Silverback Sphere 1


Silverback Sphere 1.jpg

The Sphere 1 is Silverback's reimagination of the hardtail with plus sized wheels. It features 3.0" tyres to add grip, stability, and comfort. The Sphere makes use of the wider Boost axle spacing to stiffen the larger and heavier plus wheels and tyres. The 100mm Manitou Magnum fork sits at a trail-friendly 68 degree head angle. The reliable combination of a SRAM 1x drivetrain and Shimano's SLX brakeset round off the bike.

Verve Infocrank


Verve InfoCrank 1.jpg

The Verve Cycling InfoCrank is a relative newcomer to the power meter market. It is a crank based power meter which boasts left and right measurements. The unit is said to be super accurate and highly durable without the need for continuous recalibration. The cranks themselves are cold forged aluminium fitted with Praxis Works chainrings. Model Tested: InfoCrank 110 BCD M30.

SRAM NX upgrade


This is an upgrade I recently did to my own bike and, even though it is not a full SRAM NX drivetrain review, I thought it may be of interest. The upgrades includes a SRAM NX cassette, rear derailleur and chain with a GX shifter. Due to the marginal price difference between the NX and GX shifters, the local distributor has decided to not stock the NX shifter for now.

Unlike the rest of SRAM's 11-speed range, the NX cassette does not require a XD freehub body and therefore fits in place on a regular 10-speed hub, making upgrading simpler and cheaper. This does however mean that SRAM were unable to provide the same gear range, with the smallest sprocket on the NX cassette being 11T instead of the 10T found on other SRAM 11-speed cassettes.

Having spent many hours riding SRAM's more premium 11-speeding offerings, I'm interested to see how this budget upgrade compares.
