Currently having a battle with ‘electronics2017uk’ who sold this fork:
https://www.ebay.co.uk/itm/Rigid-Carbon-Fiber-Mountain-Bike-26er-29er-Front-Forks-Mtb-Bicycle-Fork-E45T/222920677324
The steerer is all carbon so it’s a lovely light fork, but the steerer itself narrows internally beyond the top so once it’s just an expansion plug won’t actually fit (the wall gets thicker, so the internal diameter is too narrow). They insist that I can just “make it work” and are slowly increasing the amount they’ll offer as a partial refund if I keep the fork (started at £10 now £35, for a £60 fork) because the return postage will be “too expensive”. I’m not massively keen on drilling away at the inside of a fork’s steerer and then putting it on my daughter’s bike so I guess at some point the return procedure will eventually time out and eBay will step in.
Anyway: avoid this company, their customer service is abysmal even if the forks are cheap. Once I’ve wrangled a return out of them I’ll be after a similar fork so if anyone knows a reseller of these carbon forks on eBay that isn’t a disgrace to humanity, please say.
