Does anyone know the difference between these two trying stands? Let's plan like the TS-4 is discontinued but still available at many retailers.

On the park tools website, it just says the 4.2 is new and improved or something to that effect. No real details.

I believe its all in the description starting with the word 'updated'

I did read that before I posted but it's a bit vague other than built in thru-axle adapter.

I'd say -0.2

Wow, that looks truly monstrous!!!

I'm seeing notes on the web indicating that the TS-4.2 has a welded base, while the TS-4 does not.

Otherwise it sounds like a bunch of minor updates.

I think the TS-2.2 is designed to accommodate most 29er wheels with tires mounted. The TS-2 would require the 29er tires to be removed.

The TS-4 series appears to be more oriented towards fat wheels/tires, but of course, would be multi-purpose.

Why don't you just email Park Tools and ask them?

I suppose the question is what your need is.

Road Bike Tires
MTB Tires
Fat Bike Tires

Home Use?
Shop Use?

Do you have a TS-4 and thinking of an upgrade, or found a source for a good used one?

Is the savings of a used truing stand worth it to you?

Is the difference in price worth it to you?

Planning to call them today but was feeling a bit impatient while their office was closed (not open on Mondays).

I own a TS-4. Quality stand but was simply curious about the updates in the 4.2 since the 4 was not out that long before the update. Was there a problem with the TS-4? I haven't used it enough to find anything obvious.

Called Park Tools today and here's the answer: The four bolts that attach the caliper arm to the uprights were eliminated in the 4.2 in favour of welding. Apparently the bolts got in the way of very wide tires.

First time calling Park Tools directly and they were a pleasure to deal with. Answered on the second ring and got transferred to a very knowledgeable technical rep. It's such a rarity to get that kind of service these days.
