Purchased my first road bike. Read the instructions that came with the bike on how to set this up. Even watched the YouTube video they send out about setting up your bike... attempted to adjust the handle bars with the hex key & instructions provided. Contacted Tredz to state that this could not be achieved. They asked for a photograph of the screw heads and then said I'd used an Allen key as opposed to a star key/torx key and that had rounded the heads and because I'd used the tools THEY PROVIDED and not this star key/torx key never previously mentioned this wasnt covered under warranty. It was clear from speaking to the initial customer services advisor that this was somehow going to be the customers fault and it took all of 3 minutes post conversation for the bike specialist to confirm as such in a snotty condescending email. Poor service. Poor manners. Genuinely wouldn't purchase/deal with Tredz again. 1st time. Last time.
