@submarined, sounds like you’re where I am. Currently hovering over the buy button on Marley 275 full builds at £700 for my kids. Eldest (almost 11, 154cm) won’t be tall enough for even a small Ragley for ~6 months and even longer for my youngest, but I’m still tempted to buy now and stash away. Unsure how much longer deals like these are going to be around if the bike market returns to any sort of normality.
I see reach as 415mm on the small Marley 275 full-build – I suspect they’re 2022 frames rather than 2023 frame-onlys, unless CRC/Wiggle have they’re desciptors wrong (although they seem to match Ragley’s own website). That compares to 396mm reach on the Vitus Mucleus 26s mine have been riding since they were 140cm tall, so sounds ideal sizing.
I expected I’d buy used FS frames to build up as their next bikes, but a new decent hardtail is very appealing. If full suss then Winstanleys have small Marin Rift Zone 29s reduced to £1200. It’s a bit jump in price compared to a well-specced Ragley HT though.
