I'm struggling here, would it be completely JA to 650b this and pop a kid seat on it? Wayjay probably only has one summer left of kid seat riding and the mount for the one we have won't fit on my Tachyon (I'd just borrow parts from that to set up the Stowe). My other low cost option would be to put the seat on my SS cross bike but that doesn't sound to thrilling. Life will be easier when he's of sound mind enough to stoke the tandem.

edit: No I wouldn't want to kid seat this with 700's, the frame won't really fit really larger than 700x25 but with a 650b has clearance for a 38mm wide tire.

I have all of the parts except for brakes, the bike that's set up 650b right now is impossible to mount our Yepp kid seat on.

Wait, a 700c bike can be 650b with long reach brakes?

If someone on here did it, I'd probably like it. Since it was done by someone I don't know, they're a fucking idiot.

long reach as in 73mm brakes

not the traditional 57mm medium reach

of course ymmv but on the couple bikes we tried that on we found the braking power of the super long reach tektros to be lacking. just fine for a townie but far from confidence inspiring when applying even small amounts of ham.

Backed. I put R556s on a townie setup for sup and it's a brilliant bike that brakes fit for purpose. I also put long reach centrepulls on a salsa la raza and it sucked.

LHT 26" disc fork has a a2c that's not all that far off most road forks. clears 650x42 with room to spare. That's what we ended up putting on bro's soma 650 conversion. mullet life.

Sheeat, maybe I should find a kid seat that'll work on the Tachyon. Just sucks coz a) the seat we have is awesome. b) lil guy will outgrow it quick.

But since this is the dumb question thread and all, this is the seat...

I got a second seat tube mount jawn with it, we usually use it on the tandem. I was thinking about puting the second mount on the captain's seat tube and having him ride in the middle position when Amy's not along ala extracycle style.

The disc fork I'm running on the Tachyon would fit on the Stowe but it has about a 20mm longer a-c distance, that sounds awful.

edit: 33mm taller

I don't think those Tektro brakes suck nearly as much when the pads aren't shoved all the way down to the ends of the slots. I've a pair of noname 53-73ish brakes on my Trek (~60mm reach) and, despite not being v-brakes, they've got enough power to skid/stoppie the thing as well as modulate as nicely as any of my other brakes do.

I think EJ's in 1" land.

EJ, if you go with a new seat, the one up by the bars is good. With like a 29x2.0 slicks rigid setup and wide bar, it's my fav dadbike setup so far- and I've tried a lot.

yeah this is for real

they get some flex in them, but they do actually stop well if you pay the least bit of attention to keeping the pads reasonably close

a lot of road dicks come out worse in most conditions

Maybe compared to some Hayes road dicks or something but no where near as much powah as shimano, trp, or even avid in my first hand experience

with the right setup, including the use of thinline pads, a nice Tektro can feel like a slightly soft v-brake

STI levers really help, just like with mini-vs and especially road dicks

unlike those, long dual pivots don't have a MA mismatch — the extra cable pull soaks up the flex instead, makes for a very different feel

Allow me to clarify with the exact setup.

The Tektro R559 caliper was setup with good aftermarket pads with alloy carriers. High quality housing.
Pads were indeed maxed out in lowest position. Brakes felt ok but grabbing a fist full of lever created obvious flex in the caliper long after the pads had contacted the rim. While riding off road the relative weakness of the brake really announced itself to the rider.

It was replaced with the cheaper road Shimano R517 disc caliper and RT-56 rotor. Resin pads / resin specific rotor.

After a short break in period a big improvement in overall stopping power as well as feel was reported by the bikes owner, one of the other mechs, and myself.

Man I kind of really like the way the Tachyon is set up right now, ain't gonna steel parts off of it. Looks like Sheldon's kid did a 25 mile ride on a tandem with a short stoker kit at age 2.5. Waylon is going to be 4 in May, I'm just going to bite the bullet and get a kit for ours over the winter.

Looks take the better part of $600 to set it up right.

i wonder if compressionless brake housing would be enough to get things performing acceptably for those not using shimano in situations where these brakes would be the most desirous solution.

we've got an old bridgestone road frame at the shop with fender mounts i just may have to experiment with if i could get the dadgum seatpost unstuck.

Works just like a v brake but the arms are super wide. The funky stuff on the right side is essentially the same as a v-brake noodle and stirrup and then the cable going over the pulley makes the connection so it actuates both arms.

Purposely remembering that housing pushes when the cable pulls helped when I was staring at the brake trying to figure it out.

crowding wrote:
here's the front brake. Actuates like a v-brake, but the pulley lets you rotate the arms out until they become canti arms and clear bigger tires than a mini-v. Similar to cannondale's old "force 40" setup. I've done this on several bikes, it's always felt nice and solved bigbike canti shudder problems. Then I put it on the back because (a) I could (b) more room for the cargo (c) seeing some brake failures on .83 rides convinced me that once you have bags and racks to deal with, reverse mount is actually more wrenchable in the field

crowding wrote:
The MA is higher than cantis with normal straddle yoke (that's where the "force 40" name came from, supposedly 40% higher MA.) But not as high as a V-brake.

as it happens, it's a good match for current STI levers that pull more cable

I intend to find out for myself at some point this week but how well does it work with recent-but-not-new shimano levers (i.e. 4500/4600), how well does it work period, and how close do the pads need to be to work well (looks like they are pretty well away from the rim in the gif, but how is the lever travel with that?)
I love the stopping power of my mini-v's (90mm arm) but without a travel agent they need to be so close that a puddle of dirty water can cause a nasty scraping sound that doesnt slow you down but drives you nuts. The 84mm mini-v's I've worked on are a bit better in that regard, but still not the answer I'm really looking for.
