Finding the right size bicycle is crucial for comfort, performance, and safety. Unfortunately, Trek didn't publish readily available, comprehensive size charts online for their older models like the 1994 Trek 850. This makes determining the correct size a bit more challenging. However, we can leverage available information and common sizing practices to help you find the right fit.
This guide will help you understand how to approach determining the correct size for a 1994 Trek 850, even without a specific, published chart. We'll explore common methods and address frequently asked questions.
How to Determine Your Trek 850 (1994) Size
Since a precise 1994 Trek 850 size chart isn't readily accessible, we'll need to rely on indirect methods. The most reliable way is to measure your inseam and compare it to general mountain bike sizing guidelines.
1. Measure Your Inseam:
- Stand against a wall with your shoes on (the shoes you'd wear while riding).
- Have someone measure from the floor to your crotch. This is your inseam.
2. Consult General Mountain Bike Sizing:
While not specific to the Trek 850, general mountain bike sizing provides a helpful reference. Keep in mind that sizing can vary slightly between brands and even within a brand's model years. However, these are approximate guidelines:
- Small (15-16.5 inches inseam): Generally suitable for riders under 5'4" (162 cm).
- Medium (17-18.5 inches inseam): Suitable for riders between 5'4" and 5'8" (162-172 cm).
- Large (19-20.5 inches inseam): Suitable for riders between 5'8" and 6'0" (172-182 cm).
- Extra Large (21+ inches inseam): Suitable for riders over 6'0" (182 cm).
3. Examine the Bike Itself (If Possible):
If you have the opportunity to see the bike in person, several other clues may help determine its size. Look for:
- Top Tube Length: Measure the length of the top tube (the horizontal tube connecting the head tube to the seat tube). Longer top tubes generally indicate larger frame sizes.
- Seat Tube Length: Measure the length of the seat tube (the vertical tube from the bottom bracket to the top of the seat tube). This measurement is also correlated with frame size.
- Standover Height: Measure the height from the ground to the top of the top tube when the bike is standing upright. You should have about 1-2 inches of clearance between your crotch and the top tube.
These measurements, along with your inseam, will offer the most complete picture of the bike's size. Remember to consult with a local bike shop if you have any doubts. They may have experience with vintage Treks and can offer valuable insight.
