    Q on tires, gears, and more for 07 Hardrock Comp Disc XL.

    Hello,
    I am a Clydesdale @ 6'4" and 325 lbs. I ride a 2007 Hardrock Comp Disc XL bought new in 08 as a closeout with only stiffer front spring installed by LBS, higher-rise bars, and seat. Been a great bike for me. I ride mostly trail and XC but I am going back to grad school and will be using the bike for campus transport now. I ride about 2-5 times per week where I will occasionally jump things but am limited to my fat butt getting up to speed. The hard-tail fits me well.
    I am looking for some advice on decent Clydesdale-friendly tires that will hold up good for rocky trail, XC, and still be decent on pavement for campus riding. My stock rims have held up great to my occasional wild-hair jumping and I am going to ride them until they fail. I would also like to know if anyone has a suggestion for a better gear/rear-set combination than stock. I would like something less prone to kicking the chain off when shifting under power. I really don't use/need all the gears that I have now so less could very well be more.
    Here is a copy and paste of my bikes equipment from the Specialized web site:
    * A1 Premium Aluminum frame, disc only, double butted TT, ORE DT, externally relieved head tube, reinforced disc mount, forged dropouts
    * RST Gilla Plus RA Disc fork, 100mm, Cro-Mo steerer, 30mm stanchions, coil spring, rebound and preload adjust
    * Avid BB5 brakes, mechanical disc, 6" G2 Clean Sweep rotor
    * Shimano FCM-341-8 crankset, Octalink Spline, replaceable rings
    * Specialized/Alex HRD 26 rims, double wall disc w/ eyelets
    * Specialized Resolution tires, 26x2.1", 60TPI, wire bead

    I am narrowing down tire choices to the following:
    Continental Gravity
    Kenda BBG
    Kenda Nevegal
    Maxxis CrossMark
    MaxxisMinion DHF
    Any thoughts for a tire that will hold up to the high pressure I require that will be decent on rocky trail and XC but still okay for pavement on campus rain or shine? I have no problem running tubes as I haven't had so much as a single pinch flat with my admittedly limited jumping activities so far with my stockers from Specialized.
    I'm also curious if anyone who has ridden similar setups to mine could recommend an upgrade in the gear/shifting department that would be less likely to throw a chain when shifting and just better/smoother all around. I have lost my chain enough times now that I instinctively coast along until the gear change is complete to avoid ending up on the ground after peddling into no resistance. I don't expect to be able to put my full legs into peddling while shifting but I would like better than I have now. Any thoughts?

    Thank you,

    Shifters and dérailleurs...SRAM X.7 or X.9

    Tires...only ones I can comment on are the Nevegals. They will turn your bike into a tank however they are very slow rolling and probably would not last anytime at all on pavement. I run mine between 45 and 50 psi with tubes. No issues.

    I run these tires on mixed/XC riding for everything in my stable:

    Kenda Small Block 8's 2.1"
    WTB Nanoraptors 2.1"
    Panaracer Fire XC PRO 2.1"

    The Kenda, I've only run as a rear tire with the Panaracer in the front. The WTB's I have run front and rear on my bikes. The Kenda is probably the quickest rolling out of the bunch with the Panaracer being more aggressive than any in that list.

    Congrats on getting into Grad School!

    Thanks a ton guys. It is a real advantage to be able to bike around campus versus parking and walking/shuttle-busing. One of my favorite places to ride is on the drive home from school for me so I will be getting more "quality" ridding in too. Being able to use the same tires both places really helps to simplify things for me.
    I am leaning towards the Kenda small block 8 out of the original list. Any thoughts on running the Kenda H factors on pavement(campus) and dirt/rock(trails) with a heavy load like mine? I am doing some extensive internet window shopping right now and they all look good in some form or another. It is about "shut up and ride" time for me and it's all good.
    I am very lucky to be going back to school and on that note I had better get to bed like a good school boy.

    Thank you both very much,

    MOJoWales
