- Yikes! It’s being built, no turning back now…
Thanks Brant, that feels like a reasonable validation 👍
It’s not really that much LLSer than the existing frame, the problem has been that with a 120mm fork the HA rides superbly, but the seat angle gets pushed back to about 70 or less, which makes seated pedalling, especially on steep ups, ‘interesting’ 🤪
So kinda tried to make it all work a bit better.
Bluto is now compeletely dead, mastodon 120mm pro ext ready to go, but with a a-c 20mm even longer then the outgoing bluto, it definitely won’t go on the ICT without some rather detrimental characteristics.Posted 2 months ago
Looks good, that’ll be great fun.
I did something similar last year. Mines almost identical geo, apart from the HTA which I kept pretty steep at 69 (probably more like 68 with an unsagged 120 Bluto.)
I experimented with slacker by plugging the fat front onto a couple of other frames, but didn’t like the way it felt.
Here’s mine – I absolutely love this bike!
500 reach (I’m 5″10)
60 BB drop
PF46 BB 120 wide
All put together with the phattest tubing available.Posted 2 months agojoebristolSubscriber
Ah not quite tempting enough to have a go myself then! Wife would go mental.
Love my Vitus Sentier – if it had been a bit cheaper it could have been tempting to get a Ti version of largely the same geometry made up – perhaps with a tiny bit longer reach / wheel base / front centre, but not by much. Just enough to try and keep the front wheel down a little easier on steep climbs.Posted 2 months ago
If anyone is interested in going down this path, I highly recommend this site:
I know Andrew is on here, but I can’t remember his log in.
I started this 2 years ago, but we got a bunch of stuff knicked whilst on holiday so money went elsewhere for a while. Was great to reinvigorate it, and Porter at XACD is great to deal with, if somewhat aggressive!Posted 2 months ago
Sorry scotroutes! next time I’m up in happymore you can have a go, and either marvel at the design, or laugh hilariously at all the things I got wrong (I can already spot one niggle).
Roverpig – no, I’m going to leave it totally raw (unfortunately that look has kind of been given rather negative associations now by Sick!, cest la vie)Posted 3 weeks ago
Hurrah, Hurrah! The build is finished! Rejoice! And now ridden both for a shakedown and then properly in anger this morning.
The fit and finish of the frame was extremely good. Everything faced and chased properly, everything fitted as it should, really excellent and allayed the biggest fear I had with this custom route, of being delivered a lemon.
Majority of components were basically swapped over from my ICT, with the exception of the forks.
It rides superbly – steep, Techy, climbing now a much simpler affair with a steep seat angle, long reach does indeed give a great feeling of moving about the bike, the head angle combined with reach is wonderful on both the fast and the techy downs.
It is also considerably stiffer than the ICT. Only now do I realise how much that frame flexed – whilst on every ride I appreciated the ‘give’ when landing a jump, I had kinda forgotten about how many times I would stop and check my frame for a crack in the chain stay or something, as there was so much lateral flex.
Not any more! ‘NANNY’ Gives a huge amount more confidence on the way down, and there is definitely a feeling of that titanium zing (I’m telling myself that anyway… 😂)
Have to mention how utterly spectacular the Mastodon pro EXT forks are compared to my knackered old Blutos – they track where you want them to, actually absorb bumps and not just hard landings (that was pretty much all the Blutos would do for the last 18mths or so, regardless of how much servicing they got), and they also fit 26×4.8 and 29×3 tires properly, with decent clearance rather than the 1-2mm previously.
Was quite an eventful first couple of days, buzzard attack and me snapping the rear maxle to name but two, but my goodness I am a happy camper.

That is a superb looking bike. the proportions are excellent, you would not believe it’s a 29+. it’s only when you look at how small the chainring looks do you realise the size of it. Well done and that price is amazing. I paid more than that for my heckler frame 22 years ago (sh1t that makes me feel old).Posted 4 days ago
cheers Tim, lets hope it was good value, and that it doesn’t suddenly fold and die anytime soon!
RP – hard to say, I suppose a lot could have been down to the forks, but I think that feeling of ‘I’ve got a rear puncture’ or ‘the frame must have snapped’ must
come from around the frame? I remember my old Roadrat feeling the same way if the rack was loaded up.
The scenario I was most aware of the bluto’s shortcomings, other than not working as suspension forks, was on steep, techy, twisty downhills, either slow or fast. That TWANG feeling as the forks finally decided to point the wheel where the handlebars were telling it to, or the horrible wiggle as it decided to take its own route through a rock garden. not fun!
