Stumpjumper EVO Alloy Frameset

Delivery Icon

We deliver! Just say when and how.

Let's get something clear, the Stumpjumper EVO Alloy isn't a "normal" trail bike. It's built to get gnarly, plain and simple. Featuring the same all-new design as its carbon brethren—including an adjustable head tube angle, 150mm of performance tuned travel, the adaptability of S-Sizing, and SWAT™ Door integration—in a lightweight yet tough M5 Alloy chassis, you're going to be able to bomb down trails that you thought you couldn't touch without a full-blown DH rig.

29” rear wheel shock link is included: 27.5” rear wheel link is available separately.

Gnar Ready

I was in the market for a daily trail machine that could survive the rugged New England conditions (roots of death and endless rock gardens) but at the same time be fun on machine-built trails and bike parks. Carbon is not the best choice here. My problem was finding an alloy bike with modern and fun geometry, and the Stevo Alloy was the answer. Another problem that Specialized helped me solve was finding a frameset. Most other companies are still in post-COVID mode and only sell complete bikes, which isn't an option for me because I always build my bikes. Pros: alloy, fun, fast downhill, good uphil, SWAT and 22oz bladder is an uber feature, no need to take a hip pack for longer rides. Cons: The shock is "too small" for this bike. It does the job, but this bike needs something more heavy-duty and progressive. Mediocre performance on flats, but that is not what this bike is meant for.

What a great frame

The stevo is a great bike and this frame is not the exception. I love how the mimic the form of the carbon version in this frame. The SWAT box is huge and is really light to be aluminum. The color is amazing too, it goes with everything you want to combine it, and you can easily convert the Float X Performance into Performance Elite with the fox compresion knob kit.

Great frame

I have the S4 AL paired with 190 mm Zeb. The bike is pure joy. It can eat absolutely anything and still climbs steep incline really well. Love the feel of it. Not too heavy. The geometry is just right. Riding at 64.5 but appreciate the ability to go 63.5. + having the SWAT box is really great.

Great Frame but not Brown like the photo.

I love this frame. Super adjustable. Buy it now! My only complaint is with the web/photo of this item. It isn't even close to brown on the base. It really is gunmetal gray. Fix your color maps Specialized!!!!

One bike to rule them all

Researched FS bikes for a year before purchasing. My non-negotiables were alloy, threaded BB, modern geo, boost spacing, 29er, and versatility. The stumpy evo alloy checked all the boxes. It’s not simply that this bike is able to be ridden on flat, flow, natural, or jump trails. It’s that it EXCELS on whichever types of trails you ride it on. Certainly the frameset can be purpose-built, but the engineered pedaling platform, travel amounts, and body positioning make it near perfect in all situations. Specialized nailed all the details as well; cable routing, SWAT box/tool, chain protection, headset system are all dialed. The colorway also looks great in real life, much deeper gun metal color vs the stock photos. If you want a bike that inspires confidence and puts a smile on your face no matter what type of trail you ride, the stumpy evo is the only choice.

Love the frame and the

Love the frame and the geo adjustability is incredible. Put a few runs down Downieville and Mt. Hough this year and this bike rips. I am 5'6" and am running a S3 with a mullet set-up. Extremely surprised at the pedaling efficiency as well. Incredible all-around bike, period.

Alloy love

I have been on specialized bikes for the last few years, and this is probably my favorite one! For me, this bike is the perfect middle ground between the stumpy and the Enduro. Playful, yet solid. Also, the fact that the SWAT box was available on the alloy frame made this one a no brainer for me.

Awesome Frame!

Super solid frame! Attention to detail is great and the frame feels robust while maintaining a fairly lightweight aluminum package. The SWAT door integration is such a great plus!! Plenty of storage space (more than the enduro) and sealed great to prevent water from touching whatever is inside. It is also very easy to clean, as most of the frame is very open and accesible which is always welcome. The geometry adjustments are quite simple and can be done fairly quickly to give a whole new ride feel. Overall a great frame to build a hard hitting trail bike with plenty of geometry adjustments to suit any riding style and terrain.
