I’d like to show you one of those customizations that people often forget about.
That would be the seatpost clamps.
You can go matchy matchy with the headsets, or you could simply put a random color to give the bike some nonchalant steez.
DKG, PHIL WOOD, and more recently, even CHRIS KING have joined the lineup, along with our beloved THOMSON. There are actually quite a few options out there, which is definitely a good thing.
Today, we’re going to walk you through how to replace your seat clamp.
1. Measure your current saddle height.
Alternatively, use your current saddle height as a reference by marking the position on the seatpost with masking tape or something similar. This way, you can easily replicate the same height after replacing the seatpost.
2. Loosen your current seat clamp.
Use the appropriate Allen key for your seat clamp. Keep in mind that the required Allen key size can vary depending on the model.
For reference: PHIL WOOD, DKG, and SURLY stock clamps use 5mm; CHRIS KING and BLACK MOUNTAIN stock clamps use 4mm; and THOMSON uses 3mm.
3. Remove the seat clamp and measure the outside diameter of the seat tube.
Once you have the measurement, choose the appropriate seat clamp size.
In my case, the seat tube on my BLACK MOUNTAIN Monster Cross measured 30.0mm, so the corresponding size from THOMSON is 29.8mm.
There is a 0.2mm difference, but don’t worry—this is intentional and accounts for manufacturing tolerances in the product design.
4. Click.
And that’s it. Simply reinstall the seatpost to the height you marked earlier, and you’re done.
Basically, all you need is an Allen key to do this yourself, so give it a shot!
