Industry Nine's Hydra Classic mountain bike hubs are currently discounted to £327 at BikeTart – a 50 per cent saving on their RRP of £660.
While the updated Hydra 2 hubs were released earlier this month, the first-generation model is still a high-level performer at the heart of any wheelset, especially with the savings on offer.
We tested the hubs alongside Reserve's 30 rims and were impressed by their quick engagement thanks to a 0.52-degree freehub engagement angle.

What are you getting here?
As mentioned, these are the first-generation hubs made in Industry Nine's North Carolina machine shop.
They feature a milled construction from 7075-T6 aluminium and are anodised in-house, with Industry Nine offering a large array of colours.
The front hub weighs in at 165g, while the rear is reasonably light at 289g.
Shimano and SRAM-free bodies are available, with Boost and non-Boost options available in the deal.
There is also the option of six-bolt or Center Lock rotors, depending on your preference.
If you like loud hubs, the I9 Hydra should be on your radar, with the ludicrous engagement angle resulting in a high-pitched buzz as you freewheel.
The hubs are home-mechanic friendly and can be serviced without any proprietary tools.
Despite not being the latest model, Industry Nine backs the Hydra hubs with a two-year warranty.
