Came across this Qball on MTBR.com, which shows you the versatility of this frame and different build styles. This Qball is a Cyclo-Cross bike. According to Wikipedia:
A cyclo-cross bicycle is a bicycle specifically designed for the rigors of a cyclo-cross race. Cyclo-cross bicycles roughly resemble the racing bicycles used in road racing. The major differences between the two are the geometry and the wider clearances that cyclo-cross bikes have for their larger tires and mud and other debris that is picked up by them.According to the Union Cycliste Internationale:
Cyclo-cross is a discipline run on 2.5 to 3.5 circuits, including clearings, roads, country lanes and paths through forests. The riders have to do several laps of the circuit over a period of no more than an hour. To make their way along steep paths, muddy tracks and artificial obstacles, sometimes the riders even have to carry their bikes.Also from the wiki I found the following:
The following are rules that have been put in place by the UCI that are either specific to or have particular effect on cyclo-cross bicycles. Bear in mind that these rules are not exhaustive, are only for UCI sanctioned events and may not be enforced at all cyclo-cross events.
- Handlebars must not measure more than 50 cm (19.5 inches) in width.
- Tire width may not exceed 35 mm and tires may not feature any kind of studs or spikes.
- Wheels shall have at least 12 spokes.
- The bicycle must not weigh less that 6.8 kg (15 lb).
- Disc brakes are forbidden.
In recent years, some cyclo-cross bicycles available in the consumer market are supplied with disc brakes, which violate UCI regulations, as a stock item. In general these bicycles have braze-ons to enable the use of cantilever style brakes instead. In the United States, disc brakes are now allowed for non-UCI events.
In some countries (including the United States, so long as it is not a UCI event) riders are also permitted to race in cyclo-cross events using mountain bikes (generally without bar ends), at least in low-level competition, but this is not currently allowed in events on the international calendar. It has been known for local races to be won on mountain bikes, particularly if the course is technical with little road or fast sections. However, for a traditional cyclo-cross course a cyclo-cross bicycle is the most suitable tool for the job.
