Tru-Tension | Chain Monkey | Motorcycle Precise Chain Tensioning Tool

easy to use, works excellent, reconended

They should provide better examples of the chain tension setting. Ducati asks you to measure the gap between the center link of the chain and the swingarm surface. Does this correlate to the measurements provided on the back of the product card? To answer this question, I went to my bike which had the chain tensioned in accordance with the factory service manual, and proceeded to crank down on the Chain Monkey. I found that it came close, I had to really crank down on the Chain Monkey to match the setting. So I feel the Chain Monkey may get me there, but more consistently each time. The crank knob kept coming apart, the end cap kept popping out. Overall: 5/5 stars

Not precise but close enough. Don't tighten the chain too tight with this attracted. While it is robust, you can crack it if you apply too much pressure. One thing that really bothered me was having to measure the chain cross section. Come on. A 520 chain is a 520 chain. A 630 chain is a 630 chain. Since this isn't a precise measurement anyway, why not just give me a setting for a 520, 530, or the 630? Other than that little twerk, it works as advertised.

Easy to setup and use.

I really wanted the Chain Monkey to work. The concept seems sound, however the implementation is not. On my chain and on the first try, the tool's domed nut was getting ground down by the chain, and I found metal shavings from the nut on the chain. I could feel the nut grinding away, so I backed it off before I even achieved minimum tension. Upon removal, I found a deep circular scar on the nut. Would this mean it would require regular recalibration to account for the lost material? Possibly. In any case, I'm not thrilled about the idea of leaving metal shavings on my chain and wearing down the tool with every use. It really needs a redesign to allow the nut to swivel on the screw so that the nut isn't rotating against the chain.

Definitely need to watch some YouTube videos to know what your doing and play with it but once you get the hang of it. Pretty simple

I wrote a review for the LED product and how it didn't fit. However, this works. Just follow the instructions for proper chain tension. I used this product to calibrate the other chain tension product (BP Racing I think).

This simple tool supplies an easy way to check chain tension and it also is a big help when adjusting the chain. It is easy to use, and once you set it up so that it accurately tensions the chain, it is a no brainer to use. I wish I had thought of it.

un ajuste rápido y preciso de verdad es excelente.

Very easy to use

Perfecto.

Easy to use

Wish I’d known about this years ago! Used to use a tape measure and eyeball never really precise. Good quality easy to use.
