Street Cuffs

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Anyone have any opinion on whether to use the 9-link version or the shorter version?

The 9-links seem a bit easier to use, just because they have longer reach.

Elsewhere I have heard it opined that the 9-links are essentially defective, because used a certain way it is possible to tilt the link chain "sideways" and use the bike as leverage to break the chain out of the base of one of the cuffs. As long as you lock both cuffs around the bike and run the chain around whatever stationary object you have, that won't ever be a problem.

Also we note that although the Street Cuffs appear to use a regular round key, they are not susceptible to the bic pen trick. I have heard people online claim this but have yet to see it demonstrated.

If you have a pair of Street Cuffs to study you will see that there is a significant difference in how they function. With the old Krptonite locks, the center post rotated and that was how the lock was opened--the bic pen had to fit tight on the center post, so you could turn it. With the lock that the Street Cuffs use, the center post does not rotate at all, and the lock is not opened this way.
