Bought our Grandson's bike from Halfords. As he'd grown we wanted to raise the saddle for him. Amazingly there was very little adjustment provided with the 'off the shelf bike'. Went to Halfords to purchase a longer saddle post only to find that Halfords didn't sell one for that bike even thouh that model was still on sale. However the Halfords assistant recommended tredz to us, looked up the correct part for us to order. Very helpful chap. Ordered the post and it fitted perfectly after chopping 75mm off the length.
