Further on the clock fettling has occurred and I've now got the front feeling really good, much firmer lever feel. Just need to get the rear the same, although I think that's more down to the tape on the pads (only bothered doing the rear for now).
@craigjames - Don't bother with the supplied titanium olives etc, I've had 2 leak now. The shrouds etc work as they should but overall his stuff isn't spot on.

This looks seriously smart with the silver rims + levers, love the look of those bar/stem combos as well

Haha, fair enough. They'll probably firm up a little once you've used them. Disc brakes are super sensitive to caliper alignment, and if they're even a tiny bit off (which realistically they're always going to be unless you have everything perfectly faced and it's all been made perfectly) you get a decrease in lever feel. Once the pads have bedded in to the rotor that should be lessened because basically it'll have adjusted itself (through the pad braking material) to be as square as possible with the rotor.
That's quite often why 4-piston setups feel a bit mushy too. I developed a slightly sticking piston on my MT5s which meant that they weren't all operating evenly, and it made me think the brake had leaked because the lever feel went so squishy and it lost so much power. It's less noticeable with MT7-style individual pads, but for the MT5/Hope style pads that cover both pistons on each side it's more noticeable. My E4 pistons used to get sticky all the time so that might have been having an impact on that too, possibly.
Further good points! I've also just discovered a slight leak on the front so that'd certainly a main culprit.. Doh!

I reckon with the pretty massive leverage they've got (T4 Trial Zone is close to the Trickstuff Maxima), you're better off with stainless steel braided hoses. Trickstuff supplies the Maxima exclusively with those hoses, to prevent the bite point becoming too squishy.
I've got some T4 V4's on order, with the braided hoses. Long wait though, hope to give my impressions within a month or so.
You could be right, I've never found braided to be a performance upgrade but in this instance it could be part of the issue.
26 minutes ago, Mark W said:Some of the squish may be in part down to the design of the Trial Zone caliper - from memory, they can splay open a touch when you brake (similar to a 4-bolt frame with no booster) as there's not a huge amount of material in the caliper itself. If the lever's generating more power now it might be exacerbating that aspect of them a bit, and there'll most likely be a bit more flex within the blade itself compared to the old levers.
That's interesting to hear about the pads sitting closer to the rotors now. When you've been trying to bleed them, have the pistons been fully retracted into the calipers?
That also makes sense regarding the TZ calipers, I can't visually see it happening from above but doesn't mean it's not. However I had E4s before and found my mates TZs to have a much more solid lever feel hence the switch.
Yeah I always make sure the pistons are fully returned, I can't comment too much here though as I'm coming from different calipers so could just be that (combined with different pads also).
All of this is before I've even ridden them.. So take my thoughts very lightly haha.

They definitely are a bit different to the previous levers, but i do prefer the feel. Mine have a good positive bite point and then a bit of squish after. Guess it's the longer lever combined with the slightly smaller piston diameter. I've tried bleeding them multiple times and no change, so they are as they are i guess! Unless there's a trick to bleeding them i don't know about... Do you also find that the pads sit very very close to the disc? Might also be a side effect of the smaller master cylinder piston size.
Thanks for the info on the Ti bits, strangely enough that's where i had been looking; good to know about the bleed nipples though... shame as I do love the Ti bits, my OCD may give me a migraine if i have to leave them as steel lol!
I'd say the same on the bite point + squish, I'm yet to ride them so can't really comment too much.. But initial impressions aren't great there. I did give them another bleed yesterday also but not a single bit of air so as you say, it's how they are.
I've found the same with the pads, even with brand new rotors I've still got a tiny bit of contact on the front. I've added some tape to the rear pads and it's really bad, but should settle down after the tape's bedded down.
I'm with you on the Ti, he also didn't send me the banjo bolts with this order. He can be quite difficult so I'm not bothering asking for the £20 or whatever back this time round.

