A 52mm fork with the 70.5HTA of your frame will give you 72mm of trail if you are using a 43mm tire.
If you combine the fork's 52mm offset with a +1 degree setup of the Wolftooth headset, you will have 65mm of trail if you are using a 43mm tire.

65mm of trail is, to me, quite reasonable. My bike has 61mm of trail right now(72.5HTA, 50mm rake, 44mm tire) and 65mm of trail would be fine in the end too.


A 70.5mm HTA for a gravel bike just seems bonkers. It will appeal to some, clearly, but man it sure seems pretty extreme when paired with one of Lynskey's stock forks. You get 79mm of trail if you are using a 43mm tire. Thats wild. I guess if someone is using it primarily to underbike on MTB singletrack, that amount of trail may be appreciated? But it sure seems like a crazy amount of trail geometry for gravel roads(and paved roads to connect gravel roads).
That sounds like a very flexible setup. Thanks for pointing it out! Where did you see that price? I'm seeing more in the $600+ range.

This Tekne series (https://www.teknecycling.com/collect...art-2-geometry) is very enlightening; moving from theory to real world experience!

This dude ^ knows what he's talking about ^.

The Wolftooth headset won't work with a headtube longer than 140mm. HT length on a medium GR300 is like 145mm. I'm guessing that the head tube height restriction is because the greater the distance between the bearings means that with the +1 or +2 angle change, there won't be room for the bearings because of the new steerer tube angle. That's merely a guess, I don't know it for a fact.

I also noticed that Lynskey is now selling a GR400 and doubled down on the 70.5 HTA and 45mm fork offset. Yow.

So, what is the purpose of the aluminum inserts in the seat tube and headset? Just a cheap way to achieve the needed inside diameter? Is a squeaking seat post a common occurrence (that would drive me further out of my mind)?

To think there is only 1 good trail number would mean lynskey, and others, designed a terrible gravel frame.

Reality is that there are lots of geometry options because there are lots of people who like different geometry.
I agree with this. I was going to recommend to the OP to just buy a fork from Lynskey and was really surprised at the poster who hated the 45mm rake. I have the standard fork on my GR300 and think it handles perfectly, and it's a nice looking fork with a decent weigt.

But I'm not denying that some riders can perceive and make a personal assessment of this stuff. Not me- it's just satisfactory for my riding.

I ordered the Columbus Futura Cross fork and it should be here tomorrow. I like the adjustability of it.

I appreciate everyone’s advice. While I understand geometry and handling, my experience is limited to road bicycles and off road motorcycles and cars, so a gravel bike is new to me.

Most folks use the same pedals and shoes as they do for a MTB. For me, it's Crankbrothers Eggbeaters. Shimano SPDs are also a popular choice.

Eggbeaters are known for their ability to keep functioning, even when things are packed with mud. I did a gravel race last year where a number of folks with Shimano pedals were having to stop to scrape mud out of the soles of their shoes just to be able to clip into their pedals. I did not have the same issues with my Eggbeaters. That said, Shimano XT SPDs are well regarded for their long-term durability, where Eggbeaters sometimes need to be rebuilt. I'm not convinced Eggbeaters are the best pedals, but they're what I'm currently using. They can sometimes get a little a little noisy/creaky, which can be annoying. Time ATAC pedals are also a good choice.

As someone who owns a Lynskey Helix GR and does some commuting on it and some credit card touring, I appreciated the trail conversation and opinions. No issues/challenges with my setup but it was insightful should I opt to expand my luggage solutions or go deeper into the woods.

I've never given much thought to rake and trail on a bicycle, so I'm really curious to build it up and see how it handles. Forks are supposed to arrive today and frame in early July.

I've found that a steering damper works great on my Honda mountain bike. Are there such things for bicycles? Seems like it could be a great solution for low speed handling issues.

The concept has been attempted, but nothing has proven to be successful. Personally, I don't want anything slowing down my steering, especially during low speed situations.

Honda makes bicycles??

They do! They are kinda heavy, have weird pedals, but are very fast

Seriously, the dampers are speed dependent, so turning the bars slowly or even moderately quickly doesn’t slow things down. I think they have some sort of special oil that increases in viscosity the faster the internals move. They are highly effective with no drawbacks if properly adjusted. They only weigh a couple pounds, but that’s prohibitive on a bicycle.

Just snagged a Fulcrum WIND 42 Front Wheel and I have a Rene Herse 700C X 44 Manastash Ridge TC Tire - Extralight (tan) on its way.

That leaves handlebars, stem and seatpost (and the inevitable little bits). Recommendations?

Rear brake mounts are for 140mm discs. Lynskey does not state that, I did not know and am waiting for an adapter for mine. Should be here Monday.

The rear disc mount looks like a flat mount, which Iím not really familiar with. Which adapter is needed?

Flat mount is typical for gravel bikes. Most folks run 140 rear/160 front.

I received the same GR300 frame early last week. The things you learn as you build. This is the first time with a disc brake install for me, and have had to order parts as I discover something I didnít know before. I am installing a Shimano group with 160mm flat mount discs front and rear.

The adapter is Shimano SM-MA-R160D/D.

Also, the mount is 15mm thick. The length of the mounting bolts is specific to that thickness.

Yeah, and other than bike specifics, I’m also learning that if I need or want to use a mill or lathe to make something work, I’m probably doing it wrong……

The Shimano hydraulic disc brakes are great. I have them on three bikes. Will put the dual piston versions on our tandem in a few weeks.

What are you using for a drivetrain?
