Bike Check: Maxime Chapuis' Specialized Stumpjumper

Nov 11, 2020
by Daniel Sapp  




Max made the switch to enduro racing from DH three years ago in order to experience more than just the DH track while riding. Calling Geneva, Switzerland, home he has an abundance of terrain nearby for training.Since the last EWS in Finale Ligure, Max took a good bit of time off to recover from his crash (video of that here), and hang around home with friends. After all, it had been a very strange season, and with the shortened schedule Max chose to leave it all on the track and go all-out rather than play it safe. Unfortunately that tactic didn't really pay off this time.

For the offseason, he has a few media projects in the works and is staying flexible to see what the schedule looks like next season. Now? He's just spending all the time he can on his Stumpjumper.

 After seeing the crash it makes me wonder why some racers still go gloveless. No matter the conditions, having gloves on give better grip. I mean if Sam Hill and the Bulldog wear them, I would think everyone else would..but what do I know, I’m not racing so I could be wrong. Ugh that looked like it could have been much worse.

 Ditto. When I get sweaty my hands get scary slippery on my grips. Gloves or GTFO for me (or GTFOTB more like it).

 I wish I wore gloves. I prefer the feel of no gloves, but buggering your palms when you crash sucks.

 Depends on the grips for me. I run a pair that WTB makes, they are very comfy to the skin and grip well for my dry hands. Ive used the Renthal kevlar grips and liked them but they did not feel good or grip too well without the gloves on.

 3weeks ago I ended up with 5 stitches in my right palm after tipping over clipped in and putting my hand down on a small rock. I brought 2 left gloves by mistake and decided to go without. The last time I went without gloves I had an open dislocation of my left pinky finger. I'll go with gloves no matter the weather

 keep it here on PinkBike, lol!! .....been ridding gloveless for over 12yrs...DH, BMX, whatever. The only truly annoying thing about not wearing gloves is that I constantly have to defend myself from that guy I just meet on the trail 15min ago. And, everyone wears gloves when they are super sweaty and when it's too cold. But don't start not wearing gloves, you may really like itWink

 @babathehutt: next time turn one glove inside out, it'll fit the other hand. Better than nothing.

 I think it is important to realize that not every hands sweat the same amount ... If my palms would not sweat like a monsoon rainstorm, maybe I would also ride gloveless.

 Yeah i just like riding gloveless. A vestige of my bmx days perhaps. If it's hot and I'm sweating a lot I wear them, if it's cold or raining I do too. I always race with them. If I feel like I can get away with it though on a particular day, the gloves are off.

 I'loved my Mt5 until the (rubbish plastic) lever broke after a really light crash 2 weeks ago.
Looking forward to the arrival of the xt levers and to go full Shigura!!!

 @paulomach: I actually really liked the "carbon" levers. Maybe not a problem in Brazil, but in Vermont in the colder fall and spring, having the lever be a non-conductive material helped keep my pointer fingers not-frostbitten

 @rbarbier12: definitely not a problem here!!!

 @rbarbier12: I’ve broken three levers over the past two years. Right at the pin that holds the blade. Even with them loose enough to rotate on the bar by hand.

But they are the best feeling brakes I’ve used. I can’t go back to sram or shimano.

 Best thing I ever did to my Maguras remember to use magura barbs Shimano olives Wink @paulomach:
  • 4 1
 @paulomach: I tried Shigura for a while. The spongy feel and inconsistent bite point isn't worth it/ Either swap out your stock levers for aluminum HC levers, or put the hc3 levers on your mt5(yes they're compatible, I have hc3 levers on my wife's mt5 brakes). Or even better, get yourself mt7 master cylinders. The biggest(only) difference between the mt5 and mt7 set of brakes is the master. The mt5 master is made of a cheaper plastic, while the mt7 master is "carbotechture" or whatever, which makes it much more robust. Once you try mt7s with the hc3 levers, you'll be hooked. The lever feel is firm, solid, and with a nice short throw, way better than pure shimano or shigura. Mt5s with hc3 levers perform good too, but they don't feel as solid, and they have a little more throw(still better than shigura/shimano). Even just HC levers feel better than shigura/shimano. Too many people judge maguras by the sh**y stock levers on mt5s. Swapping them out makes a MASSIVE difference in lever feel. Also, if you do shigura, you wont be able to use the "syringe vacuum bleed method" at the lever end to get that perfect bleed every time.

 @mtb-duke: for me shigura > MT7 definitely. More power, better lever feel and no more crappy plastic. I'm finally happy with the brakes after upgrading to XT levers.
  • 4 0
 @Unrealityshow: same here. I broke about 5 levers, right where the pin goes into the plastic (it's cheap plastic, not carbon or something!). Lost several riding days. Once it broke when my bike fell inside a postbus! The last break was the most frustrating: after climbing 5h to a 3400m pass in the Caucasus, right on the last meter, when the lever touched the summit pole. Had to push down the bike for hours ;-((
Shigura since then (slx levers are really inexpensive and robust), full shimano (XT) on my new bike. Never broke anything since.
  • 1 0
 @sofamac: I now have two calipers just sitting around, so it may be worth my while to try the whole shigura thing.

