Was not sure when I was going to make it to Bali, but no problem, Infinity just gave me a list of what they were doing for the week and I signed up for the one that took my fancy via email. All the staff both admin and driver/guides were great - friendly and relaxed.
Infinity seem to be the only real option for experienced mountain bikers (Trailblasers a notable second) but infinity certainly have the best equipment that I saw during my research.
Perhaps it was because I went for the "Volcano Trail" (classified Difficult compared to the Trilblasers' "Batur Crator" ride classified experienced/multi level), but both the attending riders and the trail itself were one step higher quality, when comparing this to the Trailblasers' day trip.
In short, well setup organisation, a little more expensive than some, but very good quality equipment and the trail rides are good with enough technical sections to keep most people busy
