Alpkit’s sister brand Sonder have released their first XC bike, the Sonder Dial. This aluminium hardtail slides into a now comprehensive off-road line-up as their most affordable mountain bike to date. Pricing starts at £299 for the frameset, with three complete builds available too. Here’s a quick intro.

Sonder Dial XC MTB

The Sonder Dial 29er hardtail MTB gets a 6066 aluminium tube-set with a race-inspired geometry. Sonder say they’ve engineered some vertical compliance into a low profile flattened top tube for comfort on long rides, while keeping it laterally stiff. As such, the frame has boost rear end spacing (12mm x 148mm).

S-XL frame size range caters to riders from 5ft 2″ to 6ft 2″+

The Dial’s head angle is steep at 69°, paired with a 74° seat tube angle. Chainstays measure up at 430mm across the S-XL frame sizes. Reach stretches from 410mm in small up to 475mm in XL.

The Dial gets a threaded 73 mm BSA BB shell

Seat tubes start at 395mm in small, growing to 520mm in XL. Though none of the three complete build options come spec’d with a dropper seat post, those seat tube lengths should permit use of decent length droppers. Cable routing is internal, including a Stealth port for a dropper.

The Sonder Dial is available as a frameset only for £299, and also in three complete build models. The Dial SX Eagle build is Sonder’s most affordable XC hardtail, retailing at £999.

The Dial NX Eagle build comes in at £1399 sporting its namesake 12 spd drivetrain. It gets the same wheelset and tire combo as the SX Eagle build but the fork is upgraded to a RockShox Reba, and the brakes to SRAM Level TL.

I wish I cared about this. There are enough companies specing NX/SX crud on their bikes. The race to the bottom continues

The GX build is a great value for someone looking for a HT.
