Back in January (2018) I bought eTap now it's great stuff and I'd recommend it to anyone...it's THE way of shifting gears.. ! tho never used di2 but for me the sram stuff appealed more..
Anyhow on with this heads-up..
So i've rode it quite a bit and the batteries last well.. Fitting was easy but taking your existing stuff off and fitting the eTap is a biggish job..but once done it's fine.. I noticed it's the exact incremental adjustments that get the shifting absolutely perfect !
So, about a month back it started to hesitate moving from (1st gear is the biggest cog on left for reference purposes) 4th to 3rd..and that was it, so I'd keep riding it as it was very slight..then it got more often then freezing a fair bit and getting stuck in a hard gear is quite a deal ok the front still worked but mostly I'll spin + 85rpm so going to 60rpm is big..
So I contacted chain reaction and they said send it on on warranty - this I was against as it'd mean taking it all off the bike..so I contacted sram in the US and they said contact the importer who're Zyrofisher and they recommended a local shop via a shop finder which are called Sram Service Centre's - they said 'Yes we'll look over it, tho it'll cost.. Now I thought, hold on, this gear set is in warranty and maybe the guy wasn't fully up to date on the policy so I took the 'bang' to send it back - all of it to CRC - cost me £30 and now I understand Zyrofisher have it.. CRC emailed me and told me that if it's at fault, they'll refund the postal charge for sending it to CRC.
Soo, eTap; it's great !
So I've spent more than a grand to effectively NOT use it...
BUT realise what I'm going thru/experiencing..as after service is fire in the UK.. ie once I had to contact Speedplay to have them send me some cleats as they failed yet the UK importers said NO or Stages in the US had to step in as the UK importers wouldn't play ball.. What is it about UK importers ?? in the cycle industry..
