Middleburn RS 7 swaps

[Wold Ranger]

I need to swap a set of Silver ISIS Middleburn Rs 7's with CD 5 arm spider in red for a set of ISIS Race face CD cranks in good order. Black or Grey or Silver (Blue?) This is for the Sunn Xircuit Comp build which used Race face or Syncros.

I still have my RaceFace North Shore ones, they are silver, 5 bolt and ISIS

Cranks

Was really after the Turbine or Next style, are these mint and 94 bcd? they did five arm in 94 and 110.

 

[THEFALLGUY]

is 94 the modern one? they take standard size modern rings if that helps. Not mint though

Cranks

Modern? 94mm bcd is compact drive, the smallest one, 110 is the other, they were on the go at the same time really.

 

[THEFALLGUY]

Whats now then? doh is 4 bolt different again?

Everything is micro drive now though isnt it? 22 32 42

the old ones wer 26 36 46 werent they?

anyway the NS cranks are probably to scruffy for what you want, please ignore me

Drive

Compact drive is 94 bcd 5 arm, 4 arm modern is 104 bcd, there is also slightely older 110 bcd five arm, 4 arm XTR has its own bcd just to confuse things, 4 arm is not compact drive, its 104 modern. Confusing ain't it!
