Whether quick release (also quick-release skewer) or thru axle on the MTB, both enable a simple installation and/or disassembling of the bike's wheel.
For new high-quality, modern mountain bikes, practically only thru-axles are used. The quick release is almost history or wickedly spoken, it is something for the retro faction. Thru axles are included in the delivery scope of modern frames and forks, but be careful, there are big differences:
Whoever thinks that the thru axles are still too heavy, has the option to improve: Tune e.g. offers especially light axles which can even be ordered in the matching colour, in order to provide the final touches and also an individual look.
Salsa, Sixpack, Specialized, DT Swiss, light and coloured from Hope, Tune or Extralite (and many more)... our selection of thru-axles and MTB QRs is large and we offer something for every purse.
By the way: Among our quick releases, you'll also find "anti-theft devices" for the wheels, they will then replace the standard quick-release levers. Ideal for city, trainings and all-purpose bikes.
