Halo’s CNC machined track sprockets make perfect companions for production fixed wheelsets thanks to plentiful sizes, bridging the gap between the cheap, poorly machined if functional oval type commonly spotted on converted winter hacks and hand polished exotica costing the lion’s share of £60. However, competition is very tight at this end of the market and some specialist brands including EAI offer marginally better detailing for similar money.
Made from Cro-moly and available 13-20 teeth in one tooth increments, there’s plenty of scope for riders in hillier regions or even those fancying some muddy fun. The lager (17-20tooth) sizes are slotted to shave a few grams without sacrificing strength and look very tasty into the bargain. There’s a choice between classic satin chrome and vibrant colours (red, blue, purple and gold). These finishes could readily pass for anodising but are in fact a hybrid process known as electrophoretic deposition, sharing similarities with powder coating and anodising.
A chromate primer offering exemplary corrosion resistance is applied first, acting as a key for the colour and all the indications suggest these sprockets will retain their looks through the witches’ brew of salt, slush and other winter grime. Nicely cut right hand threads whiz aboard hubs with a lick of grease and there’s even the option of complementary or contrasting lock-rings but common or garden OEM models worked just fine.
Paired with decent quality chains, the bevelled teeth make for silent running, compensating for slight irregularities in chain line, so great for conversions although ours became progressively quieter with mileage suggesting there’s a short bedding-in period. Those prioritising weight over longevity are better served by aluminium but 55g won’t have most of the fixer fraternity breaking out in a cold sweat.
Great looking fixed sprocket for everyday riding
