Bad service, advice mainly to sell stuff, expensive.
Went to Viking cykler simply for convenience as it is close to work and the LBSs around where I live have typical 10-6 working hours, so pretty much impossible to deal with.
I needed a replacement for the rear cassette, for which special tools are required. The keeper tried really hard to sell me first a full service and then a new chain as well, even after I told him that the one that is on was only two weeks old. This went on for at least two minutes, but I remained firm.
When I picked up the bike, he told me a wild story about my front derailleur, rust, issues and so on - it is as old as the bike, 6 years, but worked perfectly fine (Deore).
Now I know, why. They had tried to adjust it and tightened the wire so much, that the chain won't go on the smallest chain ring. They also messed up the rear derailleur, which as of now does not work properly.
Finally, for the price paid, the tool was within reach. I know exactly what to do the next time, when something needs to be fixed and requires a special tool. And it does not involve Viking cykler.
