Seatposts that go up and down. Seatposts that stay at the same height whilst being incredible light. Waterproof jackets from arguably the most respected brand in MTB clothing. They’re all here.

The online bikey bargains just keep on coming. This week’s Dirty Deals may go down in history as one of the best ever collections of discounted offerings for mountain bikers!

Okay, that might be overstating things ever so slightly. Suffice to say, this week’s Dirty Deals are well worth your eyeball time.

Brand-X Ascend Dropper Seatpost – £139.99 – £109.99

Brand-X have brought out a dropper post and for limited period they’re flogging it off at discounted price. To be frank, even at full RRP this post is something of a rival-less bargain, so with the current 21% discount it’s something of a no-brainer. Buy it as your first dropper, buy it for your winter bike, buy it just a spare dropper for your normal bike. Internally routed frames only, 30.9mm or 31.6mm diameters, cable remote, 120mm drop.

Get in their first while you can and pick up this dropper for only £109.99!

Endura Stealth II waterproof jacket – £169.99 – £109.99

The Stealth was “one of the world’s first full waterproof, breathable soft shell jacket specifically designed for cycling”. Well, there you go eh? You don’t often see Endura stuff in the sales – it’s a premium brand that guards its distribution carefully – so whenever you see some of their stuff in a sale it’s time to get busy with the basket. Externally seam sealed soft shell fabric, ultrasonically welded seams, waterproof zipped pockets and reflective trim.

This jacket isn’t available in loads of sizes but have a look anyway because it’s only £109.99!

SDG I-Beam saddle and seatpost – £149.90 – £10.85

No, it’s not a dropper. Yes, it’s only available in 27.2mm size. BUT check out that discount. Crazy! Although it’s only available in 27.2mm you can buy shims to get it to fit whatever size seat tube your bike has. Why get this combo? It is incredibly lightweight and strong. The whole I-Beam system (using a clamped girder rather a pair of metal rails) was built with these factors in mind. Racers love I-Beam. Weight weenies love I-Beam. Maybe you’ll love I-Beam too?

This gram saving racehead combo can be yours for a measly £10.85!
