TUSITA Cycling Saddle Bag Clip Mount (Small Slot) Compatible with Garmin Varia RTL515, RTL510, RVR315, RearVue 820
Quick take
This TUSITA clip mount is designed to attach compatible Garmin Varia rear-view devices to your bicycle saddle bag or rear trunk bag using a Garmin quarter-turn system. Reviews consistently point to a snug, stable fit and durable-looking composite/plastic construction, with the main tradeoff being that strap fit can be tight to remove and one report of a mishap suggests it is worth rechecking the mount is fully seated before rides.
Pros and cons
Pros
- Secure, stable clamping on rear bag straps, designed to keep the Varia from shifting during rides.
- Supports Garmin Varia models including RTL510, RTL515, RVR315, and RearVue 820.
- Adjustable orientation capability (buyers describe changing bracket orientation for their preferred setup).
- High-strength composite construction, with users noting durable-feeling plastic.
Cons
- Can be “on tight” on some bags, which may make installation and removal less effortless.
- Fit on certain bag strap systems can require careful seating, since a poorly seated mount has been reported to come off.
- Some buyers find it pricier than expected for a mount-only accessory.
What buyers think
Buyer-review evidence is supportive overall, with a recurring theme that the mount fits snugly on compatible saddle and trunk bag setups and holds the device firmly. Multiple reviews describe the mount as feeling durable, stable over rough terrain, and secure enough that the Varia stays in place. There is also positive feedback about orientation flexibility, including reports that the bracket can be reconfigured to suit different mounting preferences. The main negatives cluster around value (some feel the price is high for a mount) and usability on specific bags (tight strap fit and the importance of confirming the mount is fully seated to prevent it from coming loose).
Design and compatibility, in plain terms
This is a saddle bag clip mount made for rear-facing Garmin Varia devices that use the Garmin quarter-turn mounting interface. It’s intended to mount on the strap area of compatible bicycle rear bags (saddle bags, trunk bags, and similar setups) so the rear radar/light remains unobstructed for detection and visibility.
Supported Garmin devices
- Garmin Varia RTL510
- Garmin Varia RTL515
- Garmin Varia RVR315
- Garmin RearVue 820
Installation and day-to-day usability
Reviews repeatedly describe the install as straightforward, with users appreciating how solidly it clamps once positioned. At the same time, several comments suggest the clamp can be tight on certain bag strap geometries, which is helpful for stability but can make removal more work than you might expect. If your bag’s strap material or width is close to the tolerance limits, take an extra moment to confirm the mount sits completely and evenly before heading out.
Orientation flexibility
One of the practical benefits highlighted by reviewers is the ability to change mounting orientation to better match how you want the RTL515 presented. That kind of adjustability matters if your ideal mounting position is not the “default” vertical alignment.
Pros and cons, expanded
Where this mount makes sense
- You want to mount a Garmin Varia directly on a rear seat/trunk bag rather than a dedicated seatpost mount.
- You prioritize stability, the device staying firmly in place on rides that include bumps or rougher trails.
- You care about keeping the rear view unobstructed, especially when visibility and detection depend on the angle and clear line of sight.
- You may want orientation flexibility, so the RTL515 can be positioned the way you prefer.
Where you might want to look elsewhere
- Your bag strap setup is hard to seat consistently, or you want a mount that goes on and comes off with minimal force.
- You’re very budget-sensitive and would rather spend less on a mount-only accessory (some buyers felt the price was higher than expected).
- You cannot commit to quick pre-ride checks to ensure the mount is fully seated on your specific bag strap.
Price and availability
Pricing can vary, and this mount is positioned as a specialty Garmin Varia bag accessory. If you see it at a higher-than-average cost, weigh it against your need for a stable bag-mounted setup and whether you already have a strap system that reliably mates with the clip.
Verdict: is it worth it?
The TUSITA saddle bag clip mount is a strong fit if you run a compatible Garmin Varia and want a stable, bag-mounted rear setup, especially when you value an adjustable orientation and a clamp that feels secure. The key things to get right are ensuring the mount seats cleanly on your bag strap and accepting that tight clamping can make removal less effortless. If you want an easy on/off mount regardless of bag geometry, you may need to compare other mounting approaches.
FAQ

Yes. This clip mount is made for Garmin Varia RTL510 and RTL515 devices that use the Garmin quarter-turn mounting interface.
Can the mount be adjusted for different mounting orientations?
Buyers report that the bracket can be reconfigured so you can choose a more suitable orientation for your setup, including changing orientation by rotating the bracket components.
Does it stay secure on rough rides?
Most review themes describe the clamp as stable, with the mount holding position during rides and on rougher terrain. As with any bag-mounted accessory, it’s still important to confirm the mount is fully seated before riding.
Is it easy to install and remove from a saddle bag?
Installation is generally described as straightforward, but some buyers note it can be fairly tight to get on and can be difficult to remove, depending on the bag strap design.
What’s included in the box?

What kind of bags is it meant for?
It’s intended for rear seat/trunk bag strap areas, meaning saddle bags and similar rear bags where the mount can clamp securely onto the strap region.
