Thank you for your comments, I will have a look round for a new saddle either Charge or X-lite one, I will leave the tyres on for the time being and put some bigger ones on next year, I wont go any higher than 1.8 as I do alot of tarmac riding which it helped if you run smaller tyres, I rated these Continental Cross Country 26 x 1.5 very good which it's excellent on off-road as mud never clogged on them and grip very well all surfaces.
