The Exploro Road, cross, and MTB tires can all be fitted: 700c road or cross tires are close in diameter to 650b GravelPlus® tires. Switching to 650b wheels for wider tire sizes enables the frame to have compact, race-bred geometry and a short rear end, for agile steering and phenomenal grip on loose dirt as well as blacktop. Recommended wheels are 3T Discus for 700c, and 3T DiscusPlus for 650b. Exploro fits single and double cranksets and its ‘dropped’ chainstay on the driveside ensures there are no clearance issues.

Thru axle makes re-fitting a snap. Technology SQAERO® GO SLOW FASTER: the best gravel rides are long and grueling, so saving a few Watts is very welcome. Enter 3T's Sqaero shapes, squared-off aero shapes that are structurally efficient and fast. Sqaero shapes offer RealFast™ aerodynamics; they are faster not only under perfect conditions but also in the real world. Even when co vered by mud and muck. THAT'S RIGHT 3T's Sqaero shapes are designed to be as fast dirty as they are clean. The Exploro uses Sqaero 50/25, with a 50mm wide downtube perfect to pick up the airflow coming off a wider cross or mtb front tire and lead it on to the water bottles. The seattube is 25mm wide to make it aerodynamically disappear in-between the bottles and the rear tire. The headtube, seatstays and custom seatpost also use Sqaero shapes. GRAVELPLUS® The Exploro is designed to fit road, cross and even mountain bike tires following the GravelPlus standard. The road and cross tires are 700c, the mountain bike tires use the 650b size, ensuring that all of these have virtually the same overall wheel diameter and therefore the same predictable handling. PERFORMANCE GRAVEL GEOMETRY Exploro offers the most responsive ride ever on gravel thanks to its super compact performance gravel geometry: short 415mm chainstays and agile, steering ensure phenomenal acceleration and grip on loose dirt as well as asphalt. CLEAN PERFORMANCE Internal cables, hoses and seatpost clamp clean up the frame aerodynamically and visually. The FlipTop cable guide on the toptube comes in several versions to allow for mechanical and electronic shifting, with single or double chainrings. For mechanical shifting, the Exploro uses full housing through the frame to protect the cables from any dirt or debris. Prepared and Quality Checked Each Frame is fully prepared and quality checked by Wiggle's team of qualified bike mechanics to ensure your bike arrives in perfect condition.
