you automatically know that if you use a 118 mm isis drive spindle length your chainline will increase by 2 5 mm each crank moves outward 2 5 mm for a total of 5 mm. Once upon a time almost all bikes had 120mm old which grew to 126mm then 130mm. Cranks the arms come in different lengths to match different length legs and leverage preferences. Most cranks for road and mtb use are 175mm long but riders with legs shorter or longer than the average may feel more comfortable on cranks that better match their measurements.
As for crank axles shimano s 24mm axle gxp and 30mm axles predominate the current market however sram s new dub design see sidebar has added a 29mm axle to this short list of options. And mtb cranks with 36 middle and 44 outer could work. If you are replacing the cranks on your bicycle you may select a size based on your height and the size of your bicycle frame. A key consideration when upgrading or replacing crank arms or cranksets is crank length.
Using road cranks with mtb cups will do as you said run out of axle. Design bb axle length of your new crankset.
