It's Simon Jamison in Surrey Hills... Several members here go to him and recommend him.
I'm a bit like Toolonglegs - I have broken 3 frames, 3 cranks, 2 handlebars, carbon forks, stems, seatposts, saddles, pedal axles, rims and countless spokes in 25 years of cycling so chains are hardly a surprise!
The only surprise is that it was at the joining link and the 9 speed and 11 speed happened within a few weeks of each other,
Andrew

Nothing special, I just use a Park chain tool to push the pin so it's only in one outside link and then break the chain. Reverse the process to rejoin.Nobody wrote:So what special thing do you do to the regular pins and what do you weigh?panurge wrote:Notwithstanding all the good advice on this thread I will say that I've split andrejoined probably 100+ Shimano chains over the last 20 years using one of the regular pins and I've never had one fail on me.
I weighed about 65kg at the start of the 20 years and about 72kg by the end. I blame living in Belgium for 8 years in the middle.

I think everyone did before 10 & 11 speed chains. I have joined 10 speeds the same way in an emergency and not had an issue... which is how I remember I have broken one road bike chain, descending the Koopenberg last year ( obviously wasn't peddling! ).panurge wrote:Notwithstanding all the good advice on this thread I will say that I've split andrejoined probably 100+ Shimano chains over the last 20 years using one of the regular pins and I've never had one fail on me.jules21 wrote:has anyone else tried to connect a chain with pins previously pushed out of the chain to shorten it?

Previously I always rejoined chains using the original pins and secured the pin by giving the centre of the pin a gentle tap with a centre punch and hammer, expanding the end of the pin ever so slightly.
My favourite chain tool used to consist of a lump of steel with a 1/4” hole drilled in it that allowed me to tap a pin out with a small nail punch.

My park tool has a collection of little metal rings on the pin which I have assumed come off the link pin when it's pushed out. There's no way I would be reusing those pins! Besides which, Shimano always gives you two with a chain, I have any number of spares kicking around.panurge wrote:Nothing special, I just use a Park chain tool to push the pin so it's only in one outside link and then break the chain.

Only got one from my PBK order as well. If anyone has a spare shimano 10 speed link joiner thinghamy I'd be happy to paypal you a small sum of $$$ for it and postage. Seems as though most online shops don't want to sell these on their own. Just PM me.

Not sure what OEM is, but they were "7,8,9 Speed" narrow chains, all new in box (with instructions). One pin each. Not to worry though, like I said, I've yet to have one of my recycled ones break.twizzle wrote:OEM chains rather than retail packs in a box with instructions?

It's possible, though the chains were in Shimano boxes, with Shimano branding on the instructions. The pin came with each chain had a "guide" part that snapped off once the chain was joined.

6 to 9 speed shimano chains come with 1 pintwizzle wrote:Sounds like retail packs to me. Has Shimano gone stingy recently? I've always gotten two in the past!
105 & Ultegra come with 1 pin
XTR & Dura Ace come with 2 pins

YMMV, but a mate is waiting to get his frame back from being repaired after a rejoined chain using a new pin came apart in a sprint, ripped the derailleur off, trashed the carbon wheel and broke off part of the hanger mount on the frame. A $4.5K TT frame. Pushing a pin out doesn't do much for the side plates.
I also never remove chains until they are being replaced.

Good example of why to use a quick link if at all possible.twizzle wrote:YMMV, but a mate is waiting to get his frame back from being repaired after a rejoined chain using a new pin came apart in a sprint, ripped the derailleur off, trashed the carbon wheel and broke off part of the hanger mount on the frame.