I used to think the frame flex feeling was down to tire pressures being too low, but thats clearly not the case as they re the same on the new frame. For sure, the forks make a dramatic difference too.Posted 4 days ago
Yes, fair point, that flat rear feeling must be the frame I guess. There is a fair bit of mass in those wheels and the rear of the ICT is pretty skinny, so it makes sense. I know what you mean about the Bluto. I sold mine and went back to a rigid fork fairly quickly as I couldn’t get used to that “magical mystery ride” feeling. It would be fun to try a decent fork on the fatty sometime though. Maybe a Mastadon on my Dude at some point. I think the SA is steep enough that it could cope with a 100mm EXT version. Too many other “projects” on the go at the moment, but looking forward to hearing how you get on with yours.Posted 4 days ago
Cheers all for the nice comments, I love it.
(1).Ti custom fatbike frame with raw finish(remain welding color)
FOB XI’AN USD695.00/set 1set USD695.00
Extra costs of 142×12 thru axle dropout:USD115.00
Extra costs of CNC logo in the head tube:USD95.00
Shipping costs(EMS express):USD165.00
Total: 1128 usd, which is about £862
It is quite ridiculous value, assuming it doesn’t fold in half, snap or shear of course.
That price also includes about 40 iterations of the CAD drawing, and lots of communication. There are so many things to consider, I got most right, but some things were missed by me (e.g. stealth dropper exit hole is center of seat tube, should have had it further round to NDS for better routing). Helped that I started from the Surly geometry, but on close inspection the numbers manufacturers quote were not very accurate at all. Get handy with a measuring tape!
Remember – this is totally custom, with all the benefits and risks that entails. If you tell them to make it with a 105mm PF bb that nothing will fit, or spec a 76degree head angle and 65 seat, they will probably build it. Also, if you start to go more esoteric, bent seat tubes, tapered head tube etc, costs go up. Mine was relatively simple.
It’s not something to be done in a rush!
Spanner.org.uk is a brilliant place to start, and I can highly recommend XACD – process, and quality of final product, was excellent.Posted 4 days agotpbikerMember
My first thought (other than that looks ace) was how small the chainring looks! Makes sense if they are 29er wheels..that bike looks perfectly in proportion..but more like a 26er than a 29er. It must be huge!
Second thought..850 quid for a custom ti bike?? That looks like the deal of the century to me. Whats the catch? Do you need to have the design skills to send them the plans, or can you just pick a bike you like, copy all the measurements, tweak it a bit, and then send them over the geometry?Posted 3 days ago

Thats basically it. Can’t speak for other builders (e.g. Walty), but Porter at XACD, whilst being rather aggressive and direct, in hindsight is extremely helpful and patient – he just wants you to commit cash and not fanny about wasting their time. Fair enough!
Be aware that you have to spec everything – tube diameters, wall thickness, dropouts, cable stops, that we extra stay between chain and seat stay on the NDS, gussets, butting, bottle bosses… Everything.
So thats a risk, as is the somewhat uncertain warranty situation.
Though they are also pretty helpful – e.g. I made sure they new I was a big fella, and didn’t want a wet noodle of a frame, so they specced up the tubing diameters and thickness in a couple of areas.
I didn’t go down this route as I wanted bling Ti, I just wanted a bike frame that addressed my desires. I was in no rush, except for the current HT frame gradually dying. The whole process I really enjoyed (except choosing the bb shell width and diameter (e.g. PF or BSA, 100mm or 120mm etc) as if I got that wrong the whole thing would be buggered)
In the future I may use a nice steel builder like Ben Cooper, but this gives a chance to play a bit without investing too much cash.
Also already thinking about a 29+ full suspension…Posted 3 days ago
I’ll stop posting about this bike, I promise, but 3 things that have to be mentioned after a proper proper thrash this morning
1) in general – wow! Fabulous! Superb! 😃
2) LLS geometry (and I know mine is not that extreme) – by jings, theres no lie, it really works, utterly fabulous through some hideous, sketchy, sloppy, steep rocks and mud this morning. Tons more confidence, and, EEK, speed! The horrible ups were much more simple to climb
3) Titanium – sorry, I know it sounds like bullshit, but it really does have something special. Wow.
hurrah!Posted 2 days ago
