I'm 5'8" and ride daily for exercise. Use full leg extension to get maximum benefit. Have to keep BOTH seat posts set at their MAX insertion point to get full leg extension 9and in fact don't quite get that on the Step-Over model because the pedals sit higher off the ground). So if you're taller than 5'*' AND insist on using on using full leg extension while riding (like I do) I'd personally opt for a longer seatpost. Other than that, the Zoom DJC suspension seatpost is awesome. And BTW, when you sit down on the seat the shock absorber compresses 1"-2" (mine averages 1.5" compression). Need to take that into account when purchasing a suspension post. **Q: Does anyone know how this compares to the suspension seatpost included in the Lectric Comfort Pack?** A: I purchased this to use on my Radcity power bike. I like it, as far as it compares to Lectric suspension post the DJC bike post has a 30 Lbs. higher rating and it has a 1/4 inch more travel. It also comes with different size sleeves to fit a variety of bike mounting holes. And most important it is about 50 dollars cheaper when purchased separately. **Q: I just installed the post on my bike, made few clockwise turns (tighten) but seat just sunk, cant feel rebound. I weigh 150 lbs. Suggestion please** A: hi friend, the first days it is a little hard. but after you ride with it 1-2 weeks, the spring will softer. try to ride it more times. you will feel better. **Q: My seat post says 31.8 will the 31.6 work? Does it come with a .2mm shim?** A: My seat post arrived with just the post. No shims were in the package. ## Frequently Bought Together - DJC Bike Suspension Seatpost Shock Absorber Damper Post 27.2 30.9 31.6 mm, Lightweight Aluminum Body - Comfortable Seat Cushion for Men Women with Dual Shock Absorbing Ball Memory Foam Waterproof Wide Bicycle Saddle Fit for Road Bikes - ROCKBROS Bike Seat Comfort Bike Saddle Mountain Bicycle Accessories for Men Women Soft Wide Bike Seat Cushion Dual Shock Absorbing with Reflective Strip --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/358575317-djc-aluminium-parts-bicycle-suspension-seat-post-shock-absorber-27](https://www.desertcart.jp/products/358575317-djc-aluminium-parts-bicycle-suspension-seat-post-shock-absorber-27) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-05*
