Sprint GT Drive Chain Adjustment

If you have a Seized link that will not free
New chain and I wouldnt want to ride it.
Set the chain, on centre stand, measure on side stand.I think thats right.

 

And dont even join the chain.See if you can borrow one.
All chains have a tight spot.

 

whatever chain you buy use a good quality tool to rivet chain together,wemoto etc sell decent chain tools at good prices unless you can borrow one as how often will you use tool.

 

I've just bought one of these https://www.ebay.co.uk/itm/382452402887?clk_rvr_id=1527187917232&rmvSB=true
It comes highly recommended by a chap who really knows his stuff and it's cheap. Use an angle grinder to break the old chain.

This works

 

ive used angle grinder few times just need to be careful but works well,replaced chain on my old zrx 3 times because swinger is braced and put a nice jmc job on bike.

 

Probably both made in China?

 

The guy who recommended the one that I've just bought has been using his for 8 or 9 years. He's a right stickler for tool quality so I had no hesitation in buying. If it turns out to be crap then it's only £12 down the drain but I'm sure it'll be fine. And you get a selection of different sized pins.

 

Agree, that's what I meant, buy cheap as they are all made in China.
Unless you are in the trade how often are you going to use it!

 

Couple of things.
Don't over tighten the chain. It needs a good 40mm of slack. Sit on it and see how tight it gets!
Also on a ST the caliper carrier was anodized. No problem, but the GT is painted and bare ally where it fits on the eccentrc. This corrodes and seizes the eccentric in place so you cannot adjust the chain. Remove it and make the hole slightly bigger (With a file is fine) and fit with plenty of grease. This will help a bit.

 

I was given one of these from a mate who was giving up biking. I've used it 3 times now and it worked perfick every time.

 

Can I add -; the chain has tighter and slacker points, all the way around, with the ruler in place, find the slack point, on the side stand, measure the slack, on the centre stand adjust the slack, then side stand and check. In neutral
26mm to 38mm . Bottom middle.

 

Always measure at the tightest spot. If the difference is excessive then time for a new chain and sprockets.

 

Clean it in place, or buy a new link, honestly just clean it in place, if its just clean, and not repair.

 

I had the same problem last year.I ended up getting my money back and buying an Oxford one.

 

For the record, It's been over twenty years since I maintained a chain...how would one lube a chain and how long {miles) does a chain generally last with regular riding....no racing?

 

Should last 20,000 without touching it, and no lube. Regular adjustment, cleaning and lube 4 or possibly 5 times as long !
