Seraph named bundle: frame, fork, seatpost, handlebar, spacers, headset and thru-axles; TanTan also offers a no-handlebar selection, so confirm the chosen option.
International_price_reference
Seraph US$629 and TanTan US$579 displayed on 2026-09-22; options differ and no mainland delivered CNY quote is established.
Frame_weight_conflict
The earlier 953 g value remains attributable to TanTan; current Seraph differs by 30 g without a documented explanation.

Current 32C T47/UDH listing retained separately from older BSA and separately titled 35C New-Version pages. Seraph now states 983±50 g while TanTan states 953±50 g at the same nominal basis; this is unresolved. Prices are foreign storefront references, not mainland totals. Public discussion links the 35C page but does not establish equivalence.
