Excuse me hijacking this thread Jess, but there is a very good chance that RK Chains will produce another batch of primary chains (Part no. 21190-37020) for the RE5 in 2018. They will NOT be cheap and, as each one will be hand-made, delivery will be er, 'leisurely'. (RK produced the original RE5 duplex primary chains back in the 1970's).
This order is most unlikely ever to be repeated. Please contact me to express an interest; as this is quite a costly venture, cash will be required up-front before the order is placed. Ideally, we need top get as close to 100 pieces as possible to make this viable, so if you could order more than one then so much the better. Remember that these chains do stretch; mine was pretty shagged after just 30,000 miles.
Email me in the first instance please.
