Fulcrum unveiled several all-new or updated wheelsets at this year's Interbike show, including two 27.5in/650b options.
The new Red Metal XRP 650b includes a similar feature set as the 29er version, such as carbon-bodied hubs with adjustable cartridge bearings, elaborately machined tubeless-ready aluminum alloy rims, and butted straight-pull spokes. Claimed weight dips a bit, however, to 1,525g (3.36lb) for what should be a lightweight but durable offering.
Coming in a lower price point will be the Red Power XL. This switches to a less aggressively machined rim without the tubeless compatibility, and heavier hubs for a claimed weight of 1,815g (4lb).
One sure thing on the off-road front, however, is the new Red Metal 29 XRP, which raises the level of performance significantly compared to last year's Red Power 29 XL.

Fulcrum builds this wheelset with a heavily machined and tubeless-compatible aluminum rim, butted straight-pull stainless steel spokes (in Fulcrum's typical 2:1 lacing pattern), and trick carbon-bodied hubs with machined aluminum spoke flanges and adjustable bearing preload.
Claimed weight is 1,635g (3.6lb) – 280g lighter than the old Red Power XL.
Road wheel options
Over on the road side is an all-new Racing Quattro clincher, built with a 35mm-deep aluminum for good aerodynamics and predictable braking performance.
Fulcrum utilizes its MoMag construction method for the rim – meaning there are no holes on the outer wall – so, at least in theory, it's airtight. However, Fulcrum hasn't shaped the profile for use with tubeless tires.
Other features include aluminum-bodied hubs with adjustable bearing preload, aluminum nipples, Fulcrum's usual 2:1 lacing pattern, and straight-pull butted stainless steel bladed spokes. Claimed weight is 1,725g (3.8lb) for the pair.
Other changes to the road range are more subtle. For example, the top-end Racing Zero aluminum clinchers get a more subdued all-black finish to replace the more ostentatious red-anodized look.
