Park Tool BBT-18 Chainring Lockring and Bottom Bracket Tool

I had to extract an ISIS bottom bracket for a Schwinn spin bike. I tried two other BB tools first - one from Lezyne, the other from Icetoolz. Both were very well made, but neither of them would fit the cutouts on the retaining ring on the spin bike. So, I had to send each one back, and wait another two or three days for the replacement to arrive. All to save a couple of bucks (or gain a little extra functionality) over the Park Tool.This is well made, and it fits the purpose for which it was designed. BE AWARE though, that you will either need a 36mm socket for this, or a very large crescent wrench. Oh, and that would be an OCTAGONAL socket - 12 points will work, but a HEX SOCKET WILL NOT. Hopefully that saves someone either heartache or money... or both. Yeahh... it cost me a couple of extra days (and more moola). It would be great if this had a 1/2 or 3/4 inch drive socket on the end as well as being cut for hex or 12 point so, but given that it's the only tool I've found which does the job, I'm not going to dock it a star.

Used to tighten Peloton. Worked great.

the BBT-18 fits a the chainring locking on a Bosch gen 4 motor perfectly. You however need a 36mm socket, wrench, or adjustable wrench to turn it, I used a 36mm socket so I could use a torque wrench.

Exactly what we needed to get the job done

I purchased this to tighten up the right bottom bracket nut that was loose. The product is made of durable metal. It didn't fit into the bottom bracket initially so I used a grinder to shave off a little on each side of the notches of the tool. One of the notches was also bent so I ground it to make it fit. After the adjustments, it fit perfectly in the bottom bracket of my peloton bike. Like many tools the item fits prior to having a powder coat of paint applied and then it doesn't fit due to the extra thickness from the paint. Remove some of the paint and then it fits perfectly.

Precision tool but you will need a 36mm socket for this and a 1/2 drive ratchet/torque wrench. I use this to remove the spider off of my 2023 Specialized Turbo Levo Carbon Gen 3.

I've used this tool several times, and I wish I'd had it years earlier.Because it is hollow, I can put a quick-release skewer (QR) thru it and the bottom bracket (BB) (with a fender washer on both ends), and it stays securely in place. Without the QR, it is almost impossible to hold the tool in place and impart sufficient torque to loosen the bottom bracket, without it slipping.I have a similar version of this tool, but that one is not hollow, and is almost useless, as it slips far too easily, marring up the soft aluminum BB cups/lockrings.So, if you don't have it - get it!

Everybody is taking about shaving or filing the prongs... Instead of doing that I lightly tapped it in place with a mallet. It was snug but it went on with a few taps and worked perfectly.

Not cheap, there are certainly alternatives.But, I like to buy Park Tool products when I can as they tend to be "tools for life" and this is certainly one of those, worked perfectly (along with an adequately sized spanner) for removing the castle nut on my turbo levo.
