Extralite Black-Lock 12x148mm Boost Rear Thru-Axle
Extremely light thru-axles for 12mm thru axle Boost frames. Their unique design ensures a prefect function with a well balanced dimensioning.
The notched area of the thread get reinforced by the allen groove and locking/tightening forces do not affect the axle with useless torsional stress.
Machined with our usual Extra-care, makes you save up to 50g! The bronze washer adds a smooth action, a tricky nice touch.
