The Troy Lee Designs Stage Pro knee pads are built for trail, enduro and eMTB riders who want serious impact protection without the heat and bulk of a traditional gravity guard. They combine a flexible D3O Diablo insert with a long, close-fitting sleeve and broad upper and lower cuffs.
On the trail, that balance works extremely well. The Stage Pro pads feel comfortable while pedalling, cover the kneecap and upper shin properly and remain securely positioned without needing external straps. The material behind the knee also breathes well enough for sustained riding and repeated climbs.
The main weakness is the limited choice of sizes. TLD offers three combined size bands rather than a full run of individual sizes, so the shape will not suit every thigh and calf combination. Riders between sizes may struggle to get the same secure, unobtrusive fit.

Troy Lee Designs Stage Pro knee pads review
Comfort and pedalling
The Stage Pro pads feel softer and less restrictive than their Level 2 rating might suggest. The pre-shaped D3O insert follows the knee as it bends, while the Lycra sleeve stretches without pulling against the leg at the top of each pedal stroke.
That makes them easy to leave on for an entire ride. They do not have the rigid, armoured sensation associated with bulkier downhill pads, and there was no significant bunching behind the knee during normal pedalling. For eMTB riding, where repeated climbs and descents can mean wearing protection for several hours, that comfort matters as much as the certification.
Protection and coverage
The centrepiece is the D3O Diablo insert, certified to EN 1621-1:2012 Level 2. It remains flexible during ordinary riding but is designed to absorb and disperse energy during an impact. The protector covers the kneecap properly and continues a useful distance down the upper shin.
The slim shape makes that coverage feel less cumbersome than expected. The front material also provides an abrasion-resistant layer over the insert. I did not deliberately impact-test the pads, so the protection assessment is based on the certified rating, construction and the way the guard stays centred over the joint.
There is less additional padding around the sides of the knee than on some heavier gravity guards. The Stage Pro therefore makes most sense as a highly protective trail and enduro pad that remains comfortable to pedal in. Riders regularly tackling very exposed downhill terrain may prefer a guard with broader lateral padding.
Secure fit and breathability
The broad cuffs and internal grip work well. Once positioned, the Stage Pro pads showed very little tendency to ride up or slide down, even as the knee moved repeatedly through the pedal stroke. Avoiding external straps also keeps the profile clean beneath shorts or riding trousers.
Airflow is another strong point. The insert is extensively ventilated, while the Air Channels and lighter material behind the leg help heat and moisture escape. The pads are still warmer than the thinnest Level 1 sleeves, but they are impressively breathable for the amount of certified protection supplied.
What is not so good?
The limited size range is the clearest problem. XS/S, M/L and XL/XXL cover a wide spread of riders on paper, but combining two conventional sizes into each option leaves less room to match different thigh and calf shapes. A rider with a larger thigh and slimmer calf, or the reverse, may find one cuff comfortable while the other feels too tight or loose.
Accurate measurements are therefore essential. These pads work so well because the sleeve fits closely and the cuffs hold firmly; choosing a compromised size can undermine both the comfort and the stability praised during testing.
The second limitation concerns their role rather than their basic performance. The Level 2 insert offers serious central protection, but riders wanting maximum coverage around the sides of the knee should compare the Stage Pro with a broader gravity-oriented pad.
Final verdict
The Troy Lee Designs Stage Pro knee pads deliver an excellent balance of comfort, secure fit and certified protection. They cover the knee and upper shin well, stay where they are placed and remain breathable enough for long trail and eMTB rides.
Their strongest quality is how little compromise the Level 2 protection demands while pedalling. The flexible insert and close sleeve move naturally, while the broad grippers prevent the repeated slipping and adjustment that can make other knee pads frustrating.
The narrow sizing choice prevents an unconditional recommendation because the fit will not work for every leg shape. If one of the three sizes matches your measurements, however, the Stage Pro is a very comfortable and reassuring option for trail, enduro and aggressive eMTB riding.
Troy Lee Designs Stage Pro knee pads
£94.99 (RRP £110)
Choose the Stage Pro if you want Level 2 knee protection that remains comfortable and breathable during sustained pedalling. Measure carefully before ordering because the three combined sizes leave less room for an in-between fit.
Troy Lee Designs Stage Pro alternatives
Bluegrass Aura Core
£122
The Bluegrass Aura Core is the alternative for riders wanting broader Level 2 Type B protection and a more conventional choice of five individual sizes. It adds side and upper-shin padding while retaining a relatively slim, pedal-friendly sleeve. It costs more and feels slightly more substantial, but the wider size range may solve the Stage Pro’s main weakness.
Endura MT500 D3O Ghost
£80.99 (RRP £95)
The Endura MT500 D3O Ghost prioritises minimum bulk and maximum airflow. Its very flexible Level 1 insert makes it particularly comfortable for long, warm or pedal-heavy rides, but it does not provide the same impact rating as the Stage Pro. Choose the Endura for lighter everyday trail protection and the TLD for rougher riding.
7iDP Sam Hill
£54.99
The 7iDP Sam Hill is a much cheaper route to Level 2 protection. Its long compression sleeve, side protection and breathable rear mesh make it a strong choice for trail and enduro use. The Stage Pro feels slimmer and uses the newer, highly flexible D3O Diablo insert, while the 7iDP focuses on straightforward protection and value.
Troy Lee Designs Stage Pro knee pads FAQs
What protection level do the TLD Stage Pro knee pads provide?
The D3O Diablo insert is certified to EN 1621-1:2012 CE Level 2. That is the higher of the two impact-performance levels commonly found in flexible MTB knee pads.
Are the TLD Stage Pro knee pads comfortable for long rides?
Yes, provided the size suits your leg shape. The flexible insert, stretch Lycra body and contoured sleeve allow a natural pedal stroke without excessive bunching behind the knee.
Do the TLD Stage Pro knee pads slip while riding?
They stayed securely positioned during testing, with very little upward or downward movement. Wide upper and lower cuffs and the TLD Pad Anchor system provide grip without external straps.
What sizes are available?
Troy Lee Designs offers XS/S, M/L and XL/XXL. Because these are broad combined sizes, measure both the thigh and calf carefully and compare them with the current TLD size chart before ordering.
Are the TLD Stage Pro pads suitable for bike parks and downhill riding?
The Level 2 insert makes them suitable for aggressive trail and enduro riding, including many bike-park sessions. Riders prioritising maximum gravity protection may prefer a bulkier guard with more padding around the sides of the knee.
