The fact that the current generation of Shimano's Tiagra groupset has received comparatively little attention is mainly due to strong competition from within the company. Bikes with complete Ultegra or 105 equipment are sometimes so inexpensive that even keen calculators see little need for a groupset below this. The Tiagra, which has been on the market since 2007, is definitely worth a second look. The surface finish is significantly more elaborate than that of its predecessor, and the impression is correspondingly high-quality. Technically, it offers all the important features of the more expensive groupsets: ergonomically shaped shift brake levers, smooth-running dual-joint brakes with angle-adjustable pads, a state-of-the-art bottom bracket with bearings positioned next to the housing. What the groupset lacks in comparison is a tenth sprocket on the rear hub.
The economy combo performed valiantly in continuous use. After riding two Tiagra groupsets over a total of 9,500 kilometres in everyday use and training, we have nothing but good things to say. Apart from a rear derailleur that was destroyed in a crash, both groupsets worked perfectly the entire time despite minimal care and maintenance. At the end, we only needed slightly more force to brake than at the beginning; the shifting worked almost like on the first day and the gears engaged precisely. The bottom bracket bearings ran cleanly and without play, and the sprockets and chainrings showed no major wear. Only the Tiagra hubs, which completed a total of 2,500 kilometres on one of the two test bikes, were clearly inferior to more expensive models. Even when new, the balls in the bearings were running rough, and this finding had increased significantly by the end of the test, especially on the rear wheel.
Conclusion: If you don't mind an extra 350 grams of weight compared to the Ultegra, the Tiagra can also be a good choice for sporty, ambitious riders. It is also recommended for riders of older Shimano nine-speed groupsets who are looking for replacements for worn parts.
