At one end (nearest to the rider if sitting on the bike), the stem has a hole through it top to bottom, with pinch bolts to clamp it to your bike’s steerer tube. Here, the stem holds the steerer tube in place in the headset. The Paul Components Boxcar Stem (silver) is the perfect combination of stiffness, strength and reasonable weight and may be the coolest looking stem right now! Perhaps the main USP of the Burgtec Enduro MK3 is that it is available in a 42.5mm length. It may sound daft and all rather Princess-and-the-pea, but a couple of mm here and there with stems can certainly be felt by experienced riders. So if you’ve tried 40mm and 45mm stems and not quite gelled with them, here’s the (42.5mm length) stem for you! What we really like about the Race Face Turbine R35 is that it’s pretty stiff for a lightweight machined stem. Even with a matching 800mm Next R bar fitted, the steering feels precise and immediate, with just the right amount of resilience. On that note, you can also change your stem length to adjust the reach from the saddle to the handlebar.

The steering response with the Apex is very good and we found it feels solid on the bike. There’s a slight amount of torsional flex, especially when really wrenching on the bar, but on a stiff, carbon-framed e-MTB with carbon wheels, a little bit of flex is no bad thing as it improves ride feel. It's only when you stand over it, you know, when you physically stand over the bike, that then you say 'hey, I don't have much stand over height', you know"-T. Ellsworth As we’ve already touched upon, though, it’s also now common for high-end road bikes to come with an integrated, one-piece handlebar and stem. The main standards you’ll find for bike stems are summarised below. As ever, more exist – and some bikes, such as the Canyon Aeroad CFR, use a proprietary system – but this captures the majority of common options on the market. 1 1/8in steerer, 31.8mm bar clamp This stem was designed from the ground up to be stiff, strong and pretty darn light too. The rounded box shape is some 25% stiffer than the competition and after extensive real world and machine testing, proven this to be the best combination of these three principles as well as one damn strong stem!The Paul Comp Boxcar Stem is the perfect combination of stiffness, strength and reasonable weight and may be the coolest looking stem right now! Stems are either 3D forged or CNC machined from an aluminium billet (basically a chunk of metal). Forging sees aluminium squeezed under immense pressures into (close to) the stem’s final shape. The technique compresses the material around high stress areas, and it’s argued produces a stiffer product with a better-aligned, denser grain structure. The initial forging cost is expensive and the finish is sometimes less angular, although you do see stems that are forged initially and then tidied up on a CNC machine. Personally I have 3 three stems and two bars that I will swap out. My default is a 0 degree rise 60mm stem on a flat 720mm bar, I will swap in a -17 stem for big pedalling days. For more aggressive riding I have a 50mm stem on a small rise 740mm width bar. These swaps change the feel of the bike dramatically and even require a bit of suspension tuning to rebalance the bike. With a rainbow palette of anodised colours, the Race Face Turbine R stem indulges your creative side. Whether you choose to go mild or wild, the sturdy forged and CNC’d body is stiff enough for the widest of bars and burliest of builds and even comes in a stubby 32mm length if you’re looking for a truly direct steering response. The gapless clamp holds bars securely and spreads loads evenly, while the rounded-off edges of the steerer clamp keep the opposing bolts away from your knees. The length of your stem can have a significant impact on the fit and handling of your bike. There’s also usually a slight angle between the steerer tube clamp and the long axis of the stem. We’ll explain the significance of both later.

Found on some mountain bikes and also some drop-bar machines such as Giant’s cyclocross bikes. 1 1/8in steerer, 35mm bar clamp This unique bar and stem combo uses an incredibly simple idea to create our favorite defibrillator for bikes with dead handling. First instinct is as YW says above - the frame is too big. Putting the saddle so far forward will affect your pedaling too - part of the bike fit should have included fore/aft saddle position. That's because it's the rake and the trail which actually makes a bike sharp or slow to steer, not the stem, though you'll certainly notice the difference between a very short or a very long stem. Yeah you're right chaps the winter big has a way too long top tube, I think the combination of age and injuries has made it more noticeable, it used to be fine (like most people it's my old good bike, a giant tcr)Bike stems connect the handlebars to the steering tube of the bike frame. Getting the right stem is essential for customising height and ensuring you feel comfortable on your bike. The height of your handlebars is one of the components that dictates your stance in the saddle, whether you’re more upright or seating more forward. Road Bike Stems Ensuring the top cap is in place, tighten the bolt until you feel some resistance. This top-cap bolt is used to pre-load the headset bearings. Jem McPartlin Mountain bike stems are typically around 50-80mm long, while road bike stems are longer, starting at around 80mm and extending to 120mm or longer as the frame size increases. Gravel bike stems typically sit somewhere between the two. Newer gravel bikes typically have stems that are a bit shorter than those found on road bikes, usually 90mm or less.
