Perfect on line company

I ordered new shocks at TEC. This company is really great! Especially the e mails for routing the shocks and all the information. I ordered the shocks with DHL express. TEC informed me everything were the shocks were at the moment of sending to Holland. Great TEC company. Great service. Thank you dear TEC family! Best regards, Ruud. ( The Nerherlands )

Fitted the progressive springs, pre-load adjusters, cartridge emulators, and piggy-back rear shocks to my 2011 SE Bonnie.

Just did a 200km fang around some of North Queensland's country roads and I couldn't be happier. Rough and damaged road surfaces just ironed out and the whole bike just feels planted. Well done TEC.

Economical Upgrade

Very firm but controlled suspension upgrade.
The bike holds a good line on the road and smooths out rough road surfaces better than the original shocks that came with the bike when I bought it brand new in 2003

Rear Adjustable Shocks - Bonneville Spirit 2015 + Triumph Chunky Billet Alloy Fuel/Gas Cap, Silver

Having deliberated over which shocks to choose, decided on TEC (Thanks to Delboy's Garage & TEC videos and reviews)- Whilst accepting they will need time to bed in, the difference was felt straight away! - Original Triumph Shocks had only done 3,500 miles and began to noticeably fail. NB: Important to really ensure all paint and residue (where applicable) is removed from frame shock mounting pegs, as a very snug fit and if not perfectly cleaned, they will not fit!. Place some grease around clean pegs too as added protection. Delighted with appearance and quality build. Also purchased Chunky Alloy Fuel Cap - Really nice upgrade! Thank you to TEC for their customer email support too - Much appreciated - Highly recommend and great value! - Standard forks currently, maybe an upgrade here too!

All around great service and upgrade!

Great fast shipping, fitted both front and back myself within an hour. Instructions included but knew what I was doing but a easy diy job for anyone with a 22mm socket for the front forks.
Been out twice for 10 miles each to bed them in and the difference is night and day .
Feels like a newer more refined model now
Brilliant !
