OK, I'll admit it, I haven't ridden much for a good while now, so it may be that I'm just out of shape, but today I rode about 25-30 miles on my On-One scandal 29er & my back is killing me, when I get up it takes a while for me to straighten up.
I'm 6' (long in the leg if anything) & my bike is the original scandium frame in 19" using a 105mm stem, could it be the reach causing the problem?
If not any bright ideas as to how I can sort this, I would like to get back on the bike more again as today was just so much fun I could of ridden all day (I think the weather helped!), but I know the back will be worse in the morning so it puts me off.
Cheers in advance.
