GrigioCarbonio MTB T1000 Cranks - BCD 104 mm - 255 gr.

With weights starting from just 255 grams (165 mm cranks, matte finish, chainring excluded) the GrigioCarbonio T1000 MTB are the lightest cranks for MTB use in the world (for XC, XCO, Marthon, All Mountain, Trail use)! This record is not an end in itself but the natural consequence of careful design and the use of the best materials and technologies on the market. GrigioCarbonio products are top of the range products made in Italy, characterized by high performance (stiffness/weight ratio at the top of the category) and great reliability with truly top level total quality.

The GrigioCarbonio T1000 MTB cranks are made entirely of Torayca T1000 fiber, one of the most performing intermediate modulus fibers, developed for the aerospace sector and capable of optimizing the strength/weight ratio to the maximum. Another important feature of T1000 fiber in the great elasticity (25% more than T800), so a final better impact resistance, less vibrations and a superior comfort...all this is really great for MTB cranks!

T1000 carbon fiber is at least 4 times more expensive than T700 and T800 carbon fiber (which are usually used to make carbon fiber cranks). GrigioCarbonio is proud to offer a top quality product with unique features at a competitive price, that's the real goal. 

If the materials used are very important, the way and the technology with which they are used is even more important. GrigioCarbonio MTB T1000 cranks are made with monolithic technology (monocoque) and are characterized by a "sandwich" structure with layers of twill type external bidirectional fabric that wrap a "core" in unidirectional UD fabric. The twill fabric is characterized by greater resistance to impacts and delamination while the unidirectional fabric allows you to make the most of the structural and mechanical properties of the fiber.

The left crank constitutes a single monolithic block with the axle (oversize diameter 30 mm), the spider on which the chainrings are mounted (BCD 104 mm 4 arms) is instead monolithic with right crank. The only aluminum parts are those that have threads, therefore the bushes onto which the pedals are screwed, the bush integrated into the axle onto which the right crank arm is screwed, the relative fixing screw and self-extracting ring nut and finally the preload ring nut which manages the side play of the bottom bracket bearings. All the "hardware" is generously sized with large safety margins.

The GrigioCarbonio T1000 MTB cranks are made in 4 different lengths (165 mm - 170 mm - 172.5 mm - 175 mm), the Q-Factor is 174 mm (the internal distance of the cranks is equal to mm), while the chain line is equal to 52 mm (optimized for the Boost standard).

The finish of the cranks is matte with the classic 12k T1000 texture used by GrigioCarbonio, UD and glossy finish can be chosen on demand. The glossy finish requires additional painting with a slight increase in weight and is less strong than matte, UD finish adds around 12-15 grams.

The graphics are adhesive decals, which can be customized on request in terms of livery, size and positioning. All the aluminum parts have a black anodized finish, on request they can be gold anodized (limited availability).

The GrigioCarbonio T1000 MTB cranks are equipped with an integrated 4-arm spider on which 4-hole chainrings with 104 mm BCD bolt circle that have at least 30 teeth can be mounted. The chainrings are not included with the cranks and must be purchased separately.

The GrigioCarbonio T1000 MTB cranks are compatible with different bottom bracket standards such as BSA, BB30, PF30, BBright or PressFit Shimano as long as they are equipped with bearings suitable for the 30 mm axle. The cranks are equipped with a practical preload ring nut for adjusting the lateral play of the bottom bracket bearings which allows you to optimize their smoothness and durability.

No bottom bracket is included with the cranks, so if you don't already have a suitable one, it must be purchased separately. Together with the cranks, GrigioCarbonio provides a kit of Delrin spacer rings of various thicknesses that allow installation with most bottom brackets on the market compatible with 30 mm axles. Upon request, for special cases, these spacer rings can also be made to measure.

The GrigioCarbonio MTB T1000 cranks, like all GrigioCarbonio products, do not have any maximum rider weight limit and are entirely made in Italy in an artisanal manner but with technologies that guarantee quality and absolute precision. The cranks are made through autoclave molding with composite material molds to guarantee maximum fibers compaction, containment of expansion and homogeneous distribution of the resin polymerization.

Thanks to a complex and detailed production process combined with obsessive attention to detail, it is possible to guarantee quality control worthy of an excellent product. In particular, great care was taken in measuring the axle diameter to ensure perfect coupling with the bottom bracket bearings and also the flatness of the crown, all with centesimal tolerances.

The GrigioCarbonio MTB T1000 cranks are the lightest in the world with weights starting from just 255 grams (165 mm length, matte finish) but despite this weight record they are very high performing and safe, thanks to the materials and technologies used but above all to the company's know-how and ability to optimize lightweight structures. The laboratory tests carried out provided truly satisfactory results both in absolute terms and in comparison with the competition.

The GrigioCarbonio MTB T1000 cranks are by far equipped with the best stiffness/weight ratio ever with superior resistance characteristics even to heavier high-end commercial products. And this is precisely why they have a reason to exist, that is, a special product that can be much more refined and superior to widely used industrial products.

With the cranks, Dream Bikes can offer combined chainrings and bottom brackets of high quality and low weight to maintain an absolute record setup! Check our webshop or contact us to check any compatibility with your MTB.

GrigioCarbonio's production capacity is limited and often lower than demand so waiting times can vary depending on the quantity of orders accumulated, contact us without obligation to get an updated estimate of waiting times. Since the products are procured to order, they are outside the canonical right of withdrawal and require advance payment (the cash on delivery payment method is therefore not accepted).
