Hi,
I got my boy a Spesh Rockhopper 18 months ago for his 10th birthday. Changed stem length and inverted the new one. Adjusted seat for knee / pedal line. Sorted reach on the brakes, originally V now Juicy 3’s. But the major thing was changing the spring in RS Tora forks, softest spring from TF Tuned. Fork now works very well. He is bnult like a racing snake and can throw the bike around pretty well. 2 laps on Sunday round Cannock and he has no probs keeping up.
Daughter has a Spesh 24″ Hotrock at 8 yr old, loves it, forks work very slightly, replaced the tyres with Conti Explorers, light enough for her to move around and have a great day out.
He only wants a road bike now though – Pro-lite The One 650c wheels at £750, I think he needs to get a job!!
