I bought my used bike here for a very good price and it's served me well. After about a year the "Steuersatz" became wobbly. I went to another store (Rad-Spannerei) and they quoted me 70 EUR to fix it, if it was broken when they looked inside, 25 EUR or something if not, just to look inside and tighten it and/or replace the ball bearings. They got cagey when I asked for a written price estimate for that and some other things I wanted to have done, like truing up the tires. They even seemed suspicious as to why I would want a price estimate for the repairs. It got weird so I left.
Then I went back to Kubi's. It's simple and no-frills there, but they clearly know bikes. The guy there looked inside, saw the screw inside the Steuersatz was loose, put in some new ball bearings and tightened the whole thing up. He refused to take any money.
I LOVE KUBI'S. And I'm never going to Rad-Spannerei again. They have a terrible attitude and inflated prices. read more
