With our acclaimed “point and pedal” geometry, our frames are built by some of the best builders in the industry.
As we’ve already said, this frame is the ‘Sirius for the single minded’ – the geared crowd who want a high performance, lively frame with no-compromises so Reynolds 853 features once again.
The main design elements of the award-winning Sirius have been retained with one major exception – the dropouts. We’ve opted for a cowled design to give us a large weld area for the stays and also included a replaceable gear hanger, just in case. One other subtle change is slimmer seat stays.
These two changes shave weight (without compromising strength) and give you the trail-hound you’ve been looking for.
