Size: Speed (Ball Bearing)
I recently put up a 90 foot zip line for my son. I used 1/4" galvanized cable. I started with the Petzi Tandem trolly even though it does state "for rope only" and now I know why. The steel cable quickly wears out the aluminum wheels, grinding a trough in them and slowing it down. I next purchased the Petzi SPEED trolly (saving a few bucks on the Tandem was a mistake and cost me more in the end). The SPEED has steel wheels and bearings instead of bushings. The wheels show no sign of wear and it is MUCH faster than the Tandem so you must adjust the angle of the zip line to slow it down. A word of caution, there is a label on the SPEED warning that you must have a way to STOP so you don't hit the tree at the end! Heed the warning! I used a zip line BRAKE BLOCK placed several feet from the end tree to prevent hitting the tree. So if you want to zip on CABLE get the SPEED but make sure you have a way to slow down and stop!

This is a great pulley for our backyard zip line. It is smooth, durable, good-looking, and easy to remove from the line. Shipping was reasonably priced, but it took a little longer to get to Canada than I expected. Overall, it is a great product and I believe it will work well for many, many years to come.

After trying two other pulleys on a steel rope zipline, I bought the Petzl Tandem Speed and found zipping happiness. This unit is incredibly well built (as with most Petzl gear), strong and durable. The "speed" model (this one) has roller bearings in its sheaves, which make it glide so effortlessly that I accidentally sent my daughter into the tree at the end of the first trial run. The hangtag warns against this, but I couldn't believe how little friction the device actually has. Since then I've adjusted the end heights and the zip line has a nice ride out, then glides back. Happy kids, happy dad. As others have mentioned, this unit is surprisingly small - like about the size of a pack of cigarettes. This doesn't seem to matter, although I was sure that larger sheaves would be faster. Apparently not. This unit is also very easy to clip on/off of a wire and is then secured from below. It could be padlocked onto a zipline and left, but I unclip it when we are done to prevent theft and unauthorized use from the insane neighborhood kids. Overall, a great product and worth the higher price.

great pulley does everything that is stated. Really fast and light weight. we used it on a 500 ft zip line at my moms on the 4th of july and it worked extremely well. Only problem we had was trying to keep up with the kids wanting to go down it. Awesome pulley.

We decided on the Petzl Tandem Speed Trolley for a couple of reasons. First, this trolley is highly rated in every review I found. It is well built and the metal wheels and bearings it should last a long time. Secondly and maybe more importantly, I especially like the ability to remove it from the zipline cable when not using, this should not only make it last longer, but it also prevents anyone from using the zipline when we don't want them to, I.e. When we are not home, etc. The only reason I didn't give 5 stars is the cost. It seems slightly expensive for what it is, but I would certainly buy it again. It is a fast little trolley and you can attach multiple carabiners if needed. We use a handlebar and a lifting strap attached to a Petzl Simba kids full body harness and are extremely pleased with the setup.

Just what you expect. Solid build, easy to use with a carabiner, and much faster than a cheap pulley. The only thing I don't know is how well it will hold up with my rough, small-diameter steel cable. Seems to be doing well so far, but I haven't had it long enough to tell. Actually, it went so fast I crashed into rocks on the other side of my 200 foot zipline, something I wasn't expecting at all given past 10 dollar pulleys. :)

Grandkid and neighbors or going to love this pulley. It flies! Excellent choice for those who want to create a fast/safe zipline. When I was a kid, my father installed what he called a "shoot the shoot" in our backyard. It was a neighborhood meeting place for years. The first thing he did when my wife and I moved into our house was bring over a cable and pulley and installed it in our backyard for his grandbaby that was not yet born. Again, we were the meeting place for neighborhood kids a an instant hit a birthday parties.

I found this lifesaver while reading reviews of the cheap $30 Chineseum brand knockoff and I'm so glad I got this one. I set it up on a 100' 3/8" cable and it held up great. I tested on a 1/2" cable too, and it fits. This trolly is a little bigger than a deck of cards, lightweight and built strong.
