Releasing this Friday to Profile retailers are the new Fixed 3/8 Axles. As you can see, the Profile Fixed 3/8 Axles are solid, and features a oversized aluminum center female style axle with a choice of Titanium or CrMo axle bolts. Inspiration came from Profile’s best selling BMX Mini hub, and is said by Profile that these axles are virtually indestructible. Lastly, the cone spacers are manufactured out of aluminum, using a steel washer to grip the frame.
