Ease of use of the site was good and email communications after the purchase were great. I?m not sure if the bike was assembled by GT or Lux, but the chain guard was not fitted correctly and was rubbing on the back of the chainring and crank. A couple of the screws were cross threaded for the chain guard as it did look like a ?one size fits all? type chain guard, one of the screws looks like it didn?t line up so the surrounding area is very scratched up. The spacers on the back of the rear brake that have the concave surface were 90 degrees out, which could easily come loose and cause the brakes to malfunction as they would be quite loose. Overall I would use them again, but would definitely hope for a better assembly of the bike next time.
