Broken Chain

I don't know what chainset it was that you buggered, but perhaps Decathlon could have ordered a new crank arm rather than replace the whole chainset, in fact the LBS could have done this too, did they even suggest it, or just go straight to a full new chainset?

Either way I agree with SJ, there is just no reason to split a chain when fitting a new chainset. I'd take it into Decathlon and not mention the chainset. If they mention just tell them what happened and tell them the chain was not split to fit it. It's true chains are inexpensive, but as your already £60 down this month every little helps.

The Rockrider 5.0 (OP's bike) isn't the most expensive bike on the market - The chain rings are probably riveted together and non-removable from the crank.

Although saying that, it sounds like a more expensive chainset has been put on, where money could have been saved by installing a chainset equivalent to the original, such as one by SR Suntour.

Jeez, I hadn't even looked at what the bike was TBH. For an extra £40 the OP could have bought another bike and had a world of spares on stock

Unfortunately if it's the drive side of a Hollowtech style crank then you more or less limited to a new crankset afaik. The drive side arm is attached to the axle.
Certainly I've not had problems being offered a replacement non-drive side but I've never b*****red that side up!

Little tricks to remind you which thread is which:
Right is right and left is wrong

Always unscrew towards the back of the bike and tighten towards the front wheel

Put your cranks facing forwards and whichever side you're on put the spanner at 12 o'clock and push towards the back wheel to loosen and the front wheel to tighten.

When doing the pedals up start the thread by hand then with the bike upright put the pedal spanner on the flats and backpedal holding the spanner steady. The thread will do itself up.

Nice one cubist

I always do pedals up by hand until I can't tighten any more then just use the spanner to put the last 1/2 turn on. There's no need to tighten more than that as they're self tightening - that's why the left one is revers threaded.
