apologies bit off topic but why the change in design from the earlier one piece spiders then removable rings to having spider part of large ring, this is still all fitting to square taper axle so just wondered on benefits ?
there are no benefits, just 'Faff'.
'Faff' is the new word to describe the 'new' that you must have before you even look at a bicycle let alone ride the damn thing.
'Faff' is what stops the spontaneous ride. 'Faff' can be be found in modern bikes taking up to 98% of a new bikes' design. Its in the pivots, the suspension settings, in between the 10spd cassettes, stuck halfway down a supposedly sealed shifter cable...
Faff has been known to cause the use of excess width riser bars and body armor for 'a quick blast'. Faff is also found in trail centres making up a good proportion of berms.
Faff has been with us since about 1996 when, under an EU directive, it had to be included in all new purchases which included cars, bicycles, TV's and so-on. Once perfectly good items that had a serviceable life of up to 30 years suddenly went wrong overnight due to 'Faff'. New purchases had to be made which included Faff, which we were told and assured about, they were the be all and end all of purchases, you wouldnt need another.
Of course, those new purchases became obsolete overnight as new Faff was available with the old immediately disintegrating rendering tools and repair shops redundant.
You only have to go to car-boot sales and recycling centres to see the amount of faff filled products being dumped or struggling to be sold...
