Handlebar

Sonder Aspect Riser 780mm
Sonder Aspect Riser [OEM]
In general riser bars tend to be wider than flat bars and may have slightly more flex to give a more forgiving ride. As you go into descents and your arms drop below your knees the additional height gained on your front end will help you take control of the steep descents.

That said you can get all bar types in a range of widths and stiffnesses and front end height can be adjusted with spacers like our Sonder Rings, so sometimes you just have to ignore the mumbojumbo and make your call on style and personal preference and there is nothing wrong with that.
Sonder Aspect Flat 720mm
+€0
Sonder Aspect Flat [OEM]
Flat bars help you keep the front end of your bike low, allowing you to get the weight over your front wheel when climbing and giving you more control in cornering.

Our flats have a 5˚ rise so technically we should call them flatish, but if you really need them to be totally flat just rotate in the stem clamp!
Sonder Confucius
+€34,99
Sonder Confucius
Confucius says that you don't have to sacrifice what you love about your traditional riser bars just to get the flexibility of a hooped bar.

We have taken our Aspect risers and evolved them in to a bar designed primarily for bikepacking. You won't have to adapt to a new hand position so you are not going to lose any control off-road and you can still get out of your saddle and power up the hills like a hero.

If you do want to move your hands a bit a reduce the fatigue of a long ride, the hoop extends out front giving a choice of further hand positions. The bars also have a slight 'back sweep' so you can sit more upright in the saddle

The bars have a slight riser but feel free to experiment and rotate them to your suiting. Keep them horizontal, or twist them up slightly to give yourself a streamlined TT style riding position to help you battle across a windblown Tierra del Fuego.

Strength is not compromised as the main load bearing section of the bar is a single piece. Got gadgets? Confucius loves gadgets, and with the out-front hoop you can free up the bar around the stem. Simply attach your Garmin, 3000 lumen torches or mascots to the hoop and they will still be well within reach, maybe at an even better viewing angle and sit above your handle bar luggage.

Take your bikepacking into the mountains; Confucius is a bar that gives you more control than a tradional swept back bar on technical terrain.

Wheels

Sonder Nova 27.5+ Wheelset Shimano
Sonder Nova 27.5+ [OEM] Wheelset
Whether you're navigating rock gardens or tackling steep climbs, Novas will consistently give you a boost when the roads are rough and the terrain is tricky. Machine built for precision on Sonder’s sealed hubs.

Our design team’s expertise along with the factories we use mean that we can accelerate trickle-down technology to this price point.

Boost: wider, stiffer, tougher

Nova's boost hub is wider than a standard hub; extra width between the flanges promotes a shallower spoke bracing angle to create a stronger, stiffer wheel. A wider hub also means a shorter chainstay, more mud clearance, and better tyre clearance.

Wider rims mean tyres work better

38mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.6" - 3" tyres, which will plump up really nicely to give a broad contact patch for maximum traction and confidence.

Built to take abuse

Novas have sealed bearings that are easily serviceable without the need for specialist tools. Plain-gauge spokes have been chosen to keep the wheels super-strong, whether you’re landing big drops or loading your bike with luggage. And a steel free-hub body will take years of abuse. You could go round the world on these wheels.
Sonder Alpha 27.5 HG
+€169,99
Sonder Alpha 27.5 [OEM]
Alphas are our performance 27.5" wheelset for big hits and big tyres. Whether you're riding down Top Chief at Fort William or riding the black routes at Bike Park Wales, Alphas will consistently spin up to speed and keep rolling to help you ride with fluid precision over the trails.

Our design team’s expertise along with the factories we use mean that we can accelerate trickle-down technology to this price point.

Alpha hubs: wider, stiffer, tougher, faster

Alpha’s boost hub is wider than a standard hub; extra width between the flanges promotes a shallower spoke bracing angle to create a stronger, stiffer wheel. A wider hub also means a shorter chainstay, more mud clearance, and better tyre clearance. To make them faster we’ve used a 6 pawl freehub, which gives 120 points of engagement for immediate response when you turn the pedals (most hubs only have 60, which means you have to turn the pedals further before engaging the freehub). Oh, and the hubs sound amazing! Finally, sealed cartridge bearings just keep rolling and rolling.

Wider rims mean tyres work better

35mm lightweight aluminium rims make this wheelset ideal for rock gardens and technical terrain – you can run 2.4" - 3" tyres, which will plump up really nicely to give a broad contact patch for maximum traction and confidence.

Built to take abuse

Alphas have sealed bearings that are easily serviceable without the need for specialist tools. Double-butted spokes have been chosen to keep the wheels super-strong, whether you’re landing big drops or loading your bike with luggage. And a 17mm alloy axle make these hubs super-stiff and super-strong. You could race round the world on these wheels. Silk Road Mountain Race here we come!

