Ideal for riders on a 26in or 27.5in MTB with a fixed seatpost who want a proper step up from a tiny emergency mudguard without moving to a larger, heavier rear fender setup.
If you want a rear mudguard that’s quick to fit and easy to live with, the ZEFAL Deflector RM60 hits a very useful middle ground. It gives you high rear-wheel spray protection in a compact format, with a seatpost-mounted MD-Turn system that keeps the install straightforward and lets you fine-tune the angle for better coverage on your bike.
For the rider, the big win is comfort. A rear guard like this helps keep mud, grit and water off your back and shorts, which matters on wet singletrack, fire roads and winter bike-path rides. Compared with ultra-minimal saddle-rail guards, this style sits lower and closer to the tyre, so you get a more meaningful reduction in spray. Compared with bigger full-coverage rear guards, it stays lighter and simpler, with less bulk on the bike.
This model suits bikes with a round seatpost from 25–32 mm, clears 26in and 27.5in wheels, and is rated for tyres up to 2.6in. The dual-material spoiler adds a bit of flex at the trailing edge, and the reflective ring is a handy extra if your rides finish in low light. The main thing to know before buying is compatibility: it is not suitable for telescopic seatposts, so it’s best on hardtails, older MTBs and commuter conversions running a fixed post.
High rear spray protection
Designed as a rear MTB mudguard with a longer blade shape that gives more meaningful coverage than a basic saddle flap.
MD-Turn seatpost mount
The quick screw-on seatpost mount keeps installation simple and gives a secure, tidy fit on compatible bikes.
Adjustable positioning
You can fine-tune the mudguard angle to sit neatly with the bike and improve where the spray protection lands.
Dual-material spoiler
The spoiler adds extra coverage while keeping some flexibility, so it’s less harsh and better suited to rough off-road use.
Light 166 g build
Adds useful mud protection without a big weight penalty or a bulky full-length feel.
Low-light visibility detail
A reflective ring adds a small but useful visibility boost for early starts, late finishes and winter commuting.
Made in France
A good option if you value established European accessory design and local manufacturing heritage.

MD-Turn
This quick screw-on seatpost mount makes fitting simple and lets you dial in the mudguard position on seat posts from Ø 25 to 32 mm for a secure, tidy setup.
Adjustable Fit
You can fine-tune the position to sit neatly on the bike, helping you get better coverage where it matters most on wet and muddy rides.
Dual Material Spoiler
The dual-material spoiler adds extra coverage while keeping some flex, so you get better splash protection without the mudguard feeling overly rigid.
Visibility
A reflective ring helps you stand out better in low light, adding a little extra visibility for night riding.
Great for
Maybe not for
Fits seatposts from 25–32 mm and suits 26in / 27.5in wheels with tyres up to 2.6in. Not suitable for telescopic seatposts. As with other seatpost-mounted rear guards, leave enough tyre clearance through suspension travel and recheck tightness before rides.
vs SKS X-BLADE
The SKS X-BLADE is a direct rival in the seatpost-mounted rear MTB mudguard category, with a longer rear section and support for wider tyres up to 3.0in.
vs Topeak DeFender XC11
The Topeak DeFender XC11 is another seatpost-mounted rear mudguard with quick-release clamp mounting and multi-angle adjustment, aimed at easy on-off use.
vs Mudhugger MK2 Rear Mudhugger
The Mudhugger MK2 Rear Mudhugger is a larger rear option for riders who prioritise maximum muck protection over compact size and clean looks.
Best on fixed-seatpost MTBs
This is the key buying point: if your bike runs a dropper post, skip it. On a fixed-post hardtail or an older 26in/27.5in MTB, it makes far more sense.
More useful than tiny saddle flaps
If you’ve tried ultra-minimal mudguards and still ended up with a wet backside, this longer rear profile is the kind of upgrade that usually feels worthwhile straight away.
Seatpost size matters
Check your seatpost diameter before ordering. The mount range is 25–32 mm, so it won’t suit every oversized post even on otherwise compatible bikes.
Allow suspension and tyre clearance
On any bike with rear suspension movement, leave safe clearance to the tyre through full travel. A neatly adjusted mudguard works better and is less likely to rub.
