... 110 BCD, silver or black, for 4 bolts cranks

? 4 bolt 110 bcd? Think you might struggle with this

Re:


Like this, 4 bolts to attach the spider on the crank (i know 110BCD is for 5 bolts chainrings )

Do you know which middleburn cranks you have? The earlier 4 bolt versions have flat arms and spiders, the later ones have curved arms and the spider for these is different. Looking at the pic above, I'd say that's the wrong spider for those arms, but I could be wrong.

I do have that spider and self extracting bolts in silver though.

Re:

I've a lot of arms I'm looking for a flat spider for flat cranks (to put on my road bike), i've the right 130BCD spider, but a 52/53 ring is too much for me

Sorry, I'm afraid I've only got spiders for rs3 or rs7/8 cranks. Good luck with your hunt.

I could be wrong, but I thought that the RS1 and RS2 spiders could be swapped, but the RS3 is more sculpted to allow for the profile of the arms. The RS1 and 2 arms are flat and therefore don't need a sculpted spider. They will fit in terms of bolts, but not sure 100% that they will create the right chain line. I have tried myself in terms of fitting, but never used on a bike, so can't speak from experience, just theorising.

The RS 1 has 5 bolts as opposed to the 4 bolts on the RS 2 & 3, I fitted my RS2 (cracked drive arm) spider onto my RS 3 as I wanted a silver instead of a red spider on it (yes I know I'm a tart :roll: ) & the 2 spiders were identical apart from colour.

Fair enough, just thought that from experience the more sculpted spider would be needed for rs3 cranks, can't quite remember if it fits rs2s.
