I've taken a look at the bikes.
The Combi Disk doesn't seem to be a good choice. It seems all they did is take a cheap bike and slap Juicy 3s on them. Acera/Alivio level, and Suntour components with a Juicy 3? The Combi R has a better component mix.
Other things though. I've never heard of this brand. However, the mere fact does not mean that they don't make decent bikes. However, you might have a hard time finding a community of owners. Also, a quick look on mtbr reveals that there are NO reviews for the Combi series. Simply something to think about
