Bontrager Rhythm Comp wheelset and TR tires

Posted in All Posts by shiggy on the April 14th, 2007

have a little time on the wheels and tires.

Rimstrips were very easy to install. Tires (standard, UST and TR) easy to
mount and remove.

My weights:
rimstrips 45g each
valves 8g each
wheels (w/o the above and skewers)
Front 854g
rear 1051

Compares very well to my hand built trail wheels: Alex FD28 rims (28mm
wide), 14/15 spokes, alloy nipples, Hope XC rear and Bulb front hubs:
1071g rear, 895g (qr) and 872 (20mm) front.

The tension on these were much lower than what I expect. Disc side front was around 90Kgf and drive side rear ~100Kgf. I brought both up to ~120 after the first ride. After that first ride the rear was lightly out of true and dish. Front was fine
except for the low tension. The OSB does work well in reducing the
side-to-side tension differences. Much closer than with my conventional
wheels.

When mounting the TR tires I like to seat the beads before I put in the
Super Juice. Both the Big Earl TR ARC 2.35 and Mud X TR AR 1.8 aired up
nicely (to 50-60psi) and held air so I left them as is (no SJ) over night.
Lost maybe 3-4 psi so I let them sit another day. Still held the pressure
so I rode the Big Earls without using the Super Sealant. Not a problem -
except the BE is too big for the back of my hardtail. Rubs the chainstays,
chain rubs the sidewall in the lowest gear.

Replaced the BE with a Mud X TR 2.0 - which did not hold air overnight.
Added the Super Juice. Found it difficult to remove the valve core
quickly, cut too much off the SJ bottle tip so the tube would not fit well
and slopped a bit of sealant on the ground in the process. I will just pop
the bead loose next time. As I have noticed before it can take a couple of
days for the SJ to totally seal a TR tire. Not enough leakage (pressure
only, not sealant) to affect rides, though.

Love the look of the wheels. One of my riding buddies did ask if other
colors were available and was disappointed when I said no.
