What is a review "Verified purchase" ?

We can confirm purchases for the reviews expressed on a request by e-mail after purchase or when the customer has this review from his personal space.

If review is not marked as "Verified purchase", this does not mean that the author's review has no experience with the product may have given his review directly on the site without unique identification, or the product has been offered or paid.

The label "Verified purchase" lets help you judge the reliability of a review.
Used for 2 to 8 weeks
Switching between the old worn Shimano and B-Twin reveals the new to have a much noisier freewheel and a very clunky gear change by comparison.
