Bergamont Grandurance 8 Axle: Keep Front, Rear and Wheel Interfaces Together
The Bergamont Grandurance 8 axle entries distinguish a 12×100 mm front interface from a 12×142 mm rear interface on the inspected model 291088. The hubs are listed as BGM Allroad with Centerlock disc interfaces. Preserve the wheel position and the complete description when asking for parts.
Bergamont Grandurance 8 axle: front is not rear
The fork entry also specifies a 12×100 mm axle. That agrees with the front hub description, while the rear hub has its own wider standard. Copying only “12 mm Grandurance axle” leaves out which end of the bicycle needs attention.
These hub-interface entries do not publish every dimension of a removable replacement axle. If the axle itself is missing or damaged, request the exact frame or fork part rather than interpreting the hub’s nominal width as the complete axle length.
A shared wheel-size label does not establish interchangeability
Bergamont’s inspected Sweep 4 EQ page describes BGM Pro quick-release hubs instead. Both bicycles appear in road-oriented, 28-inch listings, but their retention descriptions differ. A spare wheel cannot be approved by wheel diameter and brand alone.
For a complete wheel, add the actual brake-rotor and cassette requirements to the enquiry. The Centerlock entry describes the documented rotor interface; it does not identify every other hub component or make a wheel from another drivetrain an automatic match.
Bring a wheel inventory to the supplier
State whether the job concerns the front wheel, rear wheel, removable axle or a hub component. Include readable markings and a photograph of the actual dropout area. If the bicycle was bought used, describe any known wheel changes so the original specification and current assembly can be compared explicitly.
Have the supplier confirm the complete replacement and the applicable fitting instructions. This guide provides no guessed thread pitch, bolt length or torque for an unidentified axle. A part that initially enters a dropout has not thereby passed a compatibility check.
The historical rim-brake Prime Team Carbon pictured here demonstrates how broad the Bergamont name is. It is not the Grandurance disc-wheel assembly, and no hidden axle dimensions have been measured from its photograph.
After the correct component is confirmed and fitted, retain its exact reference with the bicycle’s documents. That record makes a later wheel service easier to describe than a general note saying “Bergamont through axle.”
FAQ
Which interface belongs at the rear in this specification?
The inspected model lists 12×142 mm at the rear.
Does 12×142 specify the whole removable axle?
No. It does not supply every replacement-axle dimension.
Can a Sweep quick-release wheel be assumed to fit?
No. The actual retention system and complete wheel requirements differ.
Resolve the Bergamont Grandurance 8 axle request by wheel position and exact component. The Bergamont introduction supplies family context, and the technical topic groups related ownership questions.
