TRP 8.4 mini V

I put these on a 90s Cannondale tourer as a replacement for the Shimano cantis. They have to be set very close to the rims, 2mm total clearance per the instructions. Any more clearance and the levers (6600) bottom out. There seems to be no way to open them up for wheel removal, can't pop out the noodle like on regular Vs. It's difficult to get deflated 32s through and I was planning to use larger. Any suggestions/ solutions from those of you who have used these or similar mini Vs?

the tight clearance is def the worst part of mini-vís

some adjustable noodles might help.

Thanks! They came with adjustable noodles that have very limited range. Guess I could see if there are some different ones available.

The noodle should unhook, but you need some slack to pull it out of that arm. My brake levers (Tektro RL520) have a button that releases the necessary slack. You have to figure out a way to get a little slack to unhook the noodle.

edit: try squeezing the brake lever real hard, then hold the Vs together with your other hand, then release the brake lever - at this point you might have enough slack to unhook the noodle.

Iíve got two bikes with mini-vís, and the window of proper adjustment is very narrow.

but like Tyrion said, you should be able to pop Ďem open. even if just barely

This device might be a solution: Shimano SM-CB90



Hands On Bike: Shimano SM-CB90 Brake Cable Adjuster

The squeeze, hold and release almost worked. Still about 5mm short. I may be able to get that out of the adjustable noodle so I'll investigate some more, thanks! What a pain.... Edit- yes! that Shimano adjuster looks like a great solution! Edit 2- ouch $17 each.

Oh yeah, it's really tight. My Campagnolo levers work great with these brakes, since there's a quick release button on the brake levers.

I just tried unhooking without the quick release. It did (barely) work:

Slide the rubber boot out of the way.
Reaching down from above:
Thumb along the inside of the noodle curve -- pushing hard outward.
Index finger of that hand pushing the top of the brake arm inward.
Two fingers of my other hand on the swing arm to help unlatch it from the noodle.

~~~~
Low profile pads
These work way better than the stock pads on wider rims. And the braking is less grabby.
kool stop thinline pads

They are long enough to hit my fork arms when unlatched. So larger than 35mm tires are difficult to take off the bike when fully inflated. (I'm not sure if the stock pads had the same problem.)

I cut off the tip of the noodle on my mini Vs so I can unhook it.

Update- apparent resolution I've used the technique hints provided and trimmed a few mm off the end of the noodle. Those, along with making full use of the barrel adjuster gives just enough slack to get the noodle out. I also found that I could set a little more rim clearance. Even though I can bottom out the levers on the stand, in practice the brakes are so powerful that about half the lever movement could lock them up. The rear brake uses full length housing and I spliced in a section of the new compression-less housing after the bend in the bars. I can't really tell much difference
