Us old types like to talk to someone rather than email that is why it's not a 5stat rating

I bought these shocks on the back of watching a review on YouTube Delboys garage and the reviews on TEC. They arrived within 3 days of ordering and now installed “very easy” due to lockdown and the inclement weather I’ve not put them to the test yet.

I recently bought a Bonneville with alloy cast wheel and the first thing I thought about it was that it had the worst suspension I had ever experience. After some research, I decided to go with these TEC progressive gas shocks.
I also fitted the progressive fork springs that came with shorter spacer for my bonnie.
The delivery was very very fast: I placed the order on Friday, and got my parts on the following Monday.
The install was smooth and easy also thanks to Delboy's videos - I do confirm it is important to remove paint on the pegs.
Improvement in comfort and handling is incredible. It went much beyond expectations. The bike doesn't bump anymore, the rear shocks are great and give much better feeling of the bike sticking on the road.
It is for sure the best value for the money on the market.
