Hi all, new to road biking and this forum. I bought on impulse a Ribble sportive road bike, nearly new. I have been out on it about 6 times the last two rides being 49 and 45 miles. I live in a hilly part of the Uk and am struggling to get up some short but reasonably steep hills. I end up out of he saddle with my legs just about turning , I haven't stopped yet but was mighty close twice today. Now this is my fault for not doing my research beforehand but it turns out I think have bought what i thought was a compact but turns out is a double. It has a 52/39 up front and a 12/23 at the rear. I think his may be the cause of my problems, do I need to a. Give up cycling b. get another bike c. Change the rear cassette or the front cogs. If so what could get that would fit and give me a significant benefit, would I need to change the chain and is it a DIY job. I really hope that my pathetic attempts at hills and speed overall is not just down to me, please. Help and thanks in advance.
