    Michelin Wild Rock'R2 and Wild Grip'R2: initial impressions

    Since I havenít seen these tires mentioned here very often, Iíll provide some initial thoughts. This is based on one ride so far, so I'm still forming impressions. I mounted a Wild RockíR2 (front) and a Wild GripíR2 (rear) yesterday, both in the Advanced Reinforced flavor. Both tires are mounted on Stanís 29Ē Free Ride rims, with tubes. The RockíR2 is the soft Magi-X compound, and the GripíR2 is the harder Gum-X compound. The casing is a 2.35, and theyíre noticeably narrower than the Minion DHFs they replaced. I didnít weigh them. The 29er RockíR2 is a claimed 1,150g, (+/- 7%) and if youíre the type of recreational rider who weighs tires, these may not be for you. The sidewalls feel nice and burly.

    In the garage:
    First off, these are UST-spec beads, and are likely to have issues with NoTubes rims, or any using their bead design. I knew that going in, and hoped that my older rims wouldnít be quite as tight as the newer EX rims. I expected some difficulty getting them mounted. It wasnít easy, but manageable. Tubeless didnít work for me, though. I donít have a compressor, and the fit was too tight for the beads to slide easily. In fact, I had to pull the Stanís tape off, because the bead scooted a few inches of it, creating a crease that I didnít want in contact with a tube. I retaped with Gorilla Tape, which probably bought me a few mm of slack in the channel, although those rims have a pretty shallow channel to start with. I didnít try soapy water, but not wanting to mess around with that was one of the things that kept me from trying tubeless years ago. I still have a few inches of bead that isnít completely set on each tire. I inflated them to the mid-40s, and banged the edges of the tires on the ground, but they didnít pop. One worked its way out over night, so I went on my first ride today with the tires still inflated into the mid/upper-30s in the hopes that the last bit of bead would seat (it didnít).

    On the trail:
    As I mentioned above, I was riding higher pressures than I prefer and not riding mach chicken, but I still got a sense of how these tires work. The Magi-X compound is pretty sticky. Riding around my house, the front tire was making it rain sand and grit. Fortunately, that didnít happen on the trail, and they didnít feel like slow rolling tires, probably thanks to the GripíR2 in back. In corners, the RockíR2 hooks up every bit as well as a DHF, maybe even marginally better. The GripíR2 corners predictably. It doesnít hold like the RockíR2 or a DHF, but you wouldnít expect it to. I really noticed the lack of traction in steep loose climbs, though, and spun my rear tire out in three spots I normally climb without issue. I put this down to the high tire pressure, loose conditions (I should have geared down, but didnít) and forgetting I wouldnít have the traction Iíve come to expect. The last loose climb went well once Iíd adjusted. Straight line braking was a noticeable improvement from my worn DHFs. I still feel like a DHR2 brakes better. On trail and dirt roads, they felt like they rolled really well. It was only once I was on the exit route back to town that I felt the tires rolled slowly. I can deal with that, and I like the way they hook up in turns.

    The jury is still out, but the initial impressions are favorable. Down the road, I think Iím likely to move these over to another wheelset with MTX-33 rims (after I replace a rear hub), and go back to Maxxis rubber on the Stanís rims.

    Good review. Have you always ridden with a DHF up front? I'd be curious to hear if you have any time on a Hans Dampf, High Roller 2, or Butcher to compare them to. These are at the top of my "to try" list.

    I've had DHFs in front for about a year, putting them on as soon as the 29" versions came available. I've had a DHF and a DHR2 in the back. I prefer the DHR2 there.

    I haven't tried the HR2 yet. I know a few people here who are really fond of them, but for our loose/dry conditions, I think I'd rather have a Minion. I was excited for the Butcher, but I lost interest when I saw it. The knobs are pretty small compared to the Minions, and for what I want out of tire of this class, it seemed like there were better options available. I might try one eventually, since Spec tires are cheap. The Hans Dampf? Well, I pretty much agree with most of the comments in the threads you've read recently. It's a big casing tire that grips predictably at intermediate lean angles, and isn't that great past that. The edge knobs are too small, not supported well, and wear unacceptably fast. Maybe I'll try the Magic Marys when they finally release the 29ers, since I'd probably put them on my Hulk wheelset. That'll see less use and the tires will last longer.

    Thinking about the problems with the HDs, Pinkbike recently had photos of a new Maxxis prototype that looks interesting.

    Yeah I liked the HR2 when you leaned the sh!t out of it but it's hard to get as far leaned as it needs to be sometimes. I also liked straight line braking a lot but intermediate lean was no good. I liked the Dampf but after 60 miles I was tearing knobs, not cool.

    Looking forward to hear how they mount up on the MTX 33 (i.e is tubeless possible?). I'm running 2.5 DHF's (F and R) and their width limits tire clearance in the rear. The 2.3" Maxxis Exo's just aren't big/burly enough for Albuquerque rock.

    I mounted another set of Michelins on a Bontrager rim last year. I though Michelin had produced some 28.5" tires :|

    Michelin Wild Rock'R2 and Wild Grip'R2: initial impressions

    I mounted the Rock'R2 on my MTX-33 front wheel for 48 hours, actually. I was waiting for my other rim to dry off after my first attempt so I could retape it. I was hoping it would stretch a bit (not noticeably) and it was ready to go if I wanted to get out before mounting the rear.

    The MTX-33 was a little easier. I've never tried tubeless with them, because I have a low tolerance for tinkering with it, and EVERYTHING I've read on these boards is that with these rims, tubeless is unpossible.

    I went with the Rock'R2 front and rear. MagiX front, GumX rear. My impressions as a front tire are similar to yours, although the MagiX front is still throwing pebbles and small sticks at my face after a dozen or so rides. In back, it has the best climbing and braking traction of any tire I've tried. I can shift my weight noticeably more forward on steep climbs without losing traction compared to the Ardent and Nobby Nic I had previously on the same bike.

    Any impressions on cut resistance vs. Maxxis 2.3 Exo tires? Cut resistance as in resistance to being cut by rock strike cutting through tread and/or sidewall (have had both happen on 2.3" Exo but not 2.5" Exo BUT 2.5" is a damn tight fit in my frame). Weights put the 2.35 Michelin heavier than the wider 2.5" DHF.

    Michelin Wild Rock'R2 and Wild Grip'R2: initial impressions

    Yeah, I believe they are heavier. I didn't weigh mine, as I mentioned, but I did weigh a DHF and posted in the 29er tire weight thread last summer. It was a bit over 1kg, less than the claimed weight of the Rock'R2.

    No experience with cut resistance yet. I'm nursing a sprained wrist, unfortunately. From the way they feel, I'd expect them to hold up as well as an EXO casing, and better than SnakeSkin.

    Do you happen to have an actual width measurement? If I recall correctly, knob to knob on my 2.5" DHF's were 64 mm and my 2.3" HR II's were ~58 mm. 2.3" fits my frame well, not so much on the 2.5's.

    Thanks

    64mm DHF sounds right. I came up with 63mm but haven't ridden them yet (although they did stretch overnight) and I may have squished the knobs with my calipers.

    No, sorry. I don't have any calipers.

    Bummer. Thank you for all the other good information you posted. I think I'll just have to order one to find out. If I can run it sub 27 psi without cuts from rock strikes/rim pinches, I'll be happy. If it's sub 60 mm width, it should fit nicely in my frame.
