Do you have this in a 68/73 bottom bracket in silver?
Sorry, nope!

graphics on crank arm?
31 Jan 2020

Will this crank be like the one pictured with the older graphics? Or will it be like the new ones BETD make?

Also it says you only have one left, is it a 175 or 170 arm length?

Thanks in advance.
These are as pictured, we do not deal with BETD currently.

Chainline- alternative to Shimano GRX
31 Jan 2020
I am trying to find an alternative to the Shimano GRX cranks but they have an unusual chain line measurement (Ultegra 43.5mm, GRX 46.9mm, MTB XT 48.8mm). Supposedly this is to improve chain line for the equivalent rear cassette. How would I achieve this with the Middleburn cranks if at all? Otherwise I might go down the route of an MTB cassette/crank (can't get the range I want with road set-up).
Advice would be greatly appreciated.
You could replicate this with an outer ring by adding spacers, you would be unable to do so with an inner ring of course.

The GRX chainset simply matches the GRX front derailleur and therefore works seamlessly.

Can I use this as triple set up on Klein attitude
25 Oct 2017
Or would the RS7 in 170mm silver be available/ better - I note you have tandem cranks in this size or would these not fit?

As we do not stock this bike we would have no way of knowing I'm afraid.
