Mobil XHP220 is specified for high temp, Hi PRESSURE uses... your bicycle will not produce either in a bearing, as long as the bearings are properly adjusted.
the XHP grease is available in a range of NLGI specs... 2 or below is ok for bicycle use.... i've had best results using 0 or 1 grade in low load environments... better lube FLOWBACK is the reason for a thinner grease in a low temp. environment.
Mobil Does Make some of the best greases i've used.... there was a Mobil Marine grease that was used on ExMark Mower blade spindles that was INCREDIBLE., but was WAY too thick for most applications.. it was specified for Valve shafts and threads in Undersea Oil Well capping use.... the mower shafts run in a high water and chemical bath environment... (FERTILIZER!)... most greases fail in a matter of weeks...that Mobil stuff made disassembly two years later just like the day it was assembled.
