Looking for some help from anyone with experience of sizing an S5. Sigma Sports have the great deal below, 45% off 2018 model. It’s a lot of bike for £2,600, I’d be stretching the budget to that but there’s no way I could ever afford a £4,700 bike at that price.

I’ve never had a Retul fit or anything so looking for some help. I am 5’11 with a 34.5inch inside leg (yes I have giraffe legs). Any advice on what size I would need? I will then go and speak to the good lady wife her indoors and see if I can make this work...!

Happy to provide any other measurements if they will help. Thanks in advance!
