Fulcrum has released three new models of its previously-budget Racing Quattro wheelset. In addition to updating the existing 35mm-depth alloy version, the Quattro range receives two carbon 40mm-deep models, including a disc version.
All three models receive a wider 17mm width (internal) clincher rim design (not tubeless-ready) to better fit with current trends. This isn’t considered overly wide by today's standards, but should help to provide more comfort and a better fit with 25c or larger tyres, while not introducing fitment issues with older, narrower frames.
The Fulcrum Racing Quattro LG
Weighing in at a claimed 1725g, the entry-level Racing Quattro LG (£315 / US$TBC / AU$TBC) gains a 4mm wider, 23.2mm (measured externally, 2mm wider internally) aluminium rim. This is claimed to produce a stiffer, more comfortable wheelset, while a new lighter freehub (Shimano/SRAM only) offsets any weight gain from the previous generation.
The Fulcrum Racing Quattro Carbon
The new Racing Quattro Carbon wheelset is claimed to weigh 1555g. Offering a new 40mm-deep rim, this model features a uni-directional carbon rim, including a 3K carbon braking surface that is said to feature ‘3Diamant’, a process that uses diamond tipped tooling to ensure a consistent braking surface.
The Fulcrum Racing Quattro Carbon DB (DIsc Brake)
Adding a few more grams at the hub for a total paired weight of 1605g, the Racing Quattro Carbon DB (disc brake) is a new option for road disc users. The wheelset features a 40mm-depth with uni-directional carbon across the entire rim, with no braking surface needed. Both carbon models are expected to retail for £1200 / US$TBC / AU$TBC.
Beyond the differences in rims, all three models use straight pull butted round steel spokes and aluminium nipples. At the rear wheel, Fulcrum sticks with its ‘Two-to-One’ lacing pattern and an oversized drive-side flange in an effort to balance spoke tensions. The hubs feature sealed bearings with preload adjustment.
Catering for the disc rotor and different forces, the disc brake version features 21 spokes front and rear, both setup with Fulcrum’s Two-to-One lacing pattern and oversized flanges. With this, the front wheel looks much like the rear wheel design, but flipped. The hubs on this model are said to be convertible between quick release and common thru-axle standards, including new 12mm standards. Fulcrum will offer this wheelset with either a 6-bolt or ‘AFS’ (centerlock) rotor mount. Interestingly, there is no mention of a disc-brake version in the new budget aluminum Quattro LG wheelset.
A brand of parent company Campagnolo, Fulcrum’s introduction of a race-ready disc brake road wheelset is an interesting one. Although Campagolo is thought to be working on disc brake options, these new wheels are more likely designed to suit an already booming market from SRAM and Shimano component users.