They look lovely! Where did you get your Ti fitting kit from? Ti bits and some Jitsie/Trialtech pads are next on my list for upgrades
They really are a step up from the previous generations in terms of feel. Do yours have a bit of lever squish?
Thanks Craig. I really disliked the new levers when they were launched but they've grown on me for sure. I order from titanium planet, I'd advise to not bother ordering the titanium bleed nipples though as I've had 2 sets now and neither seal - https://titaniumplanet.com/en/
Ah so it's not just me with the squish then! I was planning to give them another bleed today before riding. The longer blades can't be helping with that.

Stoked to try these out.
I really wanted a silver set and I’m too impatient to wait the lead time (was advised 10 weeks then they added another 10).
Bought a set of tech 4 E4s and got a pair of trial zone calipers, some titanium bling and jitsie pads. Bit of an arse of a job I must say! Lever feel is really nice, I like the lower profile of the reservoir too.

I’ve had no issues with mine. Is your chain line decent?

Impressive! … what stem is that?
Cheers dude. It’s the longest bbb one, 110 from memory!

So this bike has evolved somewhat. Had a fantastic week in Barcelona, dream bike for the job. Covered 20 miles+ a day.

Tarty have stock now. Lever feel is lovely and light. The whole thing looks smaller in person than on photos, weirdly. Power is going to be a touch more than the Tech 3, with associated reduction in pad / rotor clearance.
I’d ordered a silver set through a friend’s trade account, but I guess black products are always going to be at the front of the production line!

So, anyone got some time on the T4 TZ yet?
Mine just got pushed back another 10 weeks so have pulled the plug
-
Unfortunately mine did this again after a few more rides. Have switched over to external now.
-
So I got to the bottom of my creaking hub, simply needed to add some grease to the seat of each pawl (thanks @Daan).
The dumonde hub oil wasn't cutting it.
-
i9 help please:
My rear Hydra is creaking under light load. Any ideas what to check?
Im running a tiny amount of freehub oil, double springs. 135 x 12mm bolt through. Everything looks ok in there to me. I’ve just swapped the axle from a 135 x 10mm bolt in but had the same creaking on both set ups.
any ideas chaps? Also if any of you have upgraded the bearings do you know what to go for?

I have a set, though not on the trials bike. Impressed with the quality, weight and feel.
Note the 3 bashing / spider bolts are 180 degrees rotated from "normal", so an Inspired bash might need some fettling.
I noticed yours, that bike is something else.
I actually ordered a set after a few beers and have since been wondering if this is my most daft purchase to date. I also only just noticed today that Danny’s bash is on in reverse, I’m hoping no modification is required!

as far as I know Danny hasn't broken his set yet if that makes you feel any better
Does indeed Ali, thank you.
-
Ludicrous price aside.. Has anyone taken the plunge? 10 year warranty is appealing, although not sure that would cover trials use.
I’ve seen Danny is running them, however as a sponsored rider he could be on his 10th set for all we know.
My main concern is that they are hollow, the official test video shows they dent from a serious rock strike however still hold some impressive strength. I rarely catch a wall but it’s certainly a worry.
-
Ok I’ve decided I fancy a set of these. Anyone know where or when they will be in stock?
After a silver set

That’s alright the frame sold for more than that
More than £8000?

That has to be up there as one of the best looking trials bikes. Love the spec too!

Thank you both.
Adam - I’ll try source the axle + end caps first but will reach out if no luck.
Edit - All sorted. New axle + end caps on the way for both rear hubs. Cheers guys

Just the olives / inserts as you say. I've had the same issue twice with these ti ones, although prior to that I fit some on my MT7s with no issues.
Certainly not worth the hassle, the only annoyance is that you buy a full package through his site so you can't not 'purchase' them so to speak... But certainly don't bother fitting them. Forgot to mention I also bought some lever pivot bolts for my tech 3s that wouldn't fit. All in all, not great haha! Good to know they'd not pass the tarts QC.
Let's be honest, ti really is a waste of money. I'm not even sure the top elite riders bother? But who doesn't enjoy bike fettling and pimpin'?
Worst thing I ever did was move my bikes into my office
