Hi, I bought a Procarbon downtube protector off a mate today but there's something weird about it. It's got a line going down the middle on the inside, a small bump, meaning it doesn't go right onto the frame, but it only sticks up ~1mm. Is this normal?
Also the stuff on the inside of it is a smooth material and is glossy black, but on the old protector I had it was rough and a grey colour on the inside.
Just checking if this is normal, or if it will affect the strength of the protector in any way so I don't be a pussy about it and ride my bike properly
Thanks
