Could you please post a link to Quick action stem clamp bolts ? I can find seat fittings but not a fitting to replace the twin allen key bolts on my stem.

They're in post #3 above.

Those quick action clamp bolts have very many other uses. When you park your bike in a bike rack, you can turn the bars to make more room for others and get your bike in and out more easily when there are overlaps. When you lo k your bike to a tree or lampost, it makes more room for pedestrians. It makes a good anti-theft device, especially if you leave the clamps unlocked. A potential thief probably wouldn't be able to figure out why they can't steer, so they'd probably abandon it straight away. If you left the bars flat, they might assume that they need tools to straighten them to ride it. Every little helps.

I've seen a video of a thief trying to steel a bike off a rack from a car in London while the car was driving. He was following on a cheapo bike, and every time the car stopped at traffic lights he undid more of the clamps and straps. His planwas probably to abandon his bike and ride away on the valuable stolen one. With bars clamped flat, he would know that he couldn't ride it, so wouldn't have bothered.

The quick action screws on the step allow you to turn the bars into the same plane as the wheel.

what's wrong with using a Y-shape Hex key 4/5/6 mm?

I couldn’t find any suitable for twin Allen bolts on our Wisper bikes at all. Leaving that option at present.

The exact ones in the link would probably be OK. What size are your screws?

Nothing I guess other than convenience ? I am forever changing my saddle height (for dull reasons ) so go with a quick release . I could use Allen keys but when you do something all the time then qr is faster and doesn't need tools

Having said that I also find I am super sensitive to how exactly central my stem is. Tiniest nano mm out of central and I feel it badly in my arms generally (well one of them) and steering on off road descents especially . So QR stem bolts as a concept gives me shivers !

Hmmm! Mine is quicker to install, quicker to operate and cost me about £3. Why would anyone want to buy that one for £90??? Some people must be nuts.

yours does not look expensive.
SW will never buy it.
