PRODUCT DETAILS
The CORE Ultra 5 Carbon disc wheelset was developed for riding fast. Weighing only 1,338g, with a 50mm depth, these wheels deliver free speed that you will feel everywhere.
Designed and hand-built at our operations centre, the CORE Ultra uses an optimised carbon lay-up with tactical placement of T1100 fibres from South Korea, combined with Taiwanese ceramic bearings and Italian-made steel spokes. The CORE Ultra is our performance wheel range, proven to be amongst the fastest available, with data captured at the Silverstone Sports Engineering Hub wind tunnel.
Specification
The Wide 24mm internal profile (hooked rim design) gives you the option to fit wide tyres for increased stability when cornering, and increased speed due to improved rolling resistance - especially when ran as tubeless. With a centrelock disc as standard.

FREQUENTLY ASKED QUESTIONS
Where are Scribe / BEST / SILTMTB Wheels built?
ALL wheels under the Scribe domain are 100% hand-built by our master wheel technicians directly from our operations in Belfast, Northern Ireland.
We work with the best cycling manufactuers across the globe in the pursuit of offering our riders the fastest wheels possible with exceptional QC standards. As such, our supply chain is extremely unique. The carbon-fibre & bearings comes from Japan, the grease comes from Germany, and our hubs come from Taiwan.
We never hold back.
How do I quieten my Scribe / BEST / SILTMTB Wheels?
Most love the buzz but while we understand our hub designs may be slightly noisier than others. This is actually recognised as a sign of positive engagement. However, everyone within the Scribe Collective is different. So, if you're interested in dampening our freehub buzz, the tone can be muted by applying some of our exclusive MV1 Ratchet Grease
