With weigths starting from only 89 grams , Darimo Carbon T1 Aero Evo Colnago Y1RS is the lightest seatpost in the world compatible with Colnago Y1RS frames. It's made in Spain with high quality standard and materials. It's compatible with road racing use and also gravel and cross use.
It's produced in straight version with +7.5 mm mm offset and setback version with -7.5 mm offset, with a 2 bolts clamping system. It's compatible with round (7 x 7 mm) and oval (7 x 9 mm) rail saddles both also carbon fiber made. It has got a wide ratio of tuning and it's compatible also with modern geometry frames.
Darimo Carbon T1 Aero Evo Colnago Y1RS seatpost is available in 200-210-220-230-240-250-260-270-280-290 mm length. The carbon tube structure of the Evo version is designed to optimize weight; it therefore features specific reinforcements in the area where the seatpost clamp tightens, resulting in a limited operating range (indicated on the back of the tube by two white lines):
Since the clamping zone is only 35 mm long, choosing the correct size is crucial; to do this, you must measure the portion of the seatpost out of the frame using your original setup (the original seatpost and the saddle you intend to use with the new Darimo seatpost). The reference measurement is indicated by the letter "X" in the image below; it should be measured along the seatpost's centerline, starting from the point where the seatpost exits the frame (not where it emerges from the dust seal) up to the surface where the saddle rails rest on the seatpost cradle.
To select the correct length, simply add 110 mm to the "X" value (for example, if "X" is 150 mm, choose a seatpost with a length of 260 mm). By selecting the length based on these parameters, the seatpost can still be lowered by approximately 20 mm and raised by approximately 15 mm. Please note: on smaller frames, it may still be necessary to shorten the seatpost to ensure it remains within the correct clamping range (this is because smaller frames allow for less seatpost insertion). Shortening the seatpost is a simple task that can be performed by any bicycle mechanic or anyone with basic manual skills.
The main tube is made of carbon fiber using bidirectional and unidirectional fabrics with an studied asymmetrical laminate to achieve the optimum combination of minimum weight and maximum of resistance. Each seatpost is laminated by hand to achieve a record weight keeping in mind the strength and your safety. To do this, at each point of the seatpost there are a different numbers and arrangements of carbon fiber layers. The layers arrangement is obtained after finite elements analysis and destructive testing.
Seatpost yokes are made of 7075T6 aluminum CNC machined to achieve smooth edges suitable for any type of rails, carbon rails included. seatpost cradle is made of carbon fiber and it's optimized to allow the best seating for the saddle rails.
The bolts has got M5 diameter and are grade 5 high quality titanium made with forged head and rolled threads. Black anodized color finishing. The front bolt has got a special design head with through holes which allows micro-tuning if required when there isn't enough room to use an hex wrench. The bolts are screwed up onto 7075T6 aluminium nuts. The rounded shape of this nuts allow a correct load distribution without local stressed points.
With weigths starting from only 89 grams, Darimo Carbon T1 Aero Evo Colnago Y1RS is the lightest setapost in the world compatible with Colnago Y1RSÂ frames! +/- 3% tolerance, UD finishing adds about 4 grams.
Here are some real weights from our scale :
- -7.5 mm offset - 220 mm - UD matte - 94 gr.
- -7.5 mm offset - 260 mm - UD matte - 97.7 gr.
- -7.5 mm offset - 260 mm - 3K matte - 96.4 gr.
- -7.5 mm offset - 270 mm - UD matte - 99 gr.
- +7.5 mm offset - 250 mm - UD matte - 101 gr.
Lightweight but also absolute safe, Darimo Carbon T1 Aero Evo Colnago Y1RS seatpost was designed with the help of modern CAD software and FEM analysis and easily pass the standard ISO 4210 tests! The maximum rider weight limit allowed is 95 kg, but on demand a custom seatpost for heavier bikers could be produced (consider about +10-15 grams added).
We recommend to install Darimo Carbon T1 Aero Evo Colnago Y1RS seatpost with the help of a good quality torque wrench following user manual specs (6 Nm max for seatclamp and 4 Nm max for seatpost yokes bolts). It's also very important to verify correct frame preparation to avoid any sharp edges (please follow user manual instructions, you can find the user manual inside the seatpost package and also inside the "download" section).
Seatpost tube can be produced with carbon fiber 3k twill or UD unidirectional fibers final layer with matte or glossy finishing, the cradle is always 3k twill (matte or glossy, matching the tube finishing), seatpost yokes and bolts are black anodized.
Decals are sticker type, 3k twill seatposts usually comes with white "Darimo" written and red Darimo logo, UD finishing seatposts usually comes with all black Darimo written and logo for a "stealth" look. Custom color decals are possible on demand. Please use the order notes to let us know your choice or write us by e-mail.
Darimo Carbon T1 Aero Evo Colnago Y1RS seatpost comes with a package which contains also user manual (English language) and installation pack with sand paper and carbon fiber mounting compound. There's also a label to certify product real weight. Any saddles present in the photographs of this product sheet are to be considered for purely illustrative purposes and are naturally not included with the purchase of the seatpost.
Darimo Carbon products are handmade and custom made with many sizes, finishing and lamination. The number of possible combination is very high so usually Darimo Carbon do not stock them and produce on demand.                        Â
Products that are available in our warehouse has got "IN STOCK" indication. All other products combinations has to be ordered from Darimo with waiting times indicated below the "add to cart" button. Please take note that these are indicative and may undergo variations
