Evening all, Fairly new to forums. Be gentle ???? A riding buddy has a query: How much does MTB bike weight affect/matter to the general intermediate rider ? More cross country / marathon type riding mainly. My mate is in the market for a new bike, He's a large human at 6ft4 & 103kgs and a budget limiting him to aluminium frames only. He recons he could drop a further 5-8kgs personally. Some people advising carbon / some aluminum. Would he notice much difference?