Sonder Reko
+€59,99
Sonder Reko
The Reko are lightweight SPD pedals designed gravel riding and cross-country mountain biking over longer distances.

The Reko's platform-free design reduces the overall weight of the pedals to 145g per pedal for lighter, faster riding. Double-sided SPD bindings are easy to clip in and out of and their compact design means they're less likely to clog with muck on filthy winter rides.

The clip-in design improves the efficiency of your pedal strokes, saving energy on long rides and improving power transfer on climbs, and gives you more control of the back end of the bike.
Sonder Slingshot Black
+€74,99
Sonder Slingshot
The wide platform Slingshot pedal is designed to provide the support, control and confidence you need for a variety of riding, whether on trail, gravel or road.

Wide 87x90 platform made from 6061 aluminium

Double-sided adjustable SPD clips

Chromoly axle with sealed bearings

The Slingshot's wide foot platform provides plenty of support to the foot for more comfortable pedalling over long distances, reducing hot-spots. This additional foot support also gives you greater control of the rear end of the bike on tight turns or technical trail.

If you're using the Slingshot for mountain biking, the pedal's wide surface gives you a platform to stand on unclipped, ready to bail out if needed, on heart rate-quickening sketchy sections.

With double-sided SPD clips and a large pedal area, the Slingshot is easy to clip in and out of in a hurry. A clipless system provides greater pedalling efficiency when climbing and more control when descending.
Sonder Contact
+€49,99
Sonder Contact
The Contact are lightweight SPD-SL compatible pedals with a large contact area for energy efficient road riding.

The Contacts have a large, stiff platform, improving power transfer for sprints and climbs and supporting your feet for all-day spinning in comfort.

The bigger contact area of the SPD-SL system is more energy efficient too, preserving your legs for those deceptively savage inclines at the end of your ride.

The thermoplastic body and fibre-glass-reinforced binding keep the weight down to 148g per pedal, shaving vital grams from your drive chain.

Sonder Sideblade
The Sideblade bottle cage not only gives your water bottle a lovely, secure hug, but its side loading system makes it easier to access when you need a drink, making staying hydrated a joy even when you've got a load of frame bags to work around!

The Side blade is geared at letting you get to your water when you've got a bike packed up with frame bags, this means that it's also ideal for compact and full-sus frames where a standard loading bottle cage system just won't fit, you can choose which side you'd like to access your bottle by with a twist of the cage in the mount before your ride.

Made of polycarbonate, the Sideblade is also super light and super duper tough - hooray!

The Sonder Front Fender protects you from excessive mud splatter on wet, mucky trails. These lightweight plastic mudguards don’t require any special fixings on your bike and can be strapped straight onto your forks with 4 cable ties (supplied).

Made from durable polypropylene, if the Fender does meet its end, it can be easily recycled by most councils or at your local recycling centres.
Saddle

Sonder Zone 133 / Black
Sonder Zone [OEM]
The Zone is designed for maximum pedalling efficiency and comfort on longer rides, whether on road or off it.

Chromoly rails with suspension system

Cut-out shape relieves pressure

High density foam seat for comfort

We’ve selected a flat saddle profile that’s long enough to allow for lots of micro-adjustments to your riding position over the course of a full day on the bike. The nose width allows you to move forward over the pedals on climbs and sprints, and a tapered back enables you to get behind the saddle easily for switchback descents or technical off-road sections.

We’ve chosen a nylon fibre saddle base to provide a stiff and stable pedalling platform for a low overall weight. This base is connected to the chromoly rails using a patented suspension system that reduces road buzz and improves comfort without compromising on support.

High density foam stays comfortable for longer, adding to the saddle’s supportive platform. And a long central cut-out in the middle of the Zone relieves pressure on the perineum, allowing you to ride for longer.

Description

The Transmitter Carbon is long, low, slack and fun.

Stability and control at high speed. Better stand over clearance. Climbs really well and makes the most of any traction.

The 65 degree slack head angle is designed around a 150 mm fork and a 35 mm stem. When combined with short seat stays and that flattened, longer top tube you get an agile and confidence inspiring ride whether riding steep mountain trails or shredding the local woodland singletrack.

Transmitter Carbon makes best use of available technologies. Boost 148/110 standards and bolt through hubs mean a stiffer and more responsive ride. 650b+ tyres on a tubeless compatible wheelset mean loads of grip and control, whether climbing or descending.

Geometry and Sizing

Sizing

It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.

Generally we recommend:
Small: Riders between 5ft 2in and 5ft 7in
Medium: Riders between 5ft 6in and 5ft 10in
Large: Riders between 5ft 9in and 6ft 2in
X-Large: Riders of 6ft 2in +
