roughly $700 for this group with sketchy warranty vs another..........
Interestingly here in OZ you can get a SRAM mullet upgrade kit (Force shifters, Eagle derailleur and Force brakes) for the same price as the Wheeltop. Yes the Sram requires XD hub and Cassette to get the 10-52t. However, it enables a bigger spread of gearing, bought locally with Sram quality and support.
Makes for a tough choice.
Someone mentioned the wheeltop ability to tune individual gears/sprockets. I see the benefit of this, but I can imagine that once you start you never stop tinkering until it drives you made, whereas the Sram should 'just work' out of the box.
I'm interested in the Wheeltop, very interested, but I would have expected 33% cheaper than Sram electronic. I have an Xcadey power meter and top end Chinese wheels, both are great, the companies are great, but when things go wrong it still takes 2-4 weeks to xchange info and actually get any new parts from the time I raise an issue..... not necessarily the fault of the company but the geographical and communication logistics. I'm not complaining here because the products were somewhat cheaper than local mainstream alternatives...... and this is without talking about going into a local bike shop for help, and the look they will give you when they realise you have an unknown groupset for which nobody has been trained or carries parts.
All food for thought, I was super excited for the Wheeltop groupset, but the price has put a damper on that excitement.
