Expensive for what it it is but beautifully finished and definitely light

If you are going to go splashing out on Deda's snazzy Superleggera carbon bars you're going to want an equally impressive stem to hold them. As the name suggests, Deda would like you to consider the Superleggero stem, as they are designed as a partnership.

Deda claim this is the lightest production stem on the market. However, Ritchey's WCS C260° stem weighs 9g less than the Superleggero's still impressive 124g. The Superleggero is all about removing as much material as possible through design without compromising strength, Deda says.

Like a lot of stems the Superleggero is 3D forged from 7050 aluminium. Forging makes for a stronger structure than welding various parts together therefore allowing you to shed weight. The internals are pretty much hollow to so it's basically as light as it can be.

More weight is pared by using two individual strips of alloy for the face plate. You've got a little less surface area than a normal plate for clamping duties but it doesn't seem to make much difference. All the hardwear is titanium which knocks off another couple of grams.

In use the Superleggero is surprisingly stiff. I'm not light at 76kg yet no amount of manhandling the bars could get the Superleggero to flex noticeably. Climbing or sprinting was all taken in its stride and paired up with Superleggera carbon bars things were very comfortable.

The size options start at 80mm through to 140mm all with an 82° angle. As you'd expect they are for oversized bars. Deda calls the 1 1/4in handlebar diameter 31.7mm; everyone else calls in 31.8mm. If we were going to be picky we'd all call it 31.75mm. WHatever, it's all the same thing and bars marked 31.8mm will fit fine.

The Siperleggero is manufactured to accept a 1 1/8in steerer though you do get a 1in spacer sleeve included should you still be running around on a bit of old-school steel erotica. [We think Liam means 'exotica' but we're leaving it alone to show you just how some of our reviewers' minds work - Ed.]

The Deda Siperleggero stem is a bit of an extravagance at £116.99. A stem half the price will probably do near as damn it the same job, and the Ritchey mentioned above is just £75. In its defence though the Deda is beautifully crafted and has a really good feel to the finish but more importantly, when it's paired up with the matching carbon bars the two work really well together.

His fascination with gravel bikes is getting out of control too!

I run WCS 260’s on a couple of bikes and they are superb - but when building my C59 I thought I’d go all out and get this bit of Italian bling. There’s no doubting that it looks fantastic, especially the black on black version, but it has one flaw…the Ti bolts are made of cheese! A bolt on the first stem snapped and another rounded out, then two bolts on the replacement rounded out. They’ve now been swapped for steel bolts with no issues. NB - no need to pay £117. I picked mine up for £77.

And it matches the Super Record RS groupset perfectly. Hello final piece of the C60 build jigsaw.  1

in line with previous comments about Deda's cheaper offerings - The Zero2 stem is really well finished, about £25 and 16g heavier.

If I'd get a stem, I'd need a white one, with red graphics. Fortunately, Deda do those also.. But Kalloy Uno ultralights too. Would be glad to see a "comparison" between big-brand named stems with those "budget options".  39
