The Selle SMP VT20C is the compact version of the longer Selle SMP VT20. It retains the supportive width and characteristic pressure-relief features while reducing the length from 280mm to 255mm, making it easier for riders to move between seated positions.

Selle SMP VT20C AISI 304

Rail material: AISI 304 stainless steel

Rail finish: Matte Black

Rail diameter: 7.1mm round

Claimed weight: Approximately 260g

Dimensions: 255x144mm

Padding: Intermediate SSPU

Cover: SVT Velvet Touch

Base: Carbon-reinforced Nylon 12

The stainless-steel version is the practical choice for riders who prioritise rail durability, conventional seatpost compatibility and improved vibration absorption over minimum weight.

Its AISI 304 stainless-steel rails are particularly suitable for regular riding in wet, humid or coastal Australian conditions because they offer excellent corrosion resistance and durability.

Selle SMP VT20C Carbon

Rail material: Unidirectional carbon fibre

Rail dimensions: 7.1x9.0mm oval

Claimed weight: Approximately 205g

Dimensions: 255x144mm

Padding: Intermediate SSPU

Cover: SVT Velvet Touch

Base: Carbon-reinforced Nylon 12

The carbon-railed Selle SMP VT20C saves approximately 55g compared with the stainless-steel model. It is best suited to premium road bikes, custom gravel builds and riders pursuing a lower complete-bike weight.

The seatpost clamp must be approved for 7.1x9.0mm oval carbon rails. A clamp intended only for round metal rails can damage the carbon structure.

Selle SMP VT20C GEL

A GEL version is also available for riders wanting greater impact and vibration absorption.

Dimensions: 255x144mm

Padding: SSPU polyurethane with a self-moulding GEL layer

AISI 304 rail weight: Approximately 290g

Carbon rail weight: Approximately 235g

Manufacturer-reported pressure reduction: Up to 30% at selected anatomical contact points

The GEL version uses different quantities of cushioning across the contact area, with more material positioned where the rider applies greater pressure. It is particularly relevant to gravel riders, endurance cyclists and riders travelling over coarse or damaged roads.

Designed on Your Body Ergonomics

The Selle SMP VT20C uses the brand’s Designed on Your Body ergonomic philosophy.

Rather than relying on thick and uniformly soft padding, the saddle is designed to support the rider primarily through the sit bones while creating clearance around sensitive central tissue.

The shape combines:

A supportive rear platform
A broad central pressure-relief channel
A compact front section
A dropped eagle-beak nose
A rear depression designed to protect the coccyx
Long rails offering extensive adjustment

This approach aims to improve pelvic stability, reduce unwanted central pressure and allow the rider to maintain comfortable forward pelvic rotation during road, gravel and triathlon riding.

Compact 255mm Length

The “C” in Selle SMP VT20C identifies the compact version of the Selle SMP VT20.

At 255mm long, the Selle SMP VT20C is 25mm shorter than the 280mm Selle SMP VT20. This removes unnecessary material ahead of the rider while preserving enough usable length for positional movement.

Advantages include:

Easier movement into an aggressive riding position
Reduced interference at the front of the saddle
Greater freedom when riding out of the saddle
Improved movement during technical gravel and MTB riding
Better support when moving forward during hard efforts
Lower overall weight
Modern compact proportions

Unlike some heavily truncated short-nose saddles, the Selle SMP VT20C still provides useful fore-and-aft movement rather than forcing every rider into one fixed position.

Flatter VT-Series Profile

The Selle SMP VT20C has a flatter upper profile than traditional strongly waved Selle SMP saddles.

This flatter platform is designed for cyclists who move more frequently along the saddle and prefer less pronounced rear containment.

The shape can make it easier to slide into different positions while retaining Selle SMP’s central pressure relief, eagle-beak nose and coccyx-protecting rear depression.

This makes the Selle SMP VT20C particularly relevant to:

Road racers changing position as effort varies
Gravel riders moving over uneven terrain
Climbers shifting forward on steep gradients
Triathletes using a rotated pelvic position
Mountain bikers moving dynamically around the bicycle

Full-Length Pressure-Relief Channel

The central channel extends through most of the saddle rather than appearing as a small cut-out in one location.

Its purpose is to create space for tissue, nerves and blood vessels that should not carry a large proportion of the rider’s weight.

