Indulge me + any other luddites – What ‘gravel’ frameset with rim brakes?

    My brief for a perfect frameset at the moment is basically:

    Take an ‘endurance’ road bike (i.e. light, fast, but upright for desk jockeys wanting to do centuries)

    Add large tyres, ideally 35s.

    Add mudguards

    Add rim brakes, mini-vs/cantis probably for clearance around tyres and guards.

    Such frames do exist, for example my current singlespeed commuter (Charge Plug, no gears though) and the Gunnar Crosshairs. The Kinesis 4s comes close but I’m suspicious of how big a tyre you could get in there with a calliper and mudguards. Edit: Forgot to mention the Van Nicholas Amazon Touring – Ti with canti brake mounts.

    I’ve spoken to one custom framebuilder so far (Shand) and they basically couldn’t do a canti frame for me, he didn’t explain why (I admitted early on I was still window shopping) but I guess it means setting up a new jig or ordering new tubes specific to canti-brake frames.

    Lots of CX bikes on the market obviously but the bottom brackets are typically a lot higher than a road bike, and the geometry usually a lot more aggressive.

    Likewise lots of tourers, but they’re heavier, stiffer etc (I had a lovely Salsa Vaya for a while, just always rode ‘dead’ when ridden as a road bike).

    Anyway, anyone aware of any other examples?

    Charge Plug (the pink fixation is just a coincidence, honest!)

    Cheers.
    Cheers. BTW the bars weren’t perpendicular, I lied exaggerating how important brakes are and I scored another big word. Lol. Was pitch black though and some idiot had footed a pole about an inch of a top speed head on though. Guessing 40 clicks; life begins.
    They read like perfect brakes, about 20mm shorter on arms then current brakes.

At 5 cm inner diameter the pulley seems large yet as cheap to organize I will try such as it has been measured and should fit without obstruction to grip or drive. I would rather dual pivot but I don’t know any and if available can wait 6 months as this isn’t drilling nor altering the bicycle cable network; just clamping pulleys. Regardless of brakes she should get up and go alright. Final spinning a 53-13 after single rear stepping from 53-19. Hope this helps with your endeavour of rim brakes. I have perpendicular bent a steel handle bar from rolling into a street pole and nowadays I much like brakes that allow skid just in case.

    You need mini v brakes like these http://www.chainreactioncycles.com/tektro-926al-mini-v-brake/rp-prod34580

    This what I meant. I guess it easier to use dual pivot brakes and hang sidewards on dry days. Lol

    Liking cantilevers due to clearance.
    Not sure if dual pivot road calipers will fit tyre but will mock fit into another bike soon to establish possibly.
    Front guards not really required on this bike as frame copes with our weather.

    Was thinking of bracing brake cable loop onto fork and pulling pulley with handlebar cable to double the throw.  Seems messy upfront.   Might neat fit on rear using naked cable along toptube as location of pulley system and rear of toptube as rear brake cable attachment point.

    Just an idea.  Thought someone else might be able to utilize idea with similar short throw dropbar brake levers.  Could allow strong rear rim clamp and guards without expensive replacements.

    I know that’s on my wish list regarding a gravel bike.  2 half circular tubes with central outer attachments to accommodate 1.2 mm cable inside tube and at attachment.  1 motor car hose clamp.  Fork end unknown!

    At the risk of derailling the thread and turning it into my stock disc brake rant, it’s actually in crap weather that I value my rim brakes the most!

    I’ve been through 2 bikes and 3 different sets of brakes, all of which sounded god-awful in the wet, which just put me off riding those bikes in crap conditions. Whether that was specific to me or not I don’t know, but I’ve decided I’ve now spent too much time and money trying to find a reasonably quiet set of disc brakes, and have given up.

    People keep telling me it’s a set up thing, or a pad choice thing, or a contamination thing, or a bedding in thing, but my rim brakes suffer from none of this, all for the cost of a £20 set of decent pads. The local shops have struggled to sort it, and one mechanic even admitted he spent 50% of his time now trying to help people silence noisy disc brakes.

    I would LOVE to be converted to discs, but until someone can promise me a set that doesn’t seem to require a degree in Voodoo Witch-doctory to run quiet in all conditions, I’ll stick with rim brakes.  

    Anyway, rant over, I like rim brakes, frames still exist for them, happy days : )

     

    I used to hate the noise my disc brakes make in the wet but with a change in perception I have learnt to love it.

    As a general rule, the point where I am applying my brakes in such a way to make a noise is the same point that I would be using my bell to alert others to my presence. The majority of these occasions on my commute it involves a descent that in wet conditions results in me not wanting to move my hands away from the brake levers. As the brakes make such a loud noise in the wet it means that I do not have to use my bell so I am able to keep my hands over my brake levers and feel a lot safer as a result.

    I’ve one rim braked bike and one with discs. Both can easily chuck me over the handlebars if I squeeze hard enough and I don’t really notice any difference in effort. Modern dual pivot calipers are awesome, and I’d imagine the direct mount versions will be slightly better. If you do a lot of riding in crap weather and you value your rims then by all means go for discs and get a really nice wheelset but for most use cases rims do the job. If you’ve got the clearance long drop dual pivots can even work for light, dry gravel

    Yeah I’ve been banging the

    Yeah I’ve been banging the drum for rim brakes for a while, and also hope there will be a bit of a comeback. I’m guessing their ubiquity at the moment is partly ‘shiny new’ and part ‘easier for the frame manufacturers’.

    I struggle to believe I’m the only person for whom the drawbacks outweight the benefits. I heard two people on this morning’s commute whose brakes sounded AWFUL, can’t believe that’s worth the little bit of extra power, makes me wonder if lots of people have only ever experienced cheap rim brakes with cheap pads, and are therefore blown away by brakes that actually work. 

    Still, there’s still options out there, although the Seven is taking the p155 a little at £2,550 for a Steel frame only with no fork. Think the Van Nicholas is the cake and eat it option (light but versatile) and the Cross Check is the pragmatic solution (cheap, heavy, but versatile). I suppose the third option is just bodging a six speed cassette in the back of my current singlespeed, would probably end up lighter than a Cross Check build but with slightly less range on the gearing.

    I think rim brakes will have
    I think rim brakes will have a renaissance, like vinyl. Most people are better served by disc brakes but all that does is increase the appeal of rims to people who want to be different. See also custom steel and lugged frames. I could have easily bought a more flashy bike off the peg for what I’ve paid for the Layhams but where’s the fun in that? Or the soul? Then again, I still dabble in film photography so I’m probably a bit weird…

    That Seven Redsky they could

    That Seven Redsky they could have designed the fork/frame to take an even bigger tyre, shame really as if it could have got a 32/33mm under a mudguard it would have being an even more attractive prospect and a wider audience.

    You can see that the brake pads are not at their lowest point so around another 5mm in drop, the difference between getting a 32mm tyre plus guard and not.

    Pro teams have already been fitting 30mm tyres under rim brakes for the cobbled classics with room to spare for years on CF frames so whilst I get that the focus is now mainly on disc brakes there is still a market for rim braked frames/bikes that can take a wider tyre, particularly for audax, touring, gravel and commuting/general liesure riding.

    Oh man, that Redsky is

    Oh man, that Redsky is perfect! Just a shame it costs twice what the Van Nicholas Amazon, and for the money you don’t even get a fork… Lovely though.
