BCD Bullseye Cranks

[Cherrymatt]

Hi folks, I was just wondering if any of you technical guru's know the BCD for Bullseye mountain bike cranks spiders. I am thinking of making the Pace single speed as I reckon it would be perfect for the trails in the local woods around where I live (during the week) in Denmark.

I am not being lazy its in the shed at home in the UK so I can't measure it

110 everytime, or get a TA ring and ditch the spider totally.

TA chain ring, do away with the spider..... Interesting does it bolt directly onto cranks??

I think its the TA cyclotourist rings like this:

even come in 1/8 to match standard singlespeed freewheels or 3/32 to match shimano multi cassettes.

It can bolt directly on to the crank arm without need for a spider. These often come up on ebay in many sizes. I'd check with the boys on MTBR or with Bullseye themselves to make sure it is the cyclotourists that fit as there are a number of TA bolt patterns but this is the one that I seam to remember BITD.

Just found this on Bikepro:

The round adapter plate was first devised to permit chainrings from a French company called TA to be bolted to it directly using a TA Cyclotourist chainring.

so you're good to go!
