Review: Norco Threshold 105

At this year’s Sea Otter Classic in April, Norco expanded its cyclocross offerings with a full redesign of the Threshold carbon line. I tested the base model of the series, which has a bright green and black graphics that drew looks wherever I rode.

The test bike is smartly spec’d for its retail price of $2,645. Shimano 105 10-speed shifters and derailleurs are mated to an FSA Gossamer Cross PF30 crankset and SRAM chain and cassette. Sometimes mixing this many brands can backfire, but the shifting performance was as good as I would expect from a bike at this price point. The cleanly run internal cables should keep shifting well for many muddy rides to come.

Norco claims the bike uses frame-size specific tubing thicknesses to try and keep the ride characteristics consistent throughout the size range. I am curious to know what weight is recommended for each size as riders’ height-to-weight ratios can be quite varied. Riders who are short and stocky or very tall and lean may find the frame too stiff or soft.

Norco implemented thru axles at the front and rear hubs to add lateral stiffness and eliminate rotor rub caused by hub flexing. In the stopping department, Hayes CX Expert cable discs are post-mounted with 160-mm rotors, with the option to downsize the rear to 140 mm. Braking contact comes on quite quickly with decent modulation, but watch out on slicker surfaces. The point of lockup is harder to judge than with hydraulic models. The rear brake is tucked safely away on top of the chainstay, but the upward-facing cable exit from the frame may require some routine maintenance if water and grit find their way down into the continuous housing, causing unwanted friction. A rubber boot at the entry point may address this potential issue.

The stock Clement Crusade PDX 33 tires actually measured slightly larger so be warned if the commissaire comes around at the start line to see if the tires are regulation width. The compound is soft and sticky so if you will be doing some pavement riding before you head off-road, switch out the tires to save them for their intended purpose. Traction off-road was not an issue; even on climbs on wet grass, I could hear the tread just tearing up the turf under power.

A simple chain keeper is bolted on to reduce the chance of a dropped chain. Keepers are becoming more common. It’s nice to see this one nicely integrated into the design as it helps to protect the frame’s carbon fibre. There is a well-placed metal chain-suck guard moulded into the underside of the chainstay, wrapping nicely around to protect that area as well. The barely noticeable fender and rack mounts, as well as dual bottle mounts, make this a versatile machine that can be pressed into commuting or light touring duties. Overall, the Threshold is a good performer that might leave you with enough of a budget for a spare bike for the pit.
