Halfords have been pretty helpful when I've gone in to buy basic bits for the bike e.g. water bottles, tool kits, etc - not that complicated.
However, I would never buy a bike from there again unless I decided I had money to burn getting it set up elsewhere. Last year I decided to treat myself to my first ever road bike, and after looking at reviews and asking for advice, I settled on the Carrera Virtuoso as likely to be the best bike within my budget.
I'd never bought a bike from Halfords before, so along I went, the only one my size that they had in stock was the display model, but they told me to come back two days later and collect it after it had its full 'safety check'. Being thorough, I thought...
Anyway, picked the bike up, nice and shiny (I'm clueless about much else!) On my trip home, realised the gears were set up incorrectly, so went back and had them adjusted.
On way back home again, realised that the gears were still wrong, but different ones were problematic this time. Store had been closing as I left, so went back the next day.
In the meantime, I realised that the back brake would gradually come to rest against the rim on one side, with a huge gap on the other - incorrect adjustment. So I pointed this out too.
Lo and behold, when I got the bike back it was still set up incorrectly. So I decided to make what seemed like a smarter move, and take it to a different branch. They expressed surprise at how strangely the first store had set up the bike, and improved it slightly, but not by much - the brake problem was still there, and the gears still slipping/failing to shift in places.
So back to store number 1 as closer. This time I spoke to a more senior member of staff (I think) who listened to my rant (extremely frustrated by then!), agreed that it was unacceptable and wrote on the form that the adjustments this time had to be
perfect, as I told him that otherwise I would return the bike. As if anything less than perfect should be acceptable anyway...By this point my confidence had also been knocked by seeing a printed list behind the counter for people on work placements/experience, or similar, which included bike building.
Needless to say, the bike on collection was no better, and they ended up having to refund me for the bike when all I wanted was for it to work. Ended up buying a secondhand Carrera Vanquish, decent bike for what I need and no messing about with Halfords, but it should never have come to that.
Since then, I have come across a kids' bike bought from Halfords years ago, and used only once as the child had an accident on it. On looking at the bike, noticed that the front forks were back-to-front. Scary.
Apologies for the lengthy rant, it's just one of those things that really annoys me whenever I think about it. Don't understand how these people can be employed when their incompetence puts people's safety in jeopardy, less serious in my case but other reports are horrendous.
Mind you, I have also had problems elsewhere, like the LBS who 'trued' my wheel leaving one spoke very slack, and then got stroppy when I questioned them...pity I didn't know any better and let it drop, as that wheel is now buckled with a broken spoke. Just wish it wasn't so difficult for the ignorant (e.g. me) to find somewhere trustworthy!
