The Kinesis Tripster ATR Ti V2 Dropout is designed for Kinesis Tripster ATR Ti V2.The Kinesis ATR V2 is adaptable between quick-release dropouts or 142x12 bolt-through dropouts. The complete bolt-through set is no longer available. We do still offer the right hand only however the manufacturer of these dropouts has changed the design and it will need a different length bolt through axle to what was originally fitted to the ATR V2. To fit the new right-hand bolt through dropout you will need the Kinesis 163mm bolt through axle (available on our website).
