Awesome levers to replace Magura MT5s

Decided to give Magura MT5s a go on my new bike. The MT5 levers were really inconsistent. They would fade during a ride. At times I would get on them and the levers would flex to the point that I would squeeze my middle finger between the lever and grip. I read that you could swap Magura levers for Shimano and use with the Magura 4 piston calipers (google "Shigura") and so I decided to give it a try.

Both use mineral oil and the Magura hyraulic cables fit the Shimano levers so the swap out was pretty easy. You will need to order the Shimano BH90 Hose Bolt and Fitting Unit (Olive, bolt and barb) as they don't come with the levers.

Man, what a difference. The XTR levers are rock solid. Totally different riding experience. Stops on a dime, no fading or inconsistency. Install and bleed was simple if you have the right bleed kit(s) and a hydraulic hose cutter.

Great ordering experience from Thunder Mountain. Ordered on Sunday. Shipped on Monday from Az. Arrived in NC on Friday. Highly recommend!


Exactly what I was looking for.
