I have a giant rincon from the 90's and I want to put suspension forks on them and keep the 26" tire what size forks should I be looking into getting

    Welcome to the website! A picture of the front of your bike should help identifying what parameters your current fork has, and what replacements (if any) are out there compatible with your frame. Nov 14, 2019 at 14:15

If the bicycle has a rigid fork now and this fork is not marked as having "suspension-corrected" dimensions, in particular, axle-to-crown length, then this bicycle is not officially compatible with any suspension forks. Simply put, installing such a fork will either raise or lower the front of the bike, which will affect its steering properties and ground clearance among other things. There may be other problems, like the new fork's crown touching the downtube when turned.

If the current fork is "suspension-corrected", then it should be possible to replace it with a suspension one. Bikes of the era rarely had suspension travel more than 100 mm. There are other compatibility parameters to consider though, like steering tube diameter and shape, wheel axle type, brake system etc.

A bigger issue is, however, that 26"-wheels and accompanying components are (unjustly IMHO) considered obsolete by the market. It is hard to get new good parts for them, as most of new MTBs are sold with either 27.5" or 29" wheels. Those few cheapest new bikes with 26"-wheels out there are coming with OEM forks (i.e. those cannot be bought separately), and those forks are not especially known for their stellar damping properties.

The dirt jump bikes are however fixed to the 26" wheel size. It should be possible to get an aftermarket fork with 80-100mm travel for them. However, as I mentioned before, they tend to have modern "standards" elsewhere, such as through axles, tapered steering tubes and disc brakes, things not known in 1990's.

    I just checked the first eshop and there are many 26" forks available. Some with V-brakes or dual. They do come from OEM manufacturers and are just branded by some cheap brand (SR Suntour and Force in this eshop) but that may be more than adequate for that kind of bike. Nov 14, 2019 at 14:37
  • @VladimirF yeah. However, it is often easier to get decent damping from a rigid steel fork than from a "suspended" cheap SR Suntour. I am even not talking about trail-worthy huck-eating suspension, just something capable of smoothing out gravel road chatter. Cheap "suspension" forks are both heavier than their rigid counterparts, they do not do their job well, and they are less reliable than a plain rigid fork, while costing as much.

  • I don’t do MTBs but I will side with Grigoriy on this. A rigid steel fork plus a decent tire provides enough suspension for the average rider who isn’t using the bike in a performance setting.

You need to match the axle-crown height (on the loaded suspension), the Steerer (if early 1990's will likely be impossible to find quill stem, otherwise straight 1 1/8") Modern forks used tapered steerers so be carefull. You will also need to match the axle, which will be 9mm QR not through axle, and the fork wil have to have V Brake bosses unless you want to upgrade to disc brakes (means new hub which practically means a new wheel)

You can get new forks that will fit the requirements, but they are from lowest end range of what is manufactured today by low end manufacturers - cheap and generally pretty nasty. Quality forks from a donor bike upto early 2000's might be a better way to go (after that quality forks wen disc), but age will have taken its toll unless well maintained and not used much. Examples of used forks that fit the bill are getting expensive.

Ultimately, it fits into the fun(*) to do but not economical bracket unless you can find good used parts, which is the real challenge.

  • Fun - something you do that is challenging, time consuming and costly just because you can.
