Regarding Andrei Padlowski's comment on the Campy 43t 151 BCD custom chainring by CT: "...it's not so much that the 43T is a weird size in general, but the smallest ring Campy made for their 151 bolt circle diameter cranks was 44T. so how did these guys fit one less tooth where Campy couldn't (didn't ?) ? ...perhaps they didn't countersink the bolt holes which would be the first things to cause interference, but ... i have no idea....."
Here is a jpg closeup of the polished-finish 43t 151 BCD chainring sent to me recently by Mr. Tetsu Takeuchi who is in charge of overseas sales for ct' special ordered chainrings.

Mr. Takeuchi said
"...Price for polished one is $126 plus shipping fee($15) by EMS. Alumite finsh one is $105 plus shipping fee($15) by EMS. If combined (2 chainrings) together shipping fee will be approximately $20. Due to frequent rises of the materials, quotation of ct's cainrings has to be raised from April's orders, however, requested orders made within March this year apply old quotation. Payment method is paypal."
