Hi Muirenn, sorry I didn't reply to you earlier, I was busy with uni exams over the past week or so.

First of all, thank you for being so helpful! I checked the position of the saddle I have right now and my friend that works at a LBS checked the seatpost, everything seems fine. The saddle I'm using right now is a Selle Royal Mach. My brother used it before me and he agreed that it's the worst saddle ever. The creaking noise the saddle makes no matter how tight I screw the seatpost bolts makes me believe that the rails are indeed bent.

I would like to try my luck with your Vesta if you're willing to sell it to me. If so, please send me a message so we can arrange everything

Thank you once again for the thorough reply, this saddle is keeping me away from the bike I spent 6 months building up so I'm getting a bit antsy to treat my butt with a nicer one
