The Shredder MTB Shorts: Common Questions
What are The Shredder MTB shorts and what makes them different from other Urban Cycling Apparel trail shorts?
The Shredder is Urban Cycling Apparel's dedicated off-road cycling short — a loose, baggy-fit MTB short built around three features that distinguish it from the Single Tracker and Flex MTB Trail Shorts in the lineup: the rear comfort stretch panel, the ClickFast detachable padded undershorts system, and the adjustable waist sizing straps. The rear stretch panel is a flexible fabric section across the back of the shorts that gives additional freedom of movement when you are in a weight-back descending position — one of the most demanding movements for fabric construction in trail riding. The ClickFast liner detaches cleanly for washing or separate use. The adjustable straps dial the waistband fit without a belt across a range of waist sizes within each size range. At $69 it bundles the outer shell and padded undershorts together rather than offering them separately.
What is the rear comfort stretch panel and why does it matter for aggressive trail riding?
The rear comfort stretch panel is a zone of flexible, higher-stretch fabric built into the back of the outer shorts. In a standard woven fabric construction, the back panel of a baggy short creates the most resistance when you push your hips back behind the saddle — the fundamental body position for steep descents, rock drops, and technical MTB terrain where keeping your weight rearward is essential for control. A rigid back panel limits how far back you can shift and creates pressure and bunching at the waistband and seat. The stretch panel eliminates this resistance specifically in the movement zone that matters most for off-road riding, letting you move your hips freely without fighting the fabric. Riders who spend time on technical descents at places like Coler Mountain Bike Preserve, Slaughter Pen, or any trail system with sustained steep sections will notice this difference on the first ride.
What is Coolmax fabric and why is it used in the padded undershorts?
Coolmax is a branded high-performance polyester fiber developed specifically for moisture management — it is engineered with a cross-shaped fiber cross-section that dramatically increases surface area compared to standard round polyester fibers, allowing it to wick moisture away from the skin and spread it across a larger area for faster evaporation. In the context of padded MTB undershorts, Coolmax addresses the specific problem of sweat accumulation in the chamois zone during hard trail efforts. Standard liner fabrics absorb moisture and stay damp, creating a warm, wet environment against the skin that causes chafing and bacterial growth over the course of a long ride. The Coolmax construction actively moves moisture out and away, keeping the contact surface cooler and drier. The antibacterial treatment adds a second layer of protection against odor and irritation, which is particularly relevant for multi-day riding trips or multiple consecutive ride days.
How does the ClickFast detachable undershorts system work?
The ClickFast system uses attachment points inside the outer shell that connect to corresponding points on the padded undershorts, holding the liner in position during riding without permanent attachment. This means the liner stays in place when you are on the bike — the chamois does not shift or bunch inside the outer short — but releases easily for separate washing or for wearing the liner independently. The practical benefits are straightforward: the outer shell and padded liner can be washed separately at different frequencies (outer shells go less often, liners ideally after every ride), the liner can be worn under other shorts when needed, and riders who already own quality bib shorts can remove the ClickFast liner and use their preferred chamois inside the Shredder shell. The detachable construction also extends the lifespan of both garments since wear patterns differ between the outer shell and the liner.
How do The Shredder shorts compare to The Single Tracker?
The Shredder and The Single Tracker are both baggy MTB shorts with padded liner options, but they are built around different priorities. The Single Tracker uses heavier Cordura fabric for maximum abrasion resistance and durability, with a seamless inner panel that eliminates rubbing in the under-thigh contact zone — it is the more rugged, longer-lasting option for riders who prioritize durability and chafe prevention above all else. The Shredder prioritizes freedom of movement — the rear stretch panel gives it more dynamic range through technical body positions than the Single Tracker's stiffer construction, and the ClickFast liner system is a more refined attachment mechanism than the Single Tracker's integrated approach. Riders who do aggressive technical MTB with frequent steep descents and dynamic body positioning tend to prefer the Shredder. Riders who prioritize maximum durability and the anti-chafe seamless panel lean toward the Single Tracker. Both run small — size up one from your normal measurement.
How should I size The Shredder and what do the adjustable waist straps do?
The Shredder runs small — this is consistent feedback across all retail channels and is confirmed by reviewers who note they typically wear a large but found an XL fit perfectly. Order one size up from your normal waist measurement. The adjustable waist sizing straps are side-mounted adjusters that tighten or loosen the waistband around your actual waist measurement independently of the nominal size, giving you a precise fit within the size range rather than relying on a fixed waistband alone. This is particularly useful for riders whose waist measurement falls between standard sizes, or who want a looser or more secure feel depending on the intensity of the riding. The straps also accommodate layering — tightening slightly when you are wearing a base layer or looser clothing underneath the shorts on cold days. Urban Cycling Apparel ships direct from its Webb City, Missouri fulfillment center.
Great riding shorts

United StatesChristian
These riding shorts are absolutely great for all kinds ofriding, I was sent an XL by mistake but they fit perfectly, so sizings runs small. I'm usually a large. Finally, I would like to be able to order the shorts without the padded under shorts.
United StatesWell Rounded option
I rode 289 miles on my first time out. The fit was just right, I like the pockets and the adjustment option the waist affords. Buy local and small.
United Statesthe shredder MTB shorts
Great, love the shorts. I need to order another pair, maybe another color.
United StatesThe Shredder Shreds
I have bought the Grey and Black shorts and are 99.9% happy with the shorts. The only issue I faced was the zippers. They easily got hung up on the fabric when closing. I found a YT video that showed how to correct this. Only had to use a needle nose pliers to compress the zipper clasp, and now it works smoothly. The shorts are perfect In the hottest weather and dry quickly from sweat. They are my go to shorts for all my MTB rides. The chamois that come with them, run a little too big, but the padding is good.
