Cinelli Mini sub 8 Aero extensions

Cinelli mini sub8 tri bars are fairly unique, although something of a mixed bag. As their name implies, they're miniature extensions of the Spinacci mould legal for triathlon and ideal for smaller riders with shorter torsos. However, incompatibility with anything but ultra traditional bars coupled with a sizeable price tag overshadows their impressive rigidity and solid build quality.

Tried and tested 6061 aluminium brackets combine rigidity and strength while using lighter 5074 and a “techno polymer” rubberised bridge saves a few precious grams. Black anodising is described as matt, closer to satin by my reckoning but most importantly,doesn't clash or look out of place and seems hardy enough. Mounting them aboard the bars is something of a juggling act so remember to keep a long handled 5mm Allen key at the ready.

The trick is to position everything finger tight, tweak slightly, check alignment and tweak again as required. If you’re the sort unable to resist mid ride roadside fettling then carry a longer, single Allen key as those typically found on pocket tools lack the necessary gusto.

Broad shouldered riders may need to forgo the polymer bridge and set the extensions further apart but remember to cap the ends (Audax and/or nocturnal types may be pleased to know these will accommodate LED types for additional night-time safety). The convenient, if slightly unusual Velcro armrests are surprisingly comfortable, even over long periods and the extensions are impressively rigid, inspiring confidence when descending and even cantering up the climbs, heaving provocatively with all my might couldn’t cajole any discernable whip but those nearing the ninety kilo mark may well sing a different tune.

Verdict

Clever mini extensions better suited to smaller riders and traditional road bars
