This Gusset S2 31.8mm cockpit combo is great for those occasions that require a higher rise set of bars or an even shorter stem.

In a way, these two items are both at the extreme of things. The Gusset S2 31.8mm x 50mm rise handlebars are pretty much as risey as you can get these days (I think Spank and Answer make even higher rise bars?). You can get the bars is loads of rise options: 10, 20, 30, 40 and this 50mm. The 30mm stem is literally as short as you can get without going down the Pacenti P-Dent route.
The stem is yet another argument for staying/returning to the 31.8mm standard (the other argument being that 35mm cockpits are overly harsh feeling). You can’t make a 35mm clamp stem as short as this. 32mm is as short as you can get for the 35mm clamps.
It’s mainly this super short stem that is of most interest and exhibit the most influence on bike handling.
Let’s get the handlebar review out of the way first then.
The numbers speak for themselves. The 5° upsweep and 8° backsweep felt fine. Not weird. Neutral. The 780mm width is borderline for some wider-is-righter riders but I was fine with it. The shot-peened stem clamping area is generous and mates well with its stem sibling.
The ends of the bars, where the grips sit, are also shot-peened. I kinda wish they weren’t. I prefer to run push-on grips and shot-peening surfaces are what tend to allow water ingress resulting in spinning grips. I wish Gusset had just left the bar gloss finished all the way to the ends. Ah well. Most folks run lock-on grips I guess.
(You may be able to see the scratty ends of some parcel tape in some of the photographs in this review. Applying a single layer of parcel tape to the ends of bars is how I stop my push-on grips from water ingress-induced spinning.)
The bars are made from 7075 aluminium. They have cut markings. The bars have been custom butted and swaged, apparently. Whatever. They offer a very pleasant ride feel. And in this 50mm rise version are really useful for curing any test bikes that come with low front ends (especially those that have had their fork steerers cut to within an inch of its life).
All-in-all, good to have another 50mm rise handlebar option in The Best Standard (31.8mm). Price is good too. Well done Gusset gang.
On to the rinky-dink stem then.
Numbers time. This is the 30mm long one. Also available in 40 and 50mm length. Zero rise. Fair-to-middling 42mm stack height. CNC machined form 7075 aluminium.
It’s a ‘zero gap’ design (the faceplate fits with a zero gap on the upper bolts). I like zero gap stems. Easier to tighten properly (bars fit precisely with equal torque).
Most modern short-stemmers out there are probably riding around on 35mm (in every sense) stems. If you’re reading this review, this is quite possibly your setup. So, the $64,000 question here is, “is it worth going 5mm shorter?”
The answer is… Maybe. Depends. Probably not. Definitely.
I’ll elaborate.
If your bike has a long enough reach to it, by all means slap a 30mm stem on there. Especially if your bike’s head angle is the righteous side of 65° (ie. slacker than). There are no down sides to short stems, so long as the other important geometry numbers are in place.
If you’re already feeling a bit shy of reach and/or twitchy of head angle, I’d probably not go to a 30mm stem.
Unless…
Unless your bike is an e-bike.
Even on e-bikes that aren’t exactly generous on reach can benefit from such a super short stem. Why? Gosh, I’ll do my best to explain in as unconfusing a way as possible.
Basically, more of your intended inputs go into the tyre/ground contact patch instead of going into jackknifing the cockpit.
Less basically – and for example – when you want to load-up the left side of your front tyre to increase its traction (whether off-camber and/or turning left), the action of pushing down on the lefthand grip and pulling up on the righthand grip generates – with this sten – the desired force into your wheel. There’s less deflection or understeer.
I specifically mention e-bikes in this regard because of their extra weight and momentum. Lighter non-E bikes take much less Body English and the understeer is far less of an issue.
The sheer shortness also has (in my opinion) a beneficial impact on the general responsiveness and nimbleness of the whole bike when it comes to e-bikes, especially full-fat big-battery e-bikes.
In many ways, going to 30mm (from 35mm) feels like going to 35mm (from 50mm). If there’s one place where a handful of mm can be felt significantly – and instantly – it’s stem length.
As mentioned earlier, the only stem system that’s shorter is the Pacenti P-Dent system. Which are great and everything but, for me, the bars don’t come in high enough rise options and the general feel of Pacenti P-Dent bars is incredibly stiff and harsh. So, 30mm is the shortest option we have currently if we want high rise bars and/or a comfy ride feel.
Overall
A pair of well made and decently priced items that are well worth knowing about. They may not be utterly essential for everyone but for those occasions that require a higher rise set of bars or an even shorter stem, the Gusset S2 31.8mm combo have a permanent place in my componentry collection.
