I'm very happy with my purchase.
Everyone in the shop was very friendly and polite.
I don't have the person named who served me. But he was bc very very kind.
Thank you all.
I love the service. We were well attended to in hanging the handlebar tape. I like how the mechanic advised re cables and had it re routed. Also advise on the chains that are on promotion!
The chain was still in good condition despite a 427km ride. I bought a second chain and highly recommend it
Solid store know what they sell, strongly recommended!
Good quality and have a clean cut on the wire housing.
Awesome communication from the team at NEC, and incredibly fast shipping. A+
Order arrived on time.
They’re very knowledgeable on parts n very patient
Upgraded to the Ergon SR Sport Men saddle for my road bike and the relief is immediate. The flat profile suits a forward-leaning position, and the deep relief channel eliminates soft-tissue pressure on long rides. Excellent power transfer without the numbness.
This is a good bell, easy to install.
The staff went above and beyond. They not only helped me install my bike lights and explained the different helmet options, but also adjusted my saddle to the perfect height. I was truly impressed by their professionalism, patience, and genuine dedication to helping customers. Thank you for such excellent service!
