kneejerk said:I did get a very good work out while riding those heavy rims up hill and on the flats (even). It just may be the training I need to turn around my mediocre road biking performances. I'll just get some downhill rims once I get back up to normal speed on the Freerides!
How wide are the 819? Im looking at runnign 23c slicks for road riding. I can maintain a speed of 17mph on my rize 4 with small block eights as this bike is lighter than my road/xc bike.Dan Gerous said:Mavic 819 are not very wide though. Notubes make light and wide rims, although they are not as strong as Mavics.
I like to freak people out. I have those 23cx559 tires on my XC bike with drop bars. I usuallly run 120+kneejerk said:with Mavic, that last portion of the rim # is the internal width of the rim, so 819 the 19 refers to the internal width, at that width a 23c would likely be too narrow, atleast a 25c would be the ticket, although the rim outer width may still stick out some and possibly contact the ground on aggressive turns, just keep the tire pressure ultra high to avoid deflection,
That would be one strange looking Rize 4!
You started out tubeless... Why go back to tubes? I'm 210 and last night I ran 26 front and 30 rear. For grip the lower the pressure the better. Running your tire in the reverse direction will = less grip for dirt. On pavement direction doesn't really matter and 40 should be adequate. Any higher and the applied surface area of the tire on the pavement is diminished to a point that high speed leaning turns will become slick.kneejerk said:I don't want to get pinch flats so I think 40 is right on for me now.
Try and adj seat post or a higher rise stem and or bar. I kept my saddle at my optimal climbing position, then put on a gravity dropper, then went from a 5 deg to 20 deg stem....kneejerk said:I just realized the reason Cannondale made the seat angle rather relaxed on the Rize 140 after moving my seat a little further forward for better climbing performance. It made a difference on really steep down hill sections, making the bike want to flip me over the top more.
