I'll have a look now at spa. Been trying to find both (36 and 46) just through general googling but is a bewildering choice without ever being quite right so far.Spa do an excellent range of replacement rings. Surely that's easier and more cost effective?
What did you have to tell him that for?Be warned when removing chainrings that the worn teeth can be razor sharp and if your allen key slips you will loose some flesh. Always rotate so if you slip, your finger go in a safe direction. Long handled allen keys are safer than the L shaped ones.
There's not much wear on either rings. Shimano teeth are like that to aid gear shifting. It does confuse a lot of people. If the rings were worn then the teeth look more shark tooth like.
Ah. I see the problem.The 120 bcd seems to be the real problem when it comes to replacing individual chainrings. Very limited range.
Thanks all for heads up on Spa. Chap was very helpful. Unfortunately due to the rarity of the 120 bcd, nothing doing until Hallowe'en!Spa cycles should be able to help with new rings. Give them a call
Bit surprised your chainset has 120mm BCD. Suspect the Spa Cycles guy was too.The 120 bcd seems to be the real problem when it comes to replacing individual chainrings. Very limited range.
This.I'd be tempted to get a replacement with a bcd you can get spare for!