Potential benefits include:

Reduced central pressure
Improved blood-flow management
Reduced numbness for compatible riders
Greater comfort during pelvic rotation
Better support while riding in the drops
Relief during long seated climbs
Improved airflow

The channel cannot compensate for incorrect saddle width, excessive saddle height or excessive handlebar reach. Persistent discomfort should be assessed through a complete professional bike fit.

Eagle-Beak Nose

The front of the Selle SMP VT20C curves downward into Selle SMP’s characteristic eagle-beak profile.

This shape is designed to reduce pressure when the rider moves towards the front of the saddle or rotates the pelvis into a more aggressive position.

Potential benefits include:

Reduced pressure at the front
Greater freedom during forward movement
Less interference when riding low over the handlebars
Improved clearance during technical riding
Support without a raised conventional nose

The unusual nose shape means its position should not be copied from another saddle using only the nose-to-handlebar distance.

Rear Coccyx Depression

A depression at the rear of the saddle creates additional clearance around the coccyx.

This can be useful during rough-road, gravel and mountain bike riding, where impacts may cause the pelvis to move against the rear of a conventional saddle.

The feature is designed to reduce direct contact during:

Corrugations
Pothole impacts
Rough gravel
Rocky trails
Sudden seated compression
Technical off-road riding

SSPU Padding

The Selle SMP VT20C uses soft polyurethane padding with high mechanical resistance.

Its intermediate padding level provides cushioning without allowing the rider to sink excessively into the saddle.

Potential benefits include:

Controlled compression
Stable sit-bone support
Vibration absorption
Resistance to permanent deformation
Support during sustained power
Greater comfort than a minimalist racing saddle

A deeply padded saddle can feel comfortable during the first few minutes but create instability, friction and increased pressure during longer rides. The Selle SMP VT20C instead uses a moderate amount of supportive padding over an anatomically shaped base.

SVT Velvet Touch Cover

The Selle SMP VT20C uses an SVT Velvet Touch cover.

The cover is formed through Selle SMP’s Vacuum Tech process, allowing it to be applied without conventional adhesives or mechanical fasteners.

Potential benefits include:

Clean external finish
Consistent surface tension
Fewer seams and attachment points
Reduced risk of adhesive deterioration
Smooth movement across the saddle
Resistance to routine perspiration and moisture

The cover should still be protected from sharp tools, abrasive saddle bags, aggressive chemicals and prolonged exposure to excessive heat.

Carbon-Reinforced Nylon 12 Body

The saddle base combines Nylon 12 with carbon-fibre reinforcement.

This construction is designed to balance:

Structural stability
Controlled flexibility
Low weight
Resistance to repeated loading
Secure rail attachment
Long-term dimensional consistency

The shell must remain stiff enough to stabilise the pelvis but flexible enough to work with the padding and rails to moderate vibration.

AISI 304 Stainless-Steel Rails

The standard Selle SMP VT20C uses matte-black AISI 304 stainless-steel tubing.

Advantages include:

Strong corrosion resistance
High mechanical strength
Conventional round-clamp compatibility
Durability in wet conditions
Better impact tolerance than carbon
Useful vibration absorption
Lower replacement cost

The 7.1mm round profile is compatible with many common two-bolt seatpost clamps, although compatibility should always be checked before installation.

Unidirectional Carbon Rails

The premium Selle SMP VT20C uses unidirectional carbon rails measuring 7.1x9.0mm.

Advantages include:

Approximately 55g lower weight
High structural stiffness
Direct pedalling response
Premium construction
Suitability for lightweight custom builds

The oval rails require an appropriate carbon-rail seatpost clamp. Installation must remain within the marked clamping area and follow the torque stated by the seatpost manufacturer.

Structural Fixing Plates

Selle SMP uses dedicated structural fixing plates at the rail-to-shell interfaces.

These plates are designed to increase strength and distribute loads through the base more effectively.

Potential benefits include:

Strong rail retention
Improved resistance to repeated loading
Stable shell support
Greater durability
Reduced stress concentration

Recommended sit-bone spacing: 90mm to 125mm
Suggested clothing size: XS to M
Padding level: Intermediate

Selecting the Selle SMP VT20C

The Selle SMP VT20C is most likely to suit riders who:

Have medium-to-narrow sit-bone spacing
Prefer a compact saddle
Move frequently between riding positions
Use a forward-rotated road or triathlon posture
Require substantial central pressure relief
Prefer moderate rather than excessive padding
Need a multidisciplinary saddle for road and gravel

A rider with sit-bone spacing greater than approximately 125mm may be better suited to the wider Selle SMP VT30C.

