I have just bought a Thoroughgood Heather Moffat saddle. My old saddle did not encourage good position, I had to fight to keep my legs under me, however it was comfy and I did manage with it for 3 years. I have been riding in the new saddle for 6 days and I am finding it hard to balance. I am advised that my position is much better but it doesn't feel right. How long can I expect for this transition to last, I feel like I'm back to square 1?
