There are a ton of parallels between the Sentier 29 and the Nucleus 29 VR in the sub-£700 category. Both are the entry-level models in their respective range and both are offered in two different wheel sizes, where the 27.5in bikes come in four frame sizes (from S-XL) and the 29ers in three (M-XL).
Zoom in closer and you’ll notice that both also have tapered head tubes, threaded BB shells for improved durability, and internal routing for dropper posts. That’s not to say the frames are identical, however –
