Good Choices Please...Doh!! Tyres that is. And lessons in computer use might be helpful....anyway I've ordered a BT021 to replace the front BT021 which has a thrupenny bit profile. The previous owner said the front tyre lost 'a couple of pounds a week...', three psi a day in reality.... Also got progressive fork springs from Realm engineering (£69). Left fork untouched since new in 1990, right fork was replaced in 2006. New springs and oil should put them back in balance.
