Inventory management for Shopify cycling apparel brands

The inventory problems cycling apparel brands run into

• Size and fit variants. A single jersey style can run six to eight sizes, often in men's and women's fits, and sales rarely split evenly across them. L and XL usually sell faster than XS and S, so reorder quantities need to reflect the actual curve, not a flat split.
• Seasonal technical fabric. Thermal bib tights, winter jackets, and arm warmers only move for part of the year. Carrying a full size run of winter gear into spring ties up cash that should go toward summer kit.
• Colorway and print proliferation. Many brands release limited colorways or team kits each season. Each colorway adds a full set of size variants, which multiplies SKU count fast and makes manual reorder tracking error-prone.
• Overseas manufacturing lead times. Technical apparel (jerseys, bibs, shells) is often made overseas with long production runs and minimum order quantities per colorway and size. Late reorders can mean missing an entire season.
• Pre-order and small-batch drops. Some brands run limited drops or pre-sell kits before production. This makes forecasting trickier because demand signals come in before stock exists, and those orders don't behave like normal reorder patterns.

Seasonality and demand

Cycling apparel has two clear peaks: spring into early summer for jerseys, shorts, and lightweight gear, and autumn into winter for thermal layers, jackets, and cold-weather accessories. Many brands also see a smaller bump around big sportive events or race weekends they sponsor or supply. Because manufacturing lead times for technical apparel are often long, orders for a season's kit usually need to be placed well before that season starts, sometimes while the prior season is still selling. Plan size curves and colorways based on last year's sell-through by size, not just total units, so you don't overbuy slow sizes and underbuy fast ones.

Suppliers, lead times and minimums

Most cycling apparel brands work with overseas technical apparel manufacturers for sublimated jerseys, bibs, and jackets, and these suppliers often require minimum order quantities per size and per colorway, not just per style. Smaller accessory items like gloves, socks, and caps may come from separate suppliers with lower minimums and shorter production times. Domestic or regional cut-and-sew shops are sometimes used for small-batch or sample runs, usually at higher cost but faster turnaround. Lead times vary widely by supplier and production schedule, so overseas apparel runs often take several weeks to a few months, while accessory reorders can be quicker.

Worked example

Say your best-selling men's jersey in size L sells 2 units a day on average. Your overseas supplier has a lead time of 45 days, and you keep 10 days of safety stock for that size. Your reorder point is 2 x (45 + 10) = 110 units. If you want 60 days of cover after the order arrives, and you currently have 80 units on hand with 0 on order, your order quantity is 2 x (45 + 60) - (80 + 0) = 210 - 80 = 130 units. The supplier's case pack for that size and colorway is 20 units, so you'd round up to 140 units to stay on a clean case count.

Try it with your own numbers in the reorder point calculator, or size your buffer with the safety stock calculator.

A simple system to start this week

1. List every active style, colorway, and size as its own SKU with accurate on-hand counts in Shopify.
2. Pull last year's sell-through by size for each style to spot which sizes consistently sell faster.
3. Confirm each supplier's lead time and case pack or minimum order quantity per size and colorway.
4. Set safety days higher for your single overseas manufacturer and lower for faster domestic or accessory suppliers.
5. Review the weekly reorder email before a season's production window closes, not after.
6. Separate pre-order or drop-based styles from standard reorder stock so forecasts aren't skewed by one-off demand.

How SteadyShelf fits cycling apparel brands

SteadyShelf tracks forecasts and reorder timing per size and colorway, so you get an order-by date for each SKU based on your supplier's lead time, with quantities rounded to that supplier's case packs and minimums. It will draft and send the purchase order once you approve it, and receive stock as it arrives, including partial shipments. It doesn't handle pre-order demand planning, manufacturing or BOM tracking, or transfers between warehouses or retail locations, so for drop-based releases and multi-location stock balancing you'll still need to plan those manually.

$29/month flat, unlimited products and suppliers, 30-day free trial.

SteadyShelf is launching on the Shopify App Store. Join early access to get the install link first.
