Anyone have experience with the TRP evo pros?

Early days for sure, but they are completely silent for me. I’m running the green race pads with 2.0mm galfer wave rotors.

Mine are also silent except for when they start out wet but the noise goes away once they are up to temperature. I use Hope 2.3 mm discs and sintered pads.

mine went 80% quiet suddenly, green hope pads and rs05e rotors, they squealed all whistler trip in the dust and now suddenly stopped, occasionally they do but for most times it's gone 🤷‍♂️

Yep, run them on 2 of my bikes. as usual, the blue pads are meh - using galfer Purple with r5 rotors.(the r5's do make some noise because of the cut outs)
But they've been great.

I have about 60 days on the Evo Pros.  It’s a solid iterative update to the DH-Rs, I have two of the old sets on other bikes.  Big change vs the old ones is that you now have a wider range of lever adjustment (much closer to bar) and a decent amount of bite point adjustment.  They still kept the low maintenance aspects.

As far as pads I run the red TRP semis, I drag my rear brakes too much to run stock organic blue pads.  Most of the TRP athletes seem to run the blue pad.

Be careful on the install, they reinforced the brake hose with a hard plastic liner that can get kinked.

I run the T4V4s with Trickstuff pads and Daechle HD rotors and they don't squeal unless wet.

Edit: I wasn't wrong but I haven't found them in stock anywhere in US apart from some obscure ebay dude.

BTI has both in stock now, so any US bike shop should be able to order them for you.

365 Cycles have GR4s and TR4s "in stock", below MSRP. Hmmm.

"in stock" == not really in stock. My order was cancelled after initial confirmation and "shipped" notification, don't order from 365 Cycles just yet.

When you break a Magura MT7 lever save the clamp piece, it fits the Hayes Dominion lever. You can’t go the other way as the MT7 wood screws don’t fit thru the Dominion clamp holes.

Anyone figure out how to stop the bleed ports of TRP Evos from leaking all the time. O-ring? I tried drying out all the oil from the threads before putting back in the screw, Tried teflon tape and it wouldnt hold.

Have really been enjoying my Lewven brakes lately. LHP+ levers paired up with maven ultimates. Still have that wall of power when you lay into the brakes, but much lighter lever throw and still good modulation. Ran them for a week at whistler with no issues and even sold a friend on the Frankenstein setup and he is getting the same setup for his bike.

i'd love to do Radic Levers paired with Hope GR4 calipers honestly, the Maven calipers are a bit of a pain to bleed + the pistons don't move as freely as the Hope/Trp Ones

If you pair TS or Radic MC's with maven calipers, it will result in a soft bite point and a TON of freestroke. Both TS and radic use a 9mm MC piston with no cam mechanism. I've tried a Radic MC with a Magura gustav caliper which pretty much has the same overall piston area as a Maven caliper. You either need to have the brake constantly rubbing or have the reach miles out to have a proper bite point.

I'm not sure what size piston the LHP+ MC uses but it's likely between 9-10mm. The LHP+ lever also has leverage adjustment which can be used to take up the "slack" that comes from the larger difference in piston area between the MC and caliper.

LHP should have a 9mm piston.

I have paired a LH4 lever with a Cura 4 caliper. With the bleedblock installed the bite point is really good but with pads and disc it get's worse. Freestrocke is not that bad with the freestrocke adjustment almost fully closed.

The Radic mineral systems have apparently been much less reliable than the DOT, even with the new seal material. It’s super frustrating, I’d spec DOT or buy something else.

Interesting brake set up! Anyone else have Maven/Frankenstein brake set up with Maven calipers? Waiting on a bike with Mavens and curious what people has done with different levers. I saw on other forums some people did Maven calipers with shimano levers? May have some trp dhr levers laying around the spare bin parts and would be curious how it would feel with a maven caliper.

Did they give you ETA? The-LBS.com mentions 3-4 weeks ETA.

Sorry, I meant “the local bike shop” not “The-LBS.com” a website called the LBS is cause for much confusion. 😆


BTI (the distributor they ordered them from) still says they’re in stock.


There’s a chance they land tomorrow. 🤞



Edit: anyone can view the BTI catalog. It’s super useful if you want to know what your local shop can order.

Yeah, I understood you, the name of the online retailer is just a coincidence. I am surprised that one of the major online retailers of Hope in the US has 3-4 weeks ETA if BTI has them in stock. I saw them "in stock" at Bikeman that would obviously get them from a distributor, but their odd descriptions and odd stock situation (some colorways only available as RH/R) was exactly the same as 365 Cycles. I am going to let this rest.

What do you mean by “terrible”, and what are you expecting to get from the power lever instead?

Way too curved. Wish they were longer. The tech 4 levers could been even longer imo

OK, the power lever will address that. It’s got less of a curve and is a bit longer (not by a whole lot, mind you…).