Selle SMP VT20C Versus Selle SMP VT30C

Selle SMP VT20C:

144mm wide
Recommended for 90mm to 125mm sit-bone spacing
Better thigh clearance
More compact support area
Suitable for medium-to-narrow pelvis dimensions

Selle SMP VT30C:

Wider support platform
Better suited to broader sit-bone spacing
Increased rear support area
May feel more stable for riders who find the Selle SMP VT20C too narrow

Additional width should be chosen according to anatomy and riding posture rather than rider height, weight or gender alone.

Saddle Positioning

Initial setup should consider:

Saddle height
Saddle setback
Saddle angle
Sit-bone support position
Rail position
Pelvic rotation
Handlebar reach
Handlebar drop
Rider mobility
Weight distribution

Because the Selle SMP VT20C has a compact and dropped nose, its position should not be copied from another saddle using nose-to-handlebar distance alone.

The effective seating centre and rider’s hip position provide more useful references.

Saddle Tilt

The Selle SMP VT20C may require a slightly nose-down orientation, but the correct setting depends on the rider and complete bicycle position.
Excessive downward tilt can cause the rider to slide forward, increasing pressure through the hands, wrists and shoulders.
Excessive upward tilt can increase central pressure and restrict pelvic rotation.

The Selle SMP VT20C is best suited to road, gravel, cross-country and triathlon riders with medium-to-narrow sit-bone spacing who want a compact saddle (and flatter VT profile) with extensive pressure relief and enough freedom to move between positions.

Professional Saddle Fitting

Professional fitting is strongly recommended before purchase.

A complete assessment should consider:

Sit-bone spacing
Pelvic shape
Pelvic rotation
Rider flexibility
Saddle height
Saddle setback
Saddle tilt
Handlebar reach
Handlebar drop
Current pressure symptoms
Pedalling movement
Typical ride duration

A sit-bone measurement provides useful guidance but should not replace dynamic assessment on the bicycle.

Installation

Confirm that the seatpost clamp is compatible with the selected rail.

AISI 304 rails:

7.1mm round
Compatible with many conventional round-rail clamps

Carbon rails:

7.1x9.0mm oval
Require a suitable oval-rail clamp

Before tightening:

Clean the rails and seatpost clamp.
Confirm the correct clamp orientation.
Position the clamp within the marked rail area.
Align the saddle with the bicycle centreline.
Set the initial tilt.
Tighten to the seatpost manufacturer’s specified torque.

Always use a calibrated torque wrench.

Cleaning

Clean the Selle SMP VT20C with:

Mild bicycle cleaner
Warm water
A soft cloth
A soft brush around the central channel

Avoid:

Petroleum-based cleaners
Aggressive solvents
Abrasive brushes
Silicone dressing
Pressure washing
Prolonged soaking
Excessive heat

Allow the saddle to dry naturally after wet or muddy rides.

Routine Inspection

Inspect the saddle regularly for:

Bent or cracked rails
Deep scratches in carbon rails
Rail separation
Base damage
Torn cover material
Damaged channel edges
Excessive padding compression
Unusual movement
Creaking
Loose seatpost hardware

Stop riding if a rail is cracked, crushed, bent or separating from the saddle base.

Carbon-Rail Care

Inspect the carbon rails after:

Crashes
Transport incidents
Overtightening
Seatpost movement
Significant impacts
Accessory installation

Do not attach saddle bags or accessory clamps directly to carbon rails unless compatibility is specifically confirmed.

Bici da Strada published a technical test of Selle SMP VT20C GEL in 2022.

The GEL version shares the same compact 255mm length, 144mm width, flatter VT profile, central pressure-relief channel and eagle-beak nose as the standard Selle SMP VT20C, but adds a self-moulding GEL layer.
They found the compact shape particularly effective for riders who move along the saddle. Its flatter upper surface made it easier to shift position compared with Selle SMP’s more deeply waved traditional designs.
The large pressure-relief channel reduced central loading, while the dropped nose provided useful clearance when the rider moved forward or rotated the pelvis into an aggressive position.
The GEL layer was praised for reducing vibration across rough roads and gravel without creating an excessively soft or unstable feel.

Riders with previous experience of Selle SMP Evolution, Selle Italia SLR and Flite saddles have praised the Selle SMP VT20C’s support and modernised shape.
