KRob is a MTBR.com member and owner of the Stuck in the Spokes Blog. He has posted a nice review of the Pivot Mach 6 Mk2 on his blog which you can read here.

I left him this comment on his post which I’ll repost here since it’s a good summary of my feelings about the 2014 Mach 6 Mk1 I’m riding as my main trail bike.

“Thanks for the review KRob. I bought a M6 in 2014 partially based on your review. It has been a great bike for tight techy forest riding here on Vancouver Island.

 I ride my M6 for the spring and summer then switch to a SC Nomad Mk 2 for winter.

 Things I love about the M6:

  •  short wheelbase for TT size makes it very maneuverable it techy tight trails
  • efficient pedaling platform but doesn’t get hung up on tech features climbing
  • slack STA makes pedalling position good with short WB and keeps front wheel light for powering over tech in the saddle
  • our trails are very rocky and rooty the M6 takes all the pounding without complaint
  • 12 months of riding and the suspension is still quiet and tight….I have not serviced it yet
  • carbon has stood up to lots of abuse without issues

 All the things I didn’t love seem to have been solved in the Mk2 Mach 6.

 I didn’t notice the lack of stiffness Pivot has solved in the new version, but I am a middle aged enthusiast rider so I don’t push my bike as hard as a lot of folks might.

 This is a great do everything bike. From long XC rides to tough DH it can do it all. Unlike some of the other AM rigs it feels more like a burly trail bike than a mini-DH bike. Since I have to climb for all my turns I appreciate getting to the top fast and efficiently.

 I’ll be keeping my M6 long-term. I want to see how it does after 5yrs+. I suspect it will stand the test of time vs. whatever else comes out.”

Pivot Mach 6 Updates

The Mach 6 got an update:

  • the bike went Boost front and back [**sigh**]
  • more subdued graphics [like]
  • revised internal cable routing [like]
  • alloy version available [like]
  • stiffer revised linkages [like]
  • removable front dérailleur mount for 1x use [like]
  • updated shock [like]

All in all a good update. Kind of doesn’t matter to me much since I’m keeping my existing Mach 6 for many more years. The stiffer linkages are retrofit-able so I can add those to my bike should I wish.

Bike Magazine Pivot Mach 6 Review

Bike Magazine posted this Pivot Mach 6 review recently. I thought I would share.

You can read some additional printed info from their review here.

You can read my thoughts on the bike here.

Two points I don’t agree with the review are:

  • internal cable routing on this bike is lame in my opinion. It’s hard to use, finicky to setup and after all the bother it only”hides” 14″ of housing from view, but also leaves 12″ of exposed derailleur cable next to the rear wheel where crap will contaminate it. Definitely not awesome.
  • Due to the shorter TT and CS the WB on this bike is actually quite short for a 6″ travel all mountain bike making it a good choice for tight forest trails if you want one-bike-to-rule-them-all fleet.

My Pivot Mach 6…

Despite my quibbles with a few details of this bike I’m still quite happy with it after 10 months of ownership. For an efficient bike that can charge up and down our tight techy forested BC trails it would still be my choice if I was buying a new ride in 2015.

The only difference is I would buy a stealth black bike instead of the power ranger blue I own and customize it myself with less garish decals.

Light Bicycle Carbon Rim Review [35mm/650B/27.5]

Freshly built LB 35mm 650B carbon rims...

Freshly built LB 35mm 650B carbon rims…

It wasn’t too long ago the idea of carbon mountain bike rims would make my head hurt. But, as more and more riders were using them successfully I started to feel comfortable giving them a try. Of course the stratospheric costs of the premium carbon wheels [over $2K] didn’t compute. I stumbled upon a discussion about Light Bicycle carbon rims on MTBR. The cost was reasonable $200/rim delivered to my door all costs in. The customer service and warranty support seemed excellent so I took the plunge. $400 and 1 month later a box showed up from China with some pretty sweet looking carbon rims inside.

Finish detail...

Finish detail…

I’ve got a client who fabricates composite parts for the aerospace industry and I help them with their quality management system. So looking at a well made composite rim is a pleasure and the LB product didn’t disappoint. Appearance is certainly not the most important thing for a rim, but a company that can build a product that’s finished to a high level of perfection gives you some confidence in the fact they got other details in hand. The rims were straight and weighed ~412g each which is within the specification on LB’s product page. As a comparison the Velocity Blunt 35 is an aluminum rim of the same size/width and it weighs 555g.

Hookless...

Hookless…

This rim is a hookless design which is purportedly stronger and deals with rock impacts better. I haven’t test that out, but I can say this is the easiest set of rims I have ever setup tubeless. 1 wrap of Stan’s tape a a few scoops of sealant then the beads pop into place with a snap using 1 CO2 cartridge. No leaks or hassles. No burps or problems on the trail. I like it! 🙂

LB rim and Hope Hub...

LB rim and Hope Hub…

Brent at Velofix.ca built up the LB rims with Hope EVO Pro2 hubs and Sapim Race spokes.

  • Front wheel weight = 784g
  • Rear wheel weight = 912g

LB rims in my Pivot Mach 6…

These wheels were mounted in my Pivot Mach 6 + Pike rig and abused on our rocky and rooty coastal BC trails for over 5 months of regular shredding. At the end of that I gave them back to Brent for a touch up and he said they were still running perfectly straight. They do have a few scuffs and light scratches rocks, but nothing to be worried about.

Testing out the LB rims...

Testing out the LB rims…

How do they ride? There are two main benefits:

  • they accelerate well [lighter weight]
  • corner and steer precisely [stiffness and wide rim supports tire better]

Is it worth the extra cost?

That depends on how much extra. The difference between a LB carbon rim and a comparable Velocity aluminum rim is $100/rim. So that means a aluminum wheelset is going to cost me $700 using the parts I typically spec and a LB carbon wheelset will cost me $900. I would pay the extra $200 for the performance upgrade. If you asked me to pay $600 or $1200 extra I’d say forget it.

Interestingly I have spoken to riders with ENVE wheelsets that cost $2K+ who also owned LB rims and they couldn’t tell a difference when riding them.

More testing...

More testing…

I’ll keep rolling with these carbon rims and see how they hold out long term. I do know 3 or 4 other local riders with LB carbon rims with as much as 18months of use on them and everyone likes them as much as I do. I’ll probably get a wide 29er set of LB rims for my Krampus built up with Hope hubs for tours where weight is more important than bombproofness and ultimate traction/float.
