Dia compe evo-v levers

[eephotog]

While grumping about how the dia-compe 287v and tektro rl520 levers were uncomfortable, I found references to a newish option from dia-compe.

I guess there's finally a 3rd choice for long-pull drop levers.

Interesting.

Quite the outward bend.

Wow, those are....unique.

I wonder if the bend it to help the finger reach the lever when on the hoods. It appears they had to make some compromises to be able to accommodate a long cable pull in a road lever. Notice that the "horn" on the front of the lever extends up quite high (because the cable anchor has to be further above the pivot to create more cable pull); and that top of the lever has a very curved "saddle" shape (the cable has to make an upward arc inside lever body to reach the cable anchor, so they probably made the curve radius as wide as possible to reduce friction).

The design constraints imposed for the long cable travel appears to have resulted in an unusual lever body shape, and I suspect some people's hands may not adapt to it.

Definitely, and I suspect these same constraints are why I don't get on with the other two levers on the market. Travel agents will continue to have a role.

These look quite a bit like the 1980s compact version I am now using on my regular road rim caliper setup. These are fairly narrow at the contact point between my thumb and index finger. They work well for my fused wrist.
But I know nothing of the brake type for you're use.
Good luck.

I think I'll stick with my Tektros. I don't think I'll like that bend.

I believe these are the same lever body as the 287s with a different lever blade only , been thinking of buying a pair to check them out. Not sure why this lever shape got invented.

I guess for old school style MTB drops that have all the flair below the lever so you end up with the levers pointing forward and not following the shape of the drops ?

Taking a look at the 287Vs, I think I understand the Evo-V shape. The 287V has a relatively straight lever blade. Due to the position of the blade pivot, there isn't much offset between from the fingers to the pivot when pulling on the blades from the hoods, which means the hands can't get much braking force (leverage) when on the hoods. One way to improve leverage is to curve the blades back, increasing the distance between the hand/fingers and the blade pivot. The problem with this is that it decreases how far you can pull the blades back before they hit the handlebar. Bending the blades laterally to the outside of the bar allows the blades to be pulled back further, so you can can get full blade travel (i.e. full cable travel). A bit of compromise, and maybe a little awkward to use, but it does allow a longer cable travel.

I have been thinking about this problem for some time and I think I am going to make some non aero long pull levers for v brakes. I like v brakes on big tire drop bar bikes but I don’t really like any of the levers , travel agents are okay but always feel like a band aid

Non-aero long pull levers are the missing link to make v-brakes and moustache bars play nice IMHO

Agreed, I would also like that set up. Me and a dozen other people probably

[tellyho]

I feel like I can get a decent housing routing with aero levers on the moustache bar. Where do you put your levers?

[coffeecherrypie]

Could a manufacturer integrate a travel agent style cable pull adapter into a more normally shaped lever?
