This looks a handy little gadget for tensioning bike chains - not sure it will hav enough adjustment for a TDM though

goes up to 70 mm slack so it should work ok on a niner

Looks like a complicated way to achieve a simple task.

Not got audio at work so it may have been mentioned, however I notice he measured the chain thickness and then looked up a setting, did it take in to account the length between the sprockets?

Nope...

You just measure the link size, and then based on that & the slack required you set to one of the pre-defined Chain Monkey settings.

Once it's attached to the chain (creating the arc shown in the video) you adjust the chain to no-slack.

Then when you remove the Chain Monkey the correct amount of slack is created...

 

Nice idea, and removes the what position should the bike be in to achieve the Yam stipulated slack, but quite a price for the privilege.

Has anybody tried one yet? If so please give a review.

[TYREDNGRUMPEE]

I recall that over 18,000 miles of TDM ownership, that I have only had to adjust the fitted chains slack 6/7 times and that was due to me fitting non-standard sprockets, new tyre and brake pads at different intervals.

 

Did it again this weekend (lubing suspension) and discovered n'ary a tightspot after what must be over 20K in total.

 

Anyway. Isn't that what the underside of the black plastic chain guide is for anyway? "Chain Python" ™

[celticbiker]

Really TD?

I only adjust the chain four times in 30000 miles.

Adjusted mine 3 times in 22k, once too tight, slackened off to correct adjustment then again 15k later. I just use a ruler.

I had a friend do mine once a couple of years ago for me, at about 12,000 (don't know how often it was done before). But if I'd known I only needed a ruler I'd have done it myself.

I think we must all have tools that are rarely used but ideal when required. For example how often do you use a "puller"? But when needed is a must have. I think I have used mine once.

[celticbiker]

Same here, got a torque wrench and a set of vacuum gauges that have never been used.

The difficulty comes when you need it but it's been so long since you put it away that you can't remember where you put it and have to buy another one.

(I am of course talking about myself, and have today bought another magnet on a wire stick thingy. I dropped a fuse and 'lost it' the other week. This may even be the 3rd one I've bought over the last 5 years, only used each one once).

Same here I've got 2 of quite a few things....

I suppose thats why so many on here seem to own two or more TDMs, after the winter lay off it must be difficult for them to remember where they've left the bike!

[Catteeclan]

I normally buy a "special tool" as and when I need unless I can get round it. So yes I have a few that'll only get used once or twice.

[NickIAM]

I bought a voltmeter current testing thingy the others week... Should have stuck to my screwdriver with the bulb in it.

[leehenty]

I have quite a few tools that sometimes never get used, unless it's once of those special jobs.

Large sized fine pitch helicoils is one example, but the Pan Clan had need last week and I was able to help.

I have quite a few pullers, pushers and pinchers that get used for TDM fettling, plus all the fork tools as it makes the job so much easier.

I'm a gear freak anyway so you can never have too many tools.

The chain monkey is too expensive for what it does, when a simple 150mm ruler will do.

You can get laser wheel alignment tools as well but a bit of straight wood will do the job just as good.

 

I have a digital torque gauge that has a lot of range. Fancy bit of kit but lets you torque left hand threads with ease.

Just used my Chain Monkey for the first time.
Makes fitting and adjusting the chain a doddle and also very accurate.
It has been said on this thread it is a little expensive but it does what it says on the tin.
