Dundas Speed Shop

The Maxxis Reaver is designed for gravel racing when off-road speed is priority number one. 

Tread:
The Reaver’s diamond knurling center tread is low and fast for carrying speed while the tire’s meaty side k***s offer consistent cornering traction allowing the rider to maintain speed in turns.

Sidewall protection:
EXO is extremely cut-resistant and abrasion-resistant material added to the sidewalls of the Reaver for extra protection on trails where the chance of sidewall cuts and abrasions are high.

If you are a rider who tackle routes that are about 50% paved roads and 50% gravel, hard-packed dirt, or asphalt (Sounds like the Dundas Valley!), and want confidence at high gravel speeds, lets chat about the Reaver as a potential option you.

Available in 700x40c and 700x45c

The Cervélo Áspero with Rival XPLR AXS — a build kit that Cervélo cannot keep in stock!

This bike is hard to find right now and we just happen to have one in a 56cm frame size. The Rival XPLR AXS 1 groupset is on a stealthy and fast looking black/charcoal frameset, finished with dark glittery silver decals. This bike screams fast and rowdy.

The Rival XPLR 40T | 10–46T | 13-speed drivetrain has been super popular and that extra gear is a welcome addition for gravel. This build is made for riders who love attacking trails at speed. Just look at those wheels.

The Rival groupset brings trickle-down tech from SRAM RED, but with a more affordable price tag thanks to clever material choices. Cervélo pairs it with Reserve 40|44 GR wheels — 40mm up front, 44mm out back — their fastest, most stable gravel wheels yet, and can fit up to a 50mm tire.

If you’re a 56cm, this exact bike could be yours today. Not your size? No worries — we can still get you the perfect fit in your dream colour and build. Come check it out in person, or send this to a friend who’s looking.

Back in stock! The Oi! Luxe Bike Bell from makes bike bells sexy and discreet, fitting seamlessly onto any circular handlebar. It is a work of art with ding that’s loud but pleasant.

Oi Luxe features a CNC-machined ringer, brass dinger, stitched vegan ‘leather’ shim and metal injection-moulded stainless steel. It’s made to last and is a joy to have on your handlebar.

Available in two sizes:
Small fits 22.2mm bars
Large fits 23.8 – 31.8mm bars

The Continental Grand Prix 5000 S TR is the road tire I use on my Cervélo Soloist, and it handles itself surprisingly well when I take it onto gravel, which is easy to do when you live, work, and ride close to the rail trail.

The Grand Prix 5000 and 5000 S TR are still the benchmark for all-season road riding around here. If you like reduced rolling resistance (riding faster), vibration-dampening compounds (staying comfortable), and increased puncture protection (fewer flats), the GP 5000 could become your new best friend — if it isn’t already.

All of Continental’s high-end tires, including the GP 5000 lineup, are handmade in Germany, and there’s no shortage of sizing options. The clincher version is available in 23mm, 25mm, 28mm, 30mm, and 32mm, while the tubeless-ready model trades the 23mm option for a wider 35mm size.

Whether you’re chasing speed on smooth pavement, exploring mixed-surface routes, or just trying to avoid spring pothole season, there’s probably a GP 5000 setup that fits your riding style.

Swing by the shop, and we can geek out over tire options and find the perfect match for your bike and the kind of riding you do most.
