I have a Team plProfessional with the oversized rivet head. The saddle is much lighter thsn the chrome steel railed versions that ai also have on my bikes. The rails are non-magnetic and finished in a fsatin black finisk, so I assume they are Titanium. What I found a bit strange is, the csntle has bag loops on it that I don't really expect on a "Tem" Pro saddle. Was this an oversight by Brooks? I am also curious what years was such version of the saddle issued by Brooks.
