Pinhead PH111 Quick Release Wheel/Seatpost Lock 3 Pack Bicycle Set, Black

Feel much better having these on both my wheels and seat post. Having my chain/D-lock alone on the bike and knowing they can be cut off made me feel less confident about any of my bike parts being stolen, but I know with these they can't quick release anything off, and Alan keys etc won't work either. Great product!

A great product but you should be able to get the full set on the same key without needing to mail order , ie headset lock and seat lock that are notably absent in this set but can be bought separate. The sets are there but only if you want to pay for a chain lock too, however it's a good product none the less.

These are easy to install and not *too* fiddly (though the key doesn't actually provide that good a grip on the bolt heads, in my experience). However, they wouldn't deter a determined thief who has time with your bike. If I lost the key, it would be annoying but not that hard to remove these bolts with a pair of pliers, as the holes where the pins grip are handily on opposite sides of the bolt head. A straight line drawn between them doesn't go directly through the geometric centre of the bolt, but it's close enough to make pliers a fairly easy workaround if you don't have the key.So... yes they are clearly a better deterrent than a hex bolt or allen key bolt (and miles better than a quick-release tab, obviously). But you're not really buying proper security here, you're buying obscurity - banking on a thief not bringing a simple set of small-nosed pliers or deciding some other bike nearby is a better target (do you always lock your bike next to loads of less secure ones?). I regret not just buying a cheaper set that uses a similarly obscure bolt head without the nice branding.That said... they do work, they are of high quality manufacture, they are easy to install.

Contains front and rear locking skewers plus one for a seat post. Parts are well made. Key fits nuts nicely and, unlike earlier models, grips them firmly while applying pressure in either direction, Comes with extra skewer washers if required. Key has a code on it that can be registered with Pinhead in case you loose it. The locking design is good, with nowhere for tools to get hold of an edge for turning - unlike other brands. This will likely put off most thieves; however, they are not 100% secure if a determined thief is given plenty of time alone with the bike. Leaving your bike locked somewhere very public should help.

Front post lock does not fit earlier Kalkhoff bikes

Once fitted You don,t have to lock your wheels any more

Very good thanks

Kind of very cool idea and minimalist look when installed, but the handle is quite small and lining the tool up prior to locking or unlocking without slipping (you don't want to damage the faces) is not so easy and definitely takes a good while longer compared to a QR, because you cannot spin it up in one go!!! Once all tight it's fine, but if you regularly need to take off wheels eg to put bike in the car it's a pain cos it takes much longer. You also must remember to take the remote handle with you to make adjustments eg to ride height. If you don't need to remove 🛞's i give it 4 ⭐. If you do then just 3.
