Chris King Headset, Mango

Chris King GripNut™

Maybe I overtightened the original headset on my Brompton. I had some play and after fixing it, the added force maybe caused premature wear to the bearings. It is easy to overtighten the headset – this is a job that needs experience, a “feel” for the right torque – but a non pro mechanic has to adjust a headset only once in a year – max – nothing to build up the needed sensitivity.

Anyhow. I had a reason to get a new headset and since I love Chris King headsets (I run one on my Moulton too): that was the place to look for a new one.

My new wall mount stand

Expensive (around 200 €), but a perfect solution… from Park Tools – called PRS-4W-2.

The wall mounting plate is 15cm x 6cm and fixed with two mounting bolts. The stand uses what Park Tools calls “the 100-3D Micro-Adjustable clamp”. This clamp allows adjusting the clamping pressure in a very sensitive manner. I use the seat post of my Brompton to mount it.

The stand is a rock steady solution – quick entry and no legs to run over. I like it a lot.

6-speed gear ranges and ratios

My orange Brompton came with the standard 6-speed option. Here are my thoughts about the change to a -12% setup.


That’s my Pedersen bike – I owned it for more then 15 years and sold it lately. I liked the look of the Pedersen a lot, but cycling on the bike never got me.

DIY: Garmin Edge 305 on a Moulton AM

I faced massive problems when I tried to mount a wireless computer on my Moulton. The distance between the handle bar and the front tire is too big – too big for most solutions from Cateye, VDO or Polar.
