    PROJECT: Tracer 2 converted to 650b

    I can't believe I did this because I really loved my 26" Tracer 2 and the Haven wheels were fantastic, but curiosity got the better of me and decided to give the 27.5" conversion kit a try with some new 650b FLOW EX rims built on Hope 2 EVO hubs. Finally got it all put together tonight along with a new set of Hope M4's and must say it feels freaking awesome.

    I was really afraid it would lose the spunky playfulness of my 26" setup but after a few tight compression turns and a little curb hopping it feels better than ever. I'm yet to get it on my regular trail to see how it really compares to the previous setup, but early indications are very promising. Like I said, I had no complaints before, but at 6'1" it just feels a little more proportioned and seems to now have a little something extra it was missing before - this definitely feels like it could be the ultimate trail killer for me.

    The head angle registers the same at 67 deg but seems to toggle between 66 & 67 where before it would jump between 67 & 68. The wheelbase grew from right about 46" to and even 46.25" now and the weight is almost identical at 31.85 lbs (including dropper post and pedals)

    The conversion went so perfectly smooth and everything went together with the precision of a Swiss watch - no clearance issues at all with my stock Fox 36 Talas and Neo Moto 2.3's. I'll post a better update once i get some quality trail time with her, but so far it feels like it's going to be an AM beast!

    Nice!
    Just make sure the wheels don't contact the frame or fork crown. I would deflate the shock and fork and completely bottom them out to see if there are any interferences.
    Where did the BB end up?

    Weren't you going to try some Hans Dampfs? How do you think the clearance would be for the 2.3 HDs? I'm am very close to snagging myself a T2 and making this switch myself. I just want to be able to run a full true 2.3" tire.

    Thanks iRider,

    Just curious, I've heard a few people recommend checking the front bottom out clearance, but if the arch, lowers and thru axle mounts are all one piece how could arch clearance change? Or come to think about it, is the concern with the bottom arch or the top crown? Maybe I'm looking at the wrong spot.

    It is about the fork crown, not the arch. You can clearly see that you have enough space at the arch, but if your tire hits the crown while you ride an OTB is inevitable.

    OTB for sure. I guess ya don't realize a 160mm fork compresses that much when you're just looking at in in static position. That would really suck to stick a landing only to end up doing a swan dive because the tire bottoms the crown LOL. From what I've read it should be OK but I'll deflate the forks to be safe - thanks.

    The Fox 36 Talas does not have any clearance issues with the Pacenti Neo Moto 2.3's. I have heard others say that the Fox 36 will support just about all 650b tires, but I have only tried the 2.3 NM mounted on some FLOW EX rims (mounted up really easy and air-tight so far)

    Good job!

    T hi

    I was tempted to do the same on my bike. But as you know mine can't be converted. Keep us posted on how you like it now.

    Happy trails man. Lu

    Hey Lu, good to hear from you, I have had a few short rides, but so far it feels incredible. I still need to hit my local Fully Loop for a good comparison. Yeah, the G1 dropouts are nice for a little versatility. Lets ride again sometime. TL

    Sorry for the newbie question, but will all Tracer 2 frames convert to 27.5? I'm guessing I just need dropouts from Intense? This seems like a great way to try 27.5.
    Thanks

    I bought the dropouts from Fanatik Bike. You need both sides and the brake adapter. Just make sure the new rear hub is 12x142. Very easy to do the conversion yourself once you get the right parts. PM me if you need more specifics.

    Trojan, how does the super slack seat tube angle feel? By my estimates based on how the conversion changes the Carbine angles, with a 160mm fork the seat tube angle will end up a very slack 68.5 degrees. Do you feel pinched off at the hips while pedaling or find yourself riding the nose of the saddle more often? Also, the higher bottom bracket doesn't have you feeling too top heavy?

    I measured the before and after head angle as close as I could and they both registered 67 but maybe a half degree slacker according to the iphone Clinometer. I don't feel any difference at all with the seat tube, in fact I didn't find it necessary to adjust the seat at all. Although the BB is a little on the high side in static position, it doesn't feel any more top heavy as a result - I was very skeptical about that too but am very happy it is a non-issue for me. I really like it so far. Hope this helps.

