I only had one bike, until I bought it’s replacement. I then bought an Inbred frame and put the bits off the old bike onto the frame, so now I’ve got an FS & a HT.. I wanted a bike that I could use on the road as well as off road and didn’t really want to be riding my Stumpy fsr for road miles.
I already had a second set of wheels for on-road with slicks on – only cost about £130 including tyres, tubes, cassette & QRs.
I like the fact that if I need to do some work on one bike, I don’t have to get it done urgently as I can just take the other bike out if need be.
And although I didn’t think I would, I have actually been using the Inbred a lot more this winter off road to stop the FSR getting clagged up too much. Seems the sensible option, particularly for my ‘normal’ riding at Thetford.
