I have one on the Roubaix. I have 2 stock Whyte saddles, funnily enough on my two Whytes a one23 on the Forme end a stock specialised on the single speed. The geometry is pretty much identical on all but the specialised and suits me fine.
I've got one on each of my two road bikes. I've sat on saddles that were a lot more uncomfortable. I'm sure that there are ones that would suit my bum better than a Spoon but I haven't found them yet. Try and borrow one for a trial.
Anything based on the Flite is going to be no good for me. I saved for ages BiTD. When the glorious day arrived I skipped to the bike shop and got them to fit the titanium railed loveliness there and then.
By the time I got home I hated it. No matter how I fiddled and adjusted it just seemed to dig in. Some days it seemed to dig so far in, I wondered if perhaps I should lube it!
Some weeks later I gave it to a mate who loved it, well, so he said. Soon after I began my love affair with the Selle Italia Turbomatic II, III and so on. I still don't use anything else.
If you are a real man try one of these.
I have a spoon and a brooks, on different bikes. If I could afford I'd have brooks on all. Spoon is ok but not the best, just better than what was on bike when I got it.