    Sorry to be picky but could you measure the exact BB height with the 650B drop outs? I'm considering the conversion but really would like to know what the BB height is and I realize it's subjective to tires and fork.. Could always throw some offset bushings in to drop the BB again? Thanks in advance. Bikes looks great!

    Sorry for lagging on a ride report, but I finally got some quality time on the T2 650b this past weekend up in Big Bear. Mostly some twisty fire roads, but also quite a bit of off-trail mini freeride with some small boulder drops and stump jumping and finally a fast downhill banked quad trail for some speed tests.

    Not sure what to say, but for me the best trail bike just got even better with the conversion. I was very hesitant to do it because I really like a spunky playful bike and feel drawn towards every obstacle I can find and didn't want the bulky feeling that I get with the few 9ers I have ridden. Super happy to report that the bike feels as fun and lively as ever in the techy type stuff and jumps like a champ. The biggest difference I noticed is a more stable platform to crank on when grinding up a bumpy climb and a noticeably better roller on the short hilly pavement ride to the trail.

    A lot of people say the whole 27.5 thing is all psychological, but I know my T2 like the back of my hand and can truly get an "apples to apples" comparison rather than jumping on a brand new 27.5 bike. The reason I did the conversion is because I'll be doing most of my riding up in the mountains from now on and I wanted a bike tailor made for longer rides that can handle everything from XC to light DH - and I think I now found the perfect setup for that kind of riding.

    tmeyer - sorry I can't answer your question with an exact BB height because I left the rig up at the cabin, but I thought it was right about 14" - don't let that number fool you though. I was riding in 6.25" the whole time with about an inch of sag and couldn't tell any difference in a slightly higher BB - I am very conscious of a low CG and would blow up the experiment if I couldn't "drive" the bike the way I like to. Non issue for me.

    Heading back up for more fun as soon as the horn blows on Friday afternoon

    Thank you Trojans1993 for puting the time and effort and bring us your exprience.

    Though converting to 650b was not top of my list, you've very much made it so.
    Much of the trails me and the group are riding are very technical and tight coupled with a lot of short intense up/downs so a lower rolling resistance plowing capability without sacrificing agility is much appriciated.

    Cheers.

    P.S.
    The fact this conversion is even relavent is a tribute to the T2 and Intense.

    I see you're running a C-Giude vs a ISCG mount guide. Do you like the C-Guide better? I have a Tracer VP (no iscg tabs) and not much room for a regular guide.

    I'm not Trojans but I'm also running a C-guide on my Tracer VP.



    This was my second attempt at installation. The first one failed because I had installed it just a little bit too far rearward, so it was too close to the crank arms and I sheared it off when it bounced into the path of the whirling crank arms. The breakaway mounts meant very little damage, though it did get buzzed by the jockey wheels. Since installing it in this location, I've had good results with no more issues. My main reason for installing it was to stop the chain from eating my chainstay, and I think it is succeeding in that department. It also did quiet the bike down, and around here I don't drop the chain anymore or get ghost shifts. We don't have very rough terrain here, but that's all I can offer for experience.

    I'm happy with it, as I didn't want to run a full chain guide. My Tracer has ISCG mounts, so I could, but I didn't want the weight, etc.

    Trojans, thanks for your reviews on the 650B conversion. My next build will definitely be 650B.

    Thanks CTB. Yeah...I just want to cut down on all the chain slip, I don't have a problem with dropping chains, its pretty rough out where in AZ.

    I just liked the simplicity of the C-Guide and it barely even registers on the scale. I didn't really have a problem with dropping chains but chain slap was very annoying and the C-Guide has been perfect. I have had it on for about a year now at least and have pretty much forgot that it's even there other than the stoke of a near silent bike when charging the rough stuff - No issues and would buy another in a minute if this one ever breaks.

    Hey CTB - bike is looking good !!

    Thanks, Trojans. Seems my bike is always changing, as I'm back to my usual wheels and the latest tire setup compared to that picture. It's keeping me entertained until I pop for a T275, but that has to wait until next year.

    trojans1993 i noticed that in our before and after photos that you changed the travel to 5.75. is there a reason for this? i'm thinking about doing the conversion on mine and was just curious if there is a need for it.
