Stromer uses different manufacturers for rims and hubs.<\/p>\n

In older models, such as the ST1 V1, 36 V \/ ST1x, 6 & 12 V \/ ST2, 6 & 12 V, a Formula DC71 hub with a 100 mm x 15 mm thru-axle is installed on the front wheel.<\/p>\n

Many models are fitted with rims and hubs from the Taiwanese manufacturer Alex Rims<\/a>\u00a0to the application.<\/p>\n

On high-end models, such as the ST2S and ST5 of that time, as well as the current ST7, you'll find rims and hubs from DT Swiss<\/a>. On the first two models, the lettering +STROMER- can be seen on older batches with DT Swiss rims.<\/p>\n

With the ST3 Pinion, and also other models delivered from mid-2023 onwards, alongside AlexRims rims, you'll now also see rims from Rodi<\/a>\u00a0with a hub from\u00a0Blackjack<\/a>. Blackjack belongs to the Portuguese company Rodi, based in Aveiro. Incidentally, Blackjack hubs are compatible with those from AlexRims.Source<\/a>)<\/p>\n
