Troy Lee Designs - D4 Carbon Optic MIPS Helmet (MTB)

D4 Carbon Optic MIPS Helmet is a Troy Lee Designs mountain bike helmet built for mountain bikers who want full-time confidence. The D4 platform is known for downhill-focused coverage and a locked-in feel when the terrain gets steep and fast. Carbon construction points to a lighter, more premium feel that works well for riders chasing high-end performance. The Optic graphic gives it a distinct finish that stands out in the pits, on the trailhead rack, or in the garage. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

It is shaped for modern off-road mountain biking, with the secure feel, airflow, and coverage riders look for when the route mixes climbing, descending, and repeated hits through rough sections.

Why We Like It: it fits the way a modern MTB helmet should: secure, ventilated, and ready for real terrain.

Why It’ll Work for You: It is easy to match to the rest of your kit and easy to live with between rides, which is exactly what most riders want from an MTB helmet.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.

Excellent Tool For Drilling Shelf Pin Holes
I had a project where I was extending the depth of the bottom half of a bookcase I had made out of pre-drilled MDF from Home Depot. The original bookcase was 11" deep x 10' high. The extended depth of the bottom is to be used to hold audio gear and needed to be 18" depth, front to rear. I was able to increase the depth but had to insert additional panels on the left and right so that shelf pins could be installed. I needed a shelf pin jig to do that, and this jig was perfect for the job. After completing my holes and mounting some shelves I was pleased that the alignment with the inner portion of the shelf was perfect and the distance between holes lined up exactly as with the original panels from Home Depot. The jig is high quality fabricated aluminum, not plastic, and it comes with two drill bits, and stop and Allen wrench, including an instruction manual, all in an attractive plastic case. The jig is well worth the modest price and I would definitely recommend it for drilling shelf clip holes.

a solid choice
I realized I don't need to drill 5mm holes, so this item is just perfect. It's higher quality than those other cheap-chinese noname jigs. In particular: * The stop collar provided actually fits the drill bit. I had one from Tanyo that had too-big collars that didn't stay put. * The fence pins are very soilid, so the jig doesn't move while in place. Other brands have a long knurled screw that wobbles and allows the kiig to move around. * The plate is thick, making it feel sturdy. * It's phyically smaller than the others, because it doesn't have any useless features like euro-hinge hole guides. The case is more compact and stores well. Overall, very satisfied with this jig.

A solid and easy to use product.
Worked like a charm. It is extremely durable and easy to use. I bought this item because the one I wanted wasn’t available. I don’t regret getting it.

very nice tool
likes, all aluminum construction, seems very accurate and uses more sturdy 1/4 inch shelf pins instead of the 5mm ones comes with 2 bits which is a huge plus the competition makes you buy the 1/4 drill and only is set up for 5mm to start. this jig will work along side, for now, my other jig dislike is the fact it only has 1/4 pin capability not a deal killer in any way, and it has "pins" to support the jig on the edge again this is both an advantage and disadvantage as you can change the depth of where the pins are located BUT if you are making something smaller the jig may not calibrate consistently. on another positive you can replace the bits easily and commonly as they are not proprietary and simply standard 1/4 inch bits this will be a fine addition to my other goingmake tools and future ones
