I recommend this product
ConsNot the cheapest
ProsBeautifully made and tough
I have been using an RS7 chainset on my mountain bike since 2001. They were to replace a Shimano STX crankset. I have covered several thousand miles on these cranks as I use this bike every day to ride to work on and I'm on my second set of chainrings. (slick shift hardcote ones). The crank arms are 7075T6 which is the strongest grade of Aluminium Alloy available and they are CNCd from billet. They are solid, really well made and in my case they are still as good as new at 14 years and counting! Very highly recommended.

What Middleburn Spider Do I Need To Pair With This Crank Set
09 Nov 2016
Crank set Middleburn product number: RS7-SQ-170-SI

Have a 5 bolt 46 tooth 94BCD chain ring to mount on the spider - just want to make sure I buy the correct one.


We only have one spider specifically designed for use with the RS7 crank arms in stock, these are SJSC part number 33745.

Can you tell me what the "was ..." price added to middleburn listings?

For example

This says was £219.99

But yesterday this was £99.99?

This is an error with our listings, this should hopefully be fixed in the next few days.
