    2006 Titus Switchblade 650b Conversion

    If you want to truly want to assess benefits of going from 26 to 27.5, try a 650b conversion....if your frame/forks will allow. The transformation may surprise you. My 2008 Titus Switchblade was sweet as a 26er but it's even better as 27.5er. I was able to do the change without a weight increase due to extremely light 30mm wide Velocity Blunt SS rims....highly recommended BTW. My SB is now better in every category, handling has mellowed in a good way, less twitchy yet still responsive. The 26" "harshness" is gone! I've got a nice ride for a few more years....650b conversion is highly recommended for a Switchblade. Oh, took the opportunity to change gearing which also made a big difference. Went with 24,32,42 up front and 11 - 36 in back. BTW, Shimano's Shadow Plus technology is awesome, eliminated chain slap completely, the bike is silent, just a whisper from the jockey pulleys....way cool.

    BTW, If you do the 650b conversion.....you will be amazed at the transformation of you SB.....phenominal! Don't need a new bike....got one, and it's a really cool handmade USA ride. I get a ton of positive comments by all the Pivoteers in my area. Got people offering to buy it.....but it's not for sale Oh, I strongly recommend the Velocity Blunt SS rims....extremely light but strong.....made in the USA!

    What size shock are you running in the rear of your Switchblade? I have one that I want to convert but the rear shock is bad .

    2008 Titus Switchblade 650b Conversion

    @robertsmurray, I have the older 2002 switchblade that used the old rockers. And run it in 4" mode as I cannot find a shock that fits the switchblade in 5" as most cans are to large and don't fit between the rockers

    Haystack,
    The original TALAS Float R is an odd size of 8.25" long x 2.00" stroke wasn't holding pressure so I contacted Push about rebuild, they said they don't rebuild the TALAS Float R because parts are no longer available. So I serviced it with the standard Fox air seal kit which had all the seals except for one which I reused. Fortunately the new seals did the trick and it's holding pressure. However, I did purchase a new 7.875" x 2.00 Fox RP23 shock and I'm preparing to modify my rocker arms to accept the shorter 7.875" length. Actually I would prefer to find a set of 2003 Switchblade 7.875" Fox rocker arms, then I don't have to do anything. If you have a TALAS Float R, I recommend you throw some new seals in it, but check with Fox first because disassembly is different for the TALAS Float R....no wonder they don't make it anymore.

    The black rocker is what I have, the grey rocker is what goes with the new 7.875" x 2.0 Fox RP23. Do you know where I could find a set?

    DH_WP,
    I believe you can use a newer shock, you just have to flip it 180 degrees (head up). I just bought a new Fox RP23 7.875" x 2.00 which is a lot smaller than my original TALAS Float R. I'm preparing to modify my rocker arms to accept the shorter 7.875" length. Actually I would prefer to find a set of 2003 Switchblade 7.875" Fox rocker arms, then I don't have to do anything. Measure you shocks overall length and stroke and see if there is a new shock that matches, then install with head up instead of head down.

    robersmurra can your Talas shock stay down in the lowest setting? If it does (mine wouldn't) measure the i to i and it should be close to 7.875 same as the RP23.
    See how you like riding it with the this geometry (slacker and lower bb). That's what the RP23 would be like.
    I always thought the Talas worked backwards from what it should be. In the longer plusher setting (8.25 i to i ) the headtube angle was steeper and bb was higher.

    blcman,
    The rocker arms I have are for 5.5" travel with a Fox TALAS Float R 8.25" x 2.00". With a 27.5" tire the shock end rubs on the tire at about 4" of travel....not good. This is why I'm looking for 2003 Switchblade 7.875" Fox rocker arms. I have done the CAD work and it's also possible to mod (drill and bush) my existing rocker arms to retain the 5.5" travel with a Fox Float RP23 7.875 x 2.00" by moving the bottom shock mount holes .375" allowing for full 5.5" travel,no rubbing, same geometry....It's looking likely this is the way I have to go since 2003 Switchblade 7.875" Fox rocker arms no longer exist. BTW, my TALAS shock doesn't hold the reduced length setting either....no wonder it died years ago, it's also a PITA to service with new air seals. I have high hopes the RP23 w/Propedal will work well cuz I'm really liking my 650b SwitchBlade, surprisingly good....kinda cool too.

    Post up the results as there are a few SB out there with the Talas shock and link that could be rejuvenated.
    Have you tried posting in the Titus forum? Good luck with your mod.
