Bottom bracket interchangeability

Reading the info available on the web for a Ruktion chainset a Howitzer BB is the only one you can use.
It has an ISIS/octalink style splined axle and external bearings, most other external BB's have no axle, it's part of the chainset
Pics of your chainset (not in the frame) & BB will help

Howitzer is the only BB you can use with those cranks, unless another manufacturer does a Howitzer spec BB, but I don't think anyone else does them apart from Sram/Truvativ (been wrong before so might be worth a quick internet search)
cheers for the help
this thread seems to echo what you say somewhat
ah well
what about the cups though?
i was thinking maybe if the bearings were the same just change the cups? i mean how different are external bb cups? ( i want red ones, or new ones as mine are scruffy)

I would think that the cups on a Howitzer BB are unique (judging by the design of the rest of the set up being non compatible with anything else) and you are stuck with the same as you already have.cyfa2809":1slat4kn said:cheers for the help

They certainly look much chunkier than any other regular external BB cups I have seen
oh you reckon?
i juat had a look on google at a few and the width varies
would you know what bearings are quite common for external bb's?
providing mine have a common size and the angle contact is similar or whatever it might be possible
the bearing doesnt use the whole depth of those cups by the way

Ahh, you should be able to get fresh bearings from your local bearing supplier if you take the old ones to them, most are fairly standard sizescyfa2809":1yqbcj69 said:
Didn't realise the bearing doesn't utilise all the space in the cups, not had one of those in bits yet
