Planet X a different beast now, explicitly following the Sports Direct model of snapping up defunct heritage brands and using them to label up cheap imported kit. Hence you can buy the exact same frames with Planet X, On One, Holdsworth, Viner, Tomac etc branding.
Still get the odd warehouse full of bankrupt old stock that they clear out (I reckon those Carnac shoes I got a pair of and they’re still selling are at least 10 years old), but not directly competing with the big boys and their steady supply of mainstream stuff.
CRC lost it’s edge the same time they screwed up upgraded their site, everyone’s long sick of their permanent DFS-like sales and I reckon they stopped being people’s go-to bargain supplier a while ago. Wiggle and CRC’s edge is in combining free postage with free Collect+ returns encouraging speculative purchases – Planet X charge both ways unless you have a big basket, and I’ve just bought a CX skinsuit from Evans knowing I may be spending a few quid to send it back only because no one else had it in that size for that price. They’re almost a mail order shop of last resort for me.
