The home-mechanic’s dream tool, the Giustaforza II has a smaller, non-ratcheting head than the Pro, to operate in tight spaces. The DELUXE version is completed with cycling-specific bits and comes into a practical wrap package.Capacity from 2 up to 16 Nm: This is the best torque range for precision bicycle applications and ‘sensitive’ components. In use, always refer to the torque values specified on technical documents or printed on the parts themselves.Easy to use:Set the desired torque rotating the wrench end knob, reading the torque value on the scale (scale resolution is 0,5 Nm, integers on one side, 0,5 on the other). Insert the appropriate bit (depending on the bolt you need to tighten). When using the tool, a loud ‘CLICK’ and a 3° free-movement tells when the torque has been reached. Always take the wrench to minimum torque value after use.Minimal fixed head:Giustaforza’s simple, ‘non-ratcheting’ head has been chosen on purpose on this version, to facilitate the tightening of bolts where space is very limited (like seatpost bolts parallel to the seatpost shaft in zero offset models). The head is now smaller than ever, to maximise this advantage.Lightweight:The light aluminium body keeps the weight down to a record-breaking sub-180g value, less than half the weight of other torque wrenches in this range of torque. This is paramount to get the right feedback at low torque values, without mistaking the effort to hold the tool with the applied torque.A state-of-the art tool, built to last:Functional, linear in design and precise in any detail: shouldn’t be a surprise to know that Giustaforza II 2-16 has been conceived and produced in Italy. The tool is hard-anodized with laser-etched inscriptions, and it’s built to last. The mechanical, click-type functioning make the wrench extremely shock tolerant and the absence of batteries or electronics further increase its reliability. Each sample is checked and numbered as a single masterpiece.Controlled torque:The DELUXE version is equipped with a bicycle-specific bit set:bits include a 100 mm-long extension, three 100 mm-long bits (hex 4, hex 5 e T25) plus several other Torx and hex bits in standard length (25 mm). That covers all the needs of newest Shimano, Sram and Campagnolo high-end groupsets, plus those of reversed-bolt stems.All bits are manufactured from S2 special steel, with very high (62 Hrc) surface hardness, to ensure maximum durability.Detail of bits:10x25mm (HEX2, HEX2.5, HEX3, HEX6, T10, T15, T20, T30, -3/16, +PH1)3x100mm (HEX4, HEX5, T25)1x100mm (extension)
The long-sleeve Gabba is one of our most versatile pieces. 100% wind protection with GORE-TEX INFINIUM™ WINDSTOPPER® water protection and best-in-class breathability. With a light base layer it's good for mild temperatures, or with a thermal layer you can ride it below freezing. If you have just one jacket in your cycling wardrobe, this should be it. Sublimation print graphic on the do-everything Perfetto RoS 2 Jacket base Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water-resistant fabric on front-facing surfaces GORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for greater stretch and breathability Taped shoulder seams for extra rain protection Top- and bottom-opening YKK® Vislon® zipper for easy sliding, covered for additional wind and rain protection Zippered ventilation opening on side of chest 3 rear pockets Reflective panel at bottom of pockets. The Unlimited version of the Perfetto RoS 2 Jacket is simply a graphic treatment making it look more at home on any surface but not sacrificing any of the performance. When we think about what we want in a gravel jacket, we keep coming back to the Perfetto, since it really is perfect for so many conditions. We just want it to look different. The Perfetto RoS 2 excels in dry conditions thanks to the high breathability, as well as in wet conditions thanks to the Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabrics. There's a light fleece-lined water-resistant fabric on the forward-facing surfaces and a lighter and stretchier fabric on the back that maximizes breathability while providing excellent water repellency. The Perfetto RoS 2 Jacket keeps all the cold wind out while being much more breathable than the typical polyurethane membranes used on most jackets that try to compete with the Perfetto. When you stay drier you don't need as many layers underneath. The beauty of this jacket is that it doesn't have any insulation on its own, so a thin base layer is just right for mild conditions, while adding an insulating layer (a thermal jersey or Castelli's Alpha 2nd Layer) will take you to cold temperatures. You decide. The 2 part of the name refers to the updates to the latest version, including a YKK® Vislon® zipper with both top and bottom openings for more adjustable ventilation. The reflectivity on the back is more visible, the seam at the top of the shoulder has been moved to the back, and the three pockets hold more gear. While the Perfetto remains decidedly a performance fit, the new model has a touch more room through the chest, shoulder, and biceps. This is the one jacket that belongs in every cyclist's quiver.

Whether you're touring across the city or planning your next drop bar gravel bike adventure, this suspension seatpost is engineered for smooth and dependable performance. It features a hard-wearing forged aluminium build, which gives it excellent toughness when travelling across mixed terrain conditions. Suitable for a wide range of riding disciplines, this model is also compatible with electric bikes (E-bikes). Bolt-On Comfort For over 20 years, Thudbuster has been the bicycle industry-standard in suspension seatposts by providing unequalled comfort and reliability to riders around the world. Suspension Seatpost The latest generation Thudbuster LT is superior to its predecessor in every way. Building on Thudbuster’s proven parallel linkage technology we have completely re-designed the seatpost for increased durability, additional suspension travel, as well as ease of use through tool-free elastomer change and a single-bolt seat clamp design. By improving on this already legendary design, we’re confident to say that the newest generation Thudbuster is the most advanced suspension seatpost ever made. Parallel Linkage Design The Thudbuster Parallel Linkage technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and forward into the rider. The Thudbuster works by compressing along the exact opposite path — down and rearward — absorbing force at the same rate. This results in a natural suspension feel without being overly active and allows for more travel without compromising pedalling position.
