Sturmey Archer X-FD Front Drum Hub Brake Arm Clip - UNSAFE
Hello - I'm sharing a bad experience with about the Sturmey-Archer X-FD Front Drum Hub
Brake Arm Clip I just had. I'm talking specifically about the clip and the way S-A has decided one should connect the front brake arm to the fork.
The Sturmey Archer X-FD Front Drum Hub itself is beautiful and well-engineered and manufactured.
I have the X-FD hub installed on my 26" cruiser BMX style bike. The clip which holds the brake arm to the fork completely
failed the other day while I was braking, fortunately, I was going relatively slow and was not hurt.
The hub with the attached brake cable broke loose and proceeded to wrap itself around the axle/hub ripping the brake lever loose
from the handlebar and snapping the brake lever in the process. If I had been going any faster, I would have done
a front flip as the front wheel would have locked up with the tangled brake cable wrapping around the hub.
The design of the Sturmey-Archer Brake arm clip is a poor and insufficient design. I do not understand why Sturmey-Archer
has not drilled a hole in the brake arm and used a bolt and bracket to secure the arm to the fork. Am I missing something? There also is very insufficient
grip/coverage area from the bracket to the arm to hold it securely in place. The metal for the bracket is cheap and thin. My brake arm bracket snapped from what I assume is
metal fatigue. I've only had the hub installed for about a month!
Do yourself a favor if you install this brake on your bike. Don't use the provided Sturmey-Archer front brake arm clip (S-A Part #: HSL 702 or 703). Use something a bit more robust. I'm going to use
a worm gear interlocked hose clamp with some rubber gasket underneath it to protect the fork and keep it from slipping. I might drill a hole in the brake arm and use a screw and bracket
to secure it to the fork.
