I had a great experience from start to finish when buying my speed concept, every option was explained and I was confident in knowing I was purchasing the right bike for me , I would highly recommend Wheelworx .
There's a good selection to browse and the sellers give a decent appraisal as to the pros and cons regarding wheels and shimano 105 versus ultegra groupset. You don't feel railroaded into a purchase that is neither functional nor suitable for your needs.
The bike fitting, bike component overview, maintenance tips and future maintenance procedure was a real standout part of the customer experience.
Can't remember the chaps name (but he was limping due to a knew dislocation from rock climbing) but he was excellent. Top marks for him!
