How to get ±5 mm Reach
Fine-tune your ride like never before
Do you want to make your bike longer for high-speed stability, or shorter for tighter control in technical terrain? With our Freakynuts Reach Adjust Headset (+/-5 mm), you can customize your bike’s reach—without changing your frame Cheometrics or stem. Here’s how to install it, step by step.
Why ±5 mm Makes a Big Difference
- +5 mm = longer reach = more stability at speed
- -5 mm = shorter reach = more agile, playful ride
Perfect for downhill, freeride, enduro or park setups.
Who Is This Reach Adjust Headset For?
Many of our customers choose this ±10 mm reach adjust headset because:
- They’ve outgrown their frame and want a bit more/Less room on their bike without buying a new bike
- Their current frame feels just a bit too long and needs a shorter reach for better control
- They’re setting up a youth bike where the rider is between sizes—like a kid between size S and M
- They want to experiment with reach before committing to a new frame or expensive stem combo
This makes it perfect for:
✅ Riders growing fast (especially teens)
✅ Riders between frame sizes
✅ Riders tweaking their bike for specific terrain
✅ Bike shops looking for a clever bike fit solution

Step-by-Step Installation Guide
1️⃣ Remove Your Old Headset
- Take out your old upper and lower headset cups
- Remove the crown race from the fork
- Clean the head tube thoroughly
- Make sure bearing seats are smooth and undamaged
2️⃣ Mark the Head Tube Centerline
- Use a straight edge or string to find the vertical center of the head tube
- Mark it with a fine tip marker—this will be your reference line in case your frame is not marked with a center point
3️⃣ Understand the Cup Offset
Each headset cup has an offset center:
- Align the slots on the cup with the head tube centerline for a neutral position
- Rotate the cup forward (thin side facing forward) for +5 mm reach
- Rotate it backward (thick side facing forward) for -5 mm reach
4️⃣ Install the Lower Cup
- Grease the outside of the cup
- Align it to your desired offset (+5 mm, -5 mm)
- Use a headset press or soft mallet to seat it evenly
- Double-check that the offset direction is correct before fully pressing it in
5️⃣ Install the Upper Cup
- Repeat the same process for the upper cup
- Make sure both cups are flush with the frame
- The offset between upper and lower cups can be combined if desired
6️⃣ Install Fork and Bearings
- Install the crown race on your fork
- Grease and insert the bearings into each cup
- Slide the fork into the frame
- Add compression ring, dust cap, and stem spacers
- Tighten the headset preload bolt until there’s no play, but smooth rotation
7️⃣ Test and Adjust
- Turn the handlebars to check for smooth movement
- Go for a short ride and test the new reach
Tips from the Trail
- +5 mm reach works great for stability in downhill and high-speed enduro
- -5 mm reach helps with technical switchbacks, dirt jumping, or park riding
- Combine with shorter or longer stems for even more tuning
