Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

2018 Genesis Tarn Frameset

Season:2018

Brand:Genesis

Code:VARGNA24GRN

As blank canvases go, they don't come much more versatile than the Tarn. The long 'n' low frameset is the perfect way to get creative with your own 27.5+ custom build! A fully rigid mile eater for bikepacking adventures and off road touring? Maybe a burly build with plus size tyres for taming Lake District fells? The Tarn will do all of that and more - you decide. 

Spec with either 27.5+ or standard 29" wheel/tyre combo for ultimate trail versatility. Still a fan of a front mech? It'll happily take a top swing or side swing derailleur. It's dropper post ready too, with a 31.6mm post diameter and a port for stealth dropper routing. There's also a shim to take a 27.2mm post if you want to run a conventional pin with a bit more comfort.  The frame comes supplied  with a new, 120mm suspension corrected, full carbon fork, there is boost spacing front and rear (110x15/148x12mm) and Shimano's brilliantly simple E-Thru I-Type rear axle comes fitted as standard. Both Shimano direct and old type hangers are included along with a sealed bearing headset to round up the carefully considered details, the rest is down to you!
