We added the longer Control Tech stoker stem and the Blackbird 48cm flat-top drop bars with dummy levers all from Tandems East. My stoker likes the drop bars better as it gives her lots of hand positions. She is fine on our Selle Anatomica saddles without a thudbuster. We also added a Topeak rear rack and rack bag. The rack bag has fold out "panniers" that come in handy to store extra clothing or a few groceries if we stop by the store on our way home from a ride. We love our RT2 and I hope you will love yours as well.
