The Mountain Biker’s Road Bike

I have been riding the Stigmata since its return in 2015 to the Santa Cruz lineup and have it used as both a road bike for training and a gravel bike for exploring the endless logging roads of Squamish over the years. It was the perfect training tool, though I did find the CX tires and 700cc wheels did not gel as well on the chunky logging roads as they did for CX racing.

Fast forward to 2020 and we have seen the gravel adventure market really take off. The Stigmata has evolved with a few geometry tweaks and most notably, a frame that can now take 27.5 wheels, allowing for wider tires and a more comfortable ride on the chunkiest of fire roads. Companies like Shimano and Enve now have gravel specific lines of components that can handle more technical and rough terrain, creating better bike handling and all around riding experience.

With these new advancements, I have built up a Stigmata with the aim of making a bike that will be well-equipped for gravel adventures, but with the flip of a wheel set can become a capable road bike as well. This new build is the mountain biker’s road bike and I have spent the last month breaking this bike in on the extensive gravel trail network around Squamish. Hopefully when this current situation passes, I will be able to get out on some bigger adventures in the summer months.

Let’s start off with the frame. I’m 6’1″, so I went with the size 58 carbon cc frame. The Stigmata currently comes in two colours: olive green and mustard. I was pretty set on olive green, but I was drawn in by the brighter colours of the mustard and in the end it’s what prevailed. Check the frames and bike builds from Santa Cruz Bicycles here –

The drivetrain is Shimano’s new GRX line of components made for gravel specific adventure. I was pretty keen on a simple 1×11 setup, but went with 2×11 so I have a bigger gear range if I decide to switch wheelsets and use it for road riding also.

It consists of a Shimano Ultegra 11-32 cassette with a GRX 11 speed rear derailleur with on and off chain tensioner. This derailleur has really eliminated any chain slap and I have not yet engaged the chain tensionser lockout. I’m also running the GRX 2×11 speed cranks with a 41-38 tooth setup.

The pedals are bomb proof Shimano XTR SPDs most commonly used on XC mountain bikes. The front and rear rotors are 6 bolt, 160mm Shimano.

The brakes are powered by Shimano GRX hydraulic disc brake dual control levers. The cockpit consists of a 100mm Enve road stem with Enve’s G series bars that are nice and wide, offering plenty of comfort and control.

I wrapped the bars with Enve’s 3mm handlebar tape, which provides comfort and a clean finish to the cockpit.

Wheels are rolling on R45 Chris King 24 hole hubs in matte jet. You really can’t beat the made-in-house bearings that run in all Chris King hubs.

Wheels are built on 27.5 Enve G series rims made for higher volume tires to handle rougher and technical terrain. The tires are Maxxis Race TT 27.5x 2.0, which are a fast-rolling XC race tire tightly packed with ramped square knobs. For road riding, I will keep my exisitng wheelset, which consists of Enve’s SES 4.5 AR discs with 28mm slick tires.

This bike is another great tool for exploring the outdoors and taking you to places beyond where you would normally venture on a mountain bike.
