Review: Perfect size and quality - Works for what I need.. my Yakima bike rack has a built-in locking mechanism for the actual receiver portion but an extra layer of protection is always nice for peace of mind. I run this decent-size cable through the Yakima carrier directly to the hitch itself and lock it with a medium sized American Lock. I'm sure bottom line if somebody wanted it bad enough they'll go through the trouble of cutting it, well know that scum of the earth is in every state. but for 10 bucks I feel like it's definitely worth it and I love the quality feel of it
Review: Good cable - long enough to lock up components. - On a 60cm bike with a very high seatpost this is long enough to lock up my saddle, rear wheel, and Vector pedal (left side only). I lock my bike with an Abus Bordo X-Plus (like a U lock but the U is in flexible segments instead of a rigid U). I put the lock around the front wheel and frame, and this short cable is enough to add a little deterrent to the bike components. I don't have any theft protection on the cockpit beyond the brake and shifter cables. As it stands, someone would have to use tools to take most things off my bike - they could get the skewers - nothing else comes to mind... I can fit this cable in my back jeans pocket, but also I am 6'4" so IDK whether that would be true for smaller people. I wear 34" waist jeans. I'm still searching for a way to easily/quickly carry this on the bike but so far IDK. Also fits in a jersey pocket. The velcro cable tie is a nice touch - keeps it from springing open when coiled in a pocket. I wish it was smaller. I wish there was no theft in the world. BTW I'm sure most people know this already, but just in case this is the only text you ever read on locking up a bike: the trick to getting the most out of a double-loop cable is feeding it through one of its own loops. One end is looped around a wheel or saddle rail or whatever, and the other loop goes through the lock. That way you get double the coverage - or half the cable length - as you would putting your main lock through both loops of the cable. HTH, Michael

## Questions & Answers

**Q: How does this secure your seat from theft?**
A: It will secure your seat. Slide one end of the cable through the metal frame under your seat. Take the other end of your cable and put it through the loop that you slid through your frame. It makes like a noose. With 6' of cable, plenty of length to reach the front wheel of your bike for further locking. I do this on both of my bikes.

**Q: I would like to use the krypto u-lock ny for the back wheel, along with a 5' chain to lock up front and post.  will the chain links fit the u-lock?**
A: It should fit a standard padlock if that is the same as a U lock

**Q: Will 8mm padlock fit cable end? What size is the opening for a lock attachment**
A: The steel cable is thick, it measures 1.5 inches around. So you may want to test the lock to see if there is enough clearance.

**Q: Is this cable long enough to fit through both wheels and be attached to a U-lock?**
A: This is a 4' cable. You may want take a measurement of your wheel base to make sure it going to fit your needs.

### ⭐⭐⭐⭐⭐ High quality and strong cable!
*by B***H on June 9, 2013*

Even though I would never rely on this cable or any cable lock as my primary lock, I feel confident using this cable to lock my seat if I am using 2 high security locks. If I am gonna be real quick and pretty much have my eye on bike, I could use 1 high security lock and put the cable from my lock through my seat to the front tire. This cable is nice and thick and it is braided which is stronger than the twisted coil cables that most riders use.
