THE PURPOSE
FRONT AND REAR SPECIFIC WHEELS, OPTIMIZED FOR COMPLIANCE UP FRONT AND HIGH IMPACT STRENGTH OUT BACK.
Working with Downhill riders Becci Skelton (Rocky Mountain UK Enduro and DH) and Tom Makin (Steve Peat Syndicate Racing), the H_IMPACTs were well and truly put through the ringer. Although not designed for the demands of Downhill, sitting instead between our Trail Wide and Enduro Wide, we wanted to ensure they were more than tough enough to handle anything an alpine trail can throw at you.

The V1 rims survived months of North Wales finest rocky tracks, until Tom finally cracked them at Ard Rock 2018. Although he’s no lightweight, it highlighted that we needed to try harder. So, Pete and Luisa, with advice from John*, looked closely at competitors’ carbon options, then tested a further three ideas in the fibre schedule and material choices. The V4 prototypes which resulted were 21% stronger in our laboratory impact tests for the same weight and dimensions whilst also using compliant low-temperature V:Absorb resin. Tom is still trying to break them, unsuccessfully.

“I’ve been using the V4 All-Mountain carbon rims for racing and riding; trail, enduro and even downhill for over a year now with over 3,000 miles logged. I was told by the guys at HUNT to give them a hard time and challenge them as much as possible – I’ve been doing exactly that and they’ve stood up to every challenge.

They are lightweight, stiff, responsive and strong and I would have no hesitations in recommending them.”
Tom Makin – Steve Peat Syndicate Racing.

H_IMPACT DEVELOPMENT
Not only did we get the wheels out under riders for real world testing, we also lab tested them to ensure they were as tough as possible. We dropped 15KG from increasing height onto a bare rim (no tyres/tubes/inserts etc) until they cracked.  We had the benchmark set by a market leading impact tested carbon Enduro rim in our sights.

Not happy with the V1’s, we tested further until satisfied with the results. The V2 was a step in the right direction, but still it was below our expectations, so V3 was born. A little closer, but not close enough the team once again examined other rims and worked with engineers to alter the type and orientation of layers, thickness of the bead and resins used.

With the V4 we achieved our goals of a consistently high impact strength wheel, ready to take on the abuse of any mountain.

FRONT AND REAR SPECIFIC LAY-UPS 
Front rim weight 460g (27.5) – Excellent handling and vibration absorption due to the lower material density lay-up, matched to 28 triple butted spoke count to improve compliance and grip where it’s needed most.

Rear rim weight 530g (27.5) – High impact lay-up with extra material matched to the higher 32 spoke count. Greater impact strength, better stability and more precise tracking at speed.

V:ABSORB RESIN
We put a huge emphasis on durability for the All-Mountain rim – Unidirectional T24/30 with 3K weave reinforced spoke holes, Extra thick sidewalls for impact protection and V:Asborb resin to reduce vibration.

V:Absorb resin blends in the carbon layering which cures at a lower temperature. Lower temperature resins are less brittle meaning they have greater resistance to impacts and dampen vibration more effectively.

HUBS AND SPOKES
The hubs on the HUNT All-Mountain wheels have been chosen to increase stiffness, bearing durability and overall strength of your wheelset.

On the rear, the RapidEngage MTB hubs with a superfast 3° engagement, means you’ll be able to put the power down straight out of the corners.

Often overlooked, spokes play a key role so we use cold drawn J-Bend Pillar spokes, made from Sandvik T302 Stainless Steel. Triple butted 2.0-1.6-2.0, then 2.2 at the head for patented Pillar Spoke Re-Enforcement (PSR).
