Proper, actual bikes rather than BSOs? 4 and a half.
Started it all off with a Cube LTD Race, 100mm. Great thing, and having a decent bike just as I was getting back into it was the difference between me sticking with it and me jacking it in.
After that came a rather large step forward: Pronghorn XC-SW Carbon. Ridiculously light, ridiculously expensive, and (to my eyes only, it would appear) a thing of handsome majesty. It rides fairly well too.
That was swiftly followed by my first road bike: Look 566. Nice and light, nice and fast, nice.
Then I had a hankering for something a bit beefier than the carbon Prongy, so I went for an alu one: Pronghorn PR6 Trail. Fox Float 36s, Kashima, FIT, all that jazz. No idea how, cos i didn’t spend any real money on bling weight-weenie stuff, but it weighs in at 28lbs. As a result I’ve not ridden the carbon one since. A proper do-everything-I-can-imagine-doing-on-a-bike bike.
Now have a PR6 Trail frame as well, just as a back-up in case the other one fails. Pronghorn don’t make them any more, see, and it’s the best bike I’ve had the pleasure of riding and don’t want to swap for another.
