I purchased my Triban 3 road bike on Monday. I've only ridden a flat bar so this was the time I've ever used drops. It was strange but I got used to it and I found myself riding in the drops more than any other hand position. I would like to use the hoods a bit more but I find it quite uncomfortable. When I'm on the hoods, I was expecting a bit of a more upright position but I still feel that I'm leaning forward into a more 'aero' position. I'm 5 foot 5 so ideally I would be looking for a bike around 52cm. The Triban only comes in a 51 and a 54 and I was thinking that I would go for the 54 as I am still growing and I expect that I would have outgrown the 51 in a matter of months. On the bike, I've got the saddle almost fully forward on the rails, because I noticed that when I went down into the drops, I was sliding forward and it was causing it to be uncomfortable. Will I benefit from a proper bike fitting and is this just a problem with the bike being too big for me, will it change when I grow taller?
