I had a Cube Ltd which I found to be too nervy on techy stuff, and built myself a bouncer around a secondhand Canyon Nerve 140 frame. That now has 150 Revs on. I rode that for a while before realising that I still enjoyed the hardtail in certain circumstances, but wanted something slacker for trails, so I got a Soul frame and spacered the Reba off the Cube to 120mm.
I then mostly rode the Soul, and only very rarely rode the bouncer until a few weeks ago, when I dusted it off and took it out for a more epic ride.
I realise I was in danger of neglecting the bouncer. It taught me confidence where I lacked it on certain trails (especially rocky techy stuff which the Cube was simply scary on) and bizarrely this has translated into more confidence to tackle that sort of stuff on the Soul.
I took the bouncer to Philips Park last week, where I supposed I would be massively overbiked, but far from it, it was a scream.
So, from a latecomer, arthritic mincecore 50 year old, my mix of bikes seem to complement each other. Time will tell whether I ever “send it” big stylee, or whether the newfound confidence leading to a bit of airtime simply means I don’t ‘fraid what I consider to be the big stuff quite as much. 😀
