Downhill Mountain biking gear
We ride a difficult end overall kinds of landscapes. Generally speaking we ride regarding the center sequence ring-in these circumstances. Its less related to the mechanics, and much more regarding whats possibly coming, and quickly + dependable equipment choice. Whenever on big chain band, you could get caught out-by a short (or lengthy), steep uphill, and never be capable of getting a minimal enough gear to climb up it simply altering a corner cluster. I reserve the large one for easy predicable surface, or songs i am aware very well - for-instance sealed/gravel roads, made quickly songs with sweeping / bermed corners where speed is perhaps all important, and you are unlikely / have no need certainly to decelerate below about 20km/h.
If the track is steep and rough, i will be unlikely to run away from cadence before 'balls' - if you learn you (like many more) have a "lower center of gravity" than myself (for example. smaller brain and/or bigger balls), and you also run-out of cadence, then go with the top chain band. Also the sequence may be fallen much more easily off the top string ring - although on a well tuned bicycle this will perhaps not happen.
As far as sequence punch and derailleur jump - we ignore it. Its a mountain cycle made to be applied and abused. If you need, you may get neoprene coves for the sequence stay which will quieten it straight down, or put it in duck tape... I have never ever heard of derailleur damage caused by slap, but that is not to imply it doesn't occur.
