relatively small companies that sell a large proportion of their total volume as high-end bikes can’t reasonably be expected to keep large stocks of swing-arms and front-ends
Hmmmmm. Yeti, turner, intense, cove, ellsworth, transition (to name a few) all seem to sell predominantly high end full suspension frames in similar or smaller volumes than lapierre and santa cruz (certainly even smaller volumes than Lapierre and SC in the UK!) and all seem to be able to supply/sell replacement fron/rear ends to whoever asks and either has a warranty or no warranty but the money instead. (I leave orange out of this simply because the fs bikes are made over here and so i imagine they can get away with much holding a smaller stock of spares at any one time than imported ones because they can just make up few more locally if they have unexpected runs of snappages).
[edit] plectstomus, the OP is not the only person on here to have come up against this with a s/h lapierre: there was a thread about the same things a few months ago. I tried a search for it but iirc the thread title didn’t have ‘lapierre’ in it so having trouble locating it.)
