I've persevered with Isis…now time for a change but what are my options?
It looks very tight around the bottom bracket area so will an external bearing throw everything too far out?
No, standard HTII are 68-73 width, get yourself a slx or xt, I think the shimano system works better than other types of fixings for the cranks. You will probably need to change the bearings more often, but it is a piece of piss to do, and they are cheap from the German shops.
Most say that they can’t feel the difference in stiffness, but I defiantly find them better, but then again I am aPosted 4 years ago

External will fit a 73mm shell just fine.
As to which? Not much anybody has a bad word to say about the recent shimano HT2 cranks.
I’ve had good experience with FSA Megaexo, which uses an identical clone to the shimano BB system (both road & mtb cranks – all have been good).
Hope BB are (in the long run) a worthwhile upgrade. Mainly because they have better sealing over the bearings, so they last longer. I think there are other sealed BBs available now (gusset?) for less though. The key thing being the extra seals.
On the whole I find external BBs nicer, as they are definitely a stiffer setup than the square taper / ISIS systems. More handy for us heavier riders.Posted 4 years ago
My (old style) cannondale Jekyll came as stock with an Isis bottom bracket and crank. They’ve been changed since then, reasonably regularly, like for like. Recently, I’ve been having a few problems with the non-drive side arm working loose and needing to be nipped back up. Last night the non drive side crank arm worked itself loose and no amount of tightening of the bolt resolved it so I expect it has deformed.Posted 4 years ago
I’m Just looking at what I can fit as an improvement. I recall from the last purchase that the bb size is 73/113 so will an external bearing system fit? It looks very tight around the bottom bracket area so will an external bearing throw everything too far out?
Any advice welcome.SpeshpaulSubscriber
check the deore has a BB the slx is without.Posted 4 years ago
I’m a big fan of middleburn but at these sort of prices and the quality of the deore you’ve got to want the Middleburn or go second hand.
