Again, thanks for all the feedback!
Looks like we are going to offer 3 build types, one based around the excellent SLX groupo and the other 2 will be XT and X9. All with Thomson finishing kit and easton or Sunline bars.
The biggest challenge has being able to secure Shimano parts CHEAPER than Merlin sell them for! You would think i would be able to buy full group sets at wholesale prices from the USA cheaper than what Merlin cycles sell them for!
Really excited to be offering full builds with some really good savings, certainly cheaper than buying the parts yourselves!
