I took my bike in for assembly and she assembled it overnight and it worked fine. The bike came from Walmart and had a cheap part that she adjusted no charge a week later. It has been a year and I use her for all adjustments or part replacements, as I put alot of wear and tear on my bike. She is honest about what is wrong and tends to charge very little for labor, mostly just the price of parts. She will also watch your form and give suggestions on how you can adjust habits to make your bike last longer. I enjoyed that she taught me how to install my temporary bike rack and was impressed with her manner. I definitly suggest Cyclesport.
