    Turner v Rocky Mountain

    Hi currently riding a Turner Burner 27.5....been a Turner rider since 2005 but really liking the look of the new Instinct and Thunderbolt...and fancy a change.

    Does anyone have any experience comparing the two brands Particularly DW link v Rockys Smoothlink.

    I guess the instinct is = to turner czar and the turner burner = thunderbolt .

    Really interested i how they compare in particular climbing as lots of folk say DW is the holy grail..

    Thanks CR

    Also anyone know the bb hieght of the 19 standard instinct as i can only ses bbdrop listed.

    Ta

    The reference for the Instinct BB drop is the radius of a 29" wheel, so right around 370mm (14-9/16") based on a 2.2" tire.

    One of the biggest differences between Rocky's SmoothLink and the linkage type suspensions (DW Link, VPP and Maestro) is the amount of chain growth and pedal kickback with suspension travel, the Rocky has a moderate amount of chain growth and not much pedal kickback with increasing travel, where the linkage type suspensions have more chain growth and pedal kickback.

    SmoothLink also has more linear anti-squat where the linkage type suspensions have an N shaped anti-squat curve with the minimum mid point around the recommended sag point, so pedal induced chain tension helps keep the suspension balanced around the sag. The Smoothlink doesn't rely on pedal induced chain tension to hold it around the sag position, there's less anti-squat with increasing rear wheel travel. This Linkage plot of a Pivot 5.5 anti-squat has the same characteristic as the Turner DW link. The Thunderbolt anti-squat curve is typical of all the current SmoothLink suspensions on the Instinct/Thunderbolt/Altitude/Pipeline, Slayer frames.

    The Smoothlink bikes don't need the chain tension to hold them at that sag position so they pedal very... smoothly. You just don't get any sense that the pedaling is influencing the suspension movement, it leaves the suspension able to react to the terrain, so it is active but not mushy.

    Ok...mm..so what holds the smoothlink at sag point..

    Rocky say they have increased anti squat this year....how do they do that keeping what appears to be the same pivot positions...
