Good service
First time using this as i was using another plant based degreaser. Used it to remove all the lubricant on my ebike drive train to prep it was use of waxed chain.
Perform well as describe. I only need to use it 2x to get rid all existing lube n dirt.
Highly recommended
Got this to wax it and then replace it on my stock kmc chain on my ebike. Wax is the way for me than normal chain lubrication.
A bit hard to break the chain to my desire length but once i passed that stage, all smooth.
Performance was good and no more black stain on my socks or hands.
Excellent service
And great advice on bike safety
As always, service was excellent. Service staff were efficient and friendly. Thank you
👍
Did my yearly full bike service for my BMC road bike. When I picked up the bike it was like new. Nothing to complain about. Definitely a good value for price paid.
Comfortable, light, and great ventilation! Loving it so far.
Great item and comfortable
