It depends on what the law would hold in UK or its dominions. In the U.S. you would be entitled to notice of the charge in advance of paying; and to the right of return of parts. In one sense, by telling you the items were discarded (even though you say they were dispossessed), you now have no way to prove that they were not defective. But, you do have a legal right to replacements of equivalent qualtiative and monetary value. Now you say the pedals were worth 8, but is that what you were charged? Or just your own estimate. If you can show a comparable selling for whatever price, you can support the claim that you lost in the deals by also showing the trap pedals selling at around 70. Your post leads me to wonder if you even went to a legitimate service provider. It is hard to imagine any knowledgeable bike repair person, or even amateur bike rider, that does not appreciate the comparable value of metal pedals vs plastic pedals...unless those plastic pedals were composite material in construction. You need to challenge the deal you got and compel them to show equivalent of better form and function and material. Or you will be back somewhere else, soon, for unbroken pedals; or in a doctor office for nut crunch.

Oh, by the weigh are you sure you want to claim 70 for bike pedals? You might want to tone that down to something more consistent with the price of you bike. An arbiter of you claim might look unfavorably upon the likelihood that 70 value pedals would be fitted on a bike not worth over...well a very very pricey bike...the kind that average people simply cannot afford and do not need.

There is no way we can know for sure what happened. Maybe he thought the rubber was worn off the pedals. Maybe he was new on the job and didn't know about metal pedals. Maybe the bearings were worn out. I would find out who did the work and ask him why he did it and see if he has a reasonable answer.

It also seems strange to me that you would hire someone to service your bike. Everyone I know is easily able to service their own bike.

If you did not request him to change the pedals, you were scammed! Demand that he find them and put them back on or give you new metal pedals. It was their mistake not yours. Good Luck

Sounds to me like the metal pedals may have been bent or way to worn for your safety so they replaced them. And by bin he probably meant scrap bin.

Do you have a written work order? Was he instructed to even touch the pedals. He - or one of his buds - liked yours. Don't get mad - get even.

Either way he owes you for them.

yesterday i took my bike to get a service. it came back, everything was in order, although apon looking through the recipt when i got home i realised that the was Pedals - ￡8:00

the guy has taken off my ￡70 metal pedals and replaced them with some crappy plastic pedals,

anyway, i went back the next day and asked for my old pedals back, he said that they had already been put in the bin and he didnt have them anymore!?!? do you has he scammed me or was it just a mistake. ?
