Park ToolBBT-18 Chainring Lockring and Bottom Bracket Tool

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.

Süper

presa per smontare la corona del Brose , l'ho usata due volte e, come mi aspettavo da Park tool , ha svolto il suo lavoro egregiamente

Muy buena relación calidad precio, la llave de vaso a utilizar es de 8 caras de 36 mms, tuve q comprar una llave de vaso de 11 caras y encaja perfecto.

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.