With that though, do you need a shimano specific bleed kit?
  • 1 0
 @mtb-duke: I’ve broken two MT5s and one MT7. Not any more robust. What you are calling the master cylinder is called a lever by Magura.
  • 1 0
 @mtb-duke: FWIW I much preferred the feel of Shimano levers to the stock MT7 levers. I had to try a couple versions though but I ended up using XT levers from 2 generations ago (forget the series number). However its true the need for more regular bleeds and the sometimes inconsistent lever carried over as these seem endemic to the Shimano system. However bleeds were not a problem at all, just bubble bleed once in a while never felt the need to vacuum bleed the top. In fact bleeding the combination was excellent becaues Magura has a nice screw in bleed fitting on the caliper whereas the shimano is slip fit and was always in danger of falling off.

My primary issue with Magura brakes which were otherwise excellent was there isn't enough pad rollback. I seem to have more problems than most with disc rub and these were worst than the normal Shimano. The drag was noticeable.

I hate to be that guy but I have moved to Hayes Dominion and they are the best. The MT7's might have a smidgen more power, but the Hayes have vastly more pad rollback, great feel, rock solid lever, and better modulation.

 @Unrealityshow:

No - I used my Magura bleed kit no issue when I swapped to xt levers. Easy swap but be aware that the shimano levers don’t come with the compression nut. Makes sure to grab those as well.

I was having issue with the mt7 levers. Never could get a reach or feel that I liked. Bleeding was too frequent and inconsistent results. Got to a point where I could loose power over a steeper /. Longer descent which was getting a bit dangerous

With the xt levers - I still find a really good amount of modulation, more consistency, and the stopping power that I always heard about with magura. Just wish it came stock like that!

 @Unrealityshow: just bought the shimano funnel for $5. Other than that I use the magura bleed kit. Works fine...
  • 2 0
 @Jshemuel: You basically just use a shimano barb, olive, & nut with the magura hose and caliper and that's pretty much it. If you've ever shortened your brake line before, it's the same thing. It's easy. I tried it for a few months, but I still prefer the mt7/hc3 lever setup. All these folks breaking their Magura levers just have their brake levers screwed on too tight. I torque it just enough to hold still, but no so much that it doesn't move right away in the event of a crash.
  • 1 0
 @Unrealityshow: I just never liked calling it a lever since it can be confused with just the lever blade. Have you tried under torqueing them? My brakes rotate on my bars upon impact. After a bunch of crashes between me and my wife, we've only had one brake break. I always keep a spare in the car. Just swapped out the hc3 lever blade to the new master and we were good to go.
  • 1 0
 @Plancktonne: It's decent and it has it's advantages(mainly that it doesn't break as easily and the power comes on fast and hard), but I just can't get past the inconsistent and uneven throw between the front and rear with shigura. Shigura also feels spongy when compared to the hc3 lever setup.
  • 1 0
 @mtb-duke: what's the advantage, qualitatively, in running maguras with shim levers versus the original levers?
  • 1 0
 @Jshemuel: The most common reason people run Shimano levers with Magura calipers is that they don't break as easily in the case of an impact. If you crash a ton, it makes sense, especially since Shimano levers are cheap.
Also, The servowave makes the power come on quicker and stronger(this might be a con to some as you sacrifice modulation.
I still prefer the hc3 levers. Less hassle overall. Shimano levers are just way too inconsistent. I like having my front and rear brakes feel identical. Identical bite point, identical lever throw. With the shimano levers, you'll always have a little more throw and flex in your rear brake lever vs your front. That just drove me nuts.

 A couple of years back Max turned up to a local enduro race in Wellington on his way to Rotorua. Had never seen any of the tracks let alone ride them. There were a few local pinners there - he smoked them all and came 1st. Legend

 When it says “clicks of rebound” and “clicks of compression”, does it mean clicks from open or from closed?

 Open.
  • 6 1
 It should be from closed, as that is the standard.
  • 2 1
 Does closed mean fast or slower? Harder or softer?
  • 9 0
 @dexterfawkes: closed is full slow and full firm.
  • 6 0
 Specialized's suspension tuning page says - NOTE: Damping recommendations described as "clicks" are always referring to the number of clicks counter-clockwise from maximum damping (dial turned fully clockwise/closed).
  • 3 0
 @panaphonic: thanks kind stranger
  • 1 0
 @jclnv: It is from closed because fully closed is always the same = consistent. If you counted from fully open some forks/shocks can have a few "dead" clicks where you can't get enough oil flow to actually activate the circuits and counting these dead clicks can result in inconsistent setup.
  • 1 0
 @i-am-lp: Thanks man. Doesn’t really make a lot of sense to me. I guess if you’re comparing like for like compression tunes but what if you’re on a different size bike with a different tune? Ultimately I think it’s pretty useless information.

 Now that the Stumpy and Stumpy Evo have practically nothing to do with each other anymore, it kinda bugs me that there's two very different bikes sharing nearly identical names.

 New evo stumpy is much closer to the old enduro than to the stumpy. So much so that it convinced me to just keep on riding my '18 enduro for a few more years.

 @schooledrider: the new Evo is nothing like the old Enduro. I have had both and they are very different on the trail.

 Air is a shitty medium for a spring. I don't care what you say. Show me any high performance off road vehicle that uses air springs...I'll wait. My boss just bought a KX450 that has an air sprung fork and it feels terrible compared to his other bike with coils. He is already looking into putting a coil fork on it. The ONLY benefit to air springs is weight. If you can get past that, the performance is far, far superior. Why do you think the industry has been chasing "coil like performance" for years? Cause COIL RULES!! That's why. Live in your ignorance all you want, but coil is better than air, PERIOD.
