Springs were not adaptable to my TS-2, the ends were not long enough to stay in the keeper holes on the stand, also they were half a turn shorter then the old springs which I used.The instructions are excellent, kudos to whom ever wrote them.

I was looking at buying a new stand so that I could true up my mountain bike tires, then I came across this set and just about jumped out of my chair saying YES, now I am able to true any wheel I have with no problems!!!! And you can not beat the price, there was nothing wrong with my stand other than not being able to true my 29er tires, now I do not have any problems, none at all. Thanks much, Randy

I love the plastic protectors. They prevent any scratching of my recently paint 1952 Schwinn S-2 rims.
Worked well to upgrade my TS-2 so that I can work on wheels with bigger tires in place. Im now able to true my 29er wheels more quickly. Thank you!
What's not to like? One of the most significant and necessary upgrades you can give your ts-2.
Love this add on!!! Wish I knew about it sooner! It now accommodates larger tires and has plastic guides. Thanks again!!!
During transportation of the stand, caps and one of the calipers were damaged. Replaced everything very quickly, parts of excellent quality. Park Tool in my opinion is one of the best manufacturers of tools.
My old Turing stand working fine building my 29" wheels but I had a problem when I put a tire on it and needed to tighten the spokes more. This solved my problem and fit perfect.
If you have an old TS-2 truing stand, this is pretty much a must-have upgrade if you want to be able to true fat bike wheels or MTB wheels with the tires on. It installs quickly and easily, and adds new versatility to a great old tool.
