Personally, I don't understand why the manufacturers continue to put the caliper on the back of the fork.

My Brooks Flyer tension nut was unwinding so I would have to adjust it after every one or two MTB rides. I wired it up and haven't had a problem since.MichaelB wrote:Was even thinking about some method of lockwiring, but will read the article and have a ponder, and check it before each ride .....
However, I don't think the skewer problem is an every ride occurrence for most people. I only look at mine occasionally on the rigid MTB. I might mark the non-clamp side to see if it is unscrewing on that side.

There is a lot further from the front of the fork to the brake disc than the rear, considering the fork is thick and the dropouts are usually on the front. Having posts 50mm long (for example) to get the caliper out enough will cause a significant amount of flex on the posts. It would probably have to be a solid piece and even then it will be fragile being stuck out in the front of the bike!rkelsen wrote:Personally, I don't understand why the manufacturers continue to put the caliper on the back of the fork.

the mosso is actually lighter than my older spesh hybrid carbon fork with cantis, and no more harsh. guess the triple butting actually works. played around with a white brothers carbon 29er fork a mate handed down to me, but it was suspension corrected and the handling was actually a little scary. theoretically longer trail and slacker headtube angle should make for lazier handling, but holy crap - twitchy twitchy twitchy.
certainly needs some bedding in right now, but suspect i'll run out of grip on the road long before i run into problems with lack of braking power. knocked 11mins off my 34km commute today! no significant problems with flex or regrets. i think i will almost feel a little sorry to head back to the old workhorse for the daily grind.
c'mon old timers and UCI sympathisers - get with the times and do it. the 2 extra grams isn't going to slow your sprint to the cafe, and may get you there with more skin. might make you more aero, too!

The Mosso fork seems to work quite well so far, especuially given that it's only $65 landed !!!
Did a commute to work this morning. Live only 5km the short way from work, but made the ride 37.5 by going via Mt Lofty and down Greenhill Rd. Yeehah

No lockers or undercover or anything so I hid it behind the door to the yard and locked it to a sign post!
And here is the obligatory garage door shot.

Mind if mention the $$ it costs ?
Is yours the 3 Disc or 4 Disc model ? What's the difference ?

Both the Konas are steel frames and have braze ons for fenders and panniers (needed and wanted respectively) until I found the SKS Raceblades in <32mm tyre width. I am just going to get a Topeak beam rack or similar if I end up needing panniers and I have the clip on fenders so I am happy.

Hey I worked out what the N45 was on the fork - its in relation to I think the lower bearing diameter (basically its the standard size..)MichaelB wrote:That's good value for $1700

Thanks for sharing this James.
I believe looks is the main reason why bike manufacturers use 160s on front and back (could be cheaper too due to volume) but you may be better served with a 180/185 on the front and a 140 on the back. Or at least a 140 on the back. A good 160 should be too much braking power for the back brake once bedded in properly.

I hardly use the back brake even now. Heaps of power on the front. The disc setup has supremely modulation so I am not worried about locking up. Unless I want to!

...Must visit the local frame modder this weekend and enquire about some welding.

There was a picture of a fixie with a rear disc a week or so ago. It had the caliper welded in between the seat stay and the chain stay, rather than just on the seat stay. Looked to be a good idea for bikes that weren't designed for rear discs.Jacobite wrote:...Must visit the local frame modder this weekend and enquire about some welding.

Yes, but according to one of the links you posted, lawyer lips don't necessarily do much if the force is great enough.cobba wrote:MTB forks have 'Lawer Tabs' as a backup to stop QR axles coming out, not all of the road forks I've seen have these.
I think the fact that the dropouts are angled slightly forward is a better preventative measure. Through axles are even better still, but these seem to be limited to downhill bikes or heavy duty MTBs.

Re the Hydro STI's - apart from the Velotraum Magura converter, they are a bit naff IMO. Messy and not really a 'solution', but something that works. Unless there is a mjor difference between hydro & cable, it'd be more of a PITA than a solution to me. Having separate levers is not a solution either.
So far (even with an Emergency stop heading into Norton Summit on the weekend) I'm more than happy with the disc so far.

Probably the only advantage I'd see is if you are doing lots of descents, that a bigger disc would give better heat disipation, but that'd be about it.

The lawyer lips in the article they were referring to probably looked like this, which take considerably less force or looseness for failure then the big ones on a MTB fork.rkelsen wrote:Yes, but according to one of the links you posted, lawyer lips don't necessarily do much if the force is great enough.cobba wrote:MTB forks have 'Lawer Tabs' as a backup to stop QR axles coming out, not all of the road forks I've seen have these.
I agree that forward facing dropouts are a good idea, through axles are a stronger way of holding a wheel on and with what you said about caliper placement on the fork, but I'd still rather have big lawyer lips on a fork then to not have them.rkelsen wrote:I think the fact that the dropouts are angled slightly forward is a better preventative measure.

Was thinking a bit more when building up the rear wheel (Velocity A23 rim and DA7700 hub) that whether the issue is the same for a road bike, primarily due to the positioning realtionship of the caliper & dropouts, as well as the angle of the dropouts.
Thoughts anyone ?

$400 for a single brake, extra weight, awful disc noise and inevitable freezing and alignment issues seems like a poor strategy imo when a whole better group only costs about twice what you paid for a single brake. And blah blah flame me, but having gone through several iterations of builds on the same bikes I should know poor strategy when I see it. /discuss & flame away

Interesting points that you raise, and quite valid for your case. Haven't used SRAM at all.
In MY case, my issue was more that regardless of pads in either 105 or DA calipers (5600 & 7800 series) in wet weather, the 1st brake application often meant that for what seemed like 100m at the time, the brakes did SFA (much like when you see a race car go off the track and get onto wet grass - seems to speed up).
Yep, I used Kool Stop Salmon pads (yes, some improvement), but as the routes I often ride at night during the week hasd many side roads with ignorant drivers, the braking was often a matter of "OH F^^K"
I felt that the disc may be an option, and so far, am very happy with it.
Yes it weighs more, but at the same time seemingly solved my issue above, and also gave me the ability to experiment and fiddle, and also had some other side benefits.
Meh, my bike, my value, your bike, your values.
But will one day have to try a SRAM equipped bike just to see what it is like.
