Seagrade, I thought of that. Recently I put the CJ up for sale with both forks.
Zero added interest, people didn't seem to care whether the steel fork was included or not.
Now whether this is due to the general downturn in the road bike with rim brake market, can't say.
I know I'd be interested if someone listed a bike with two forks for sale. It's just something you don't see that often.
