Lapierre Zesty AM 827 Wheel Standards: The Original Hub and Axle Listing
Lapierre Zesty AM 827 Wheel Standards can look like one long string in an old specification: wheel size, hub dimensions, freehub and axle name appear together. They answer different questions. Separating them is the useful first step when identifying an existing wheel or preparing an enquiry about a replacement.

Decode Lapierre Zesty AM 827 Wheel Standards
The AM 827 entries on PDF pages 36 and 100 of the 2015 catalogue name SRAM Roam 40 UST 27.5-inch wheels. The listing continues with 15 × 100 front and 12 × 142 rear, XDriver and an LAQR-12-E through axle. Keep the full original description rather than reducing it to “a 27.5 wheel.”
| Field to record | Original catalogue entry |
|---|---|
| Wheel family and diameter | SRAM Roam 40 UST, 27.5-inch |
| Front hub dimensions | 15 × 100 mm |
| Rear hub dimensions | 12 × 142 mm |
| Freehub wording | XDriver |
| Axle designation | LAQR-12-E |
These are identification fields, not a complete replacement order. In particular, a hub-spacing figure is not the complete length or thread specification of the removable axle. This source does not provide the missing thread-pitch information needed to identify an arbitrary replacement axle.
Distinguish the tyre label from the whole wheel
The same model entry specifies Schwalbe Nobby Nic Tubeless Easy 27.5 × 2.35 Snake Skin tyres. That records the factory tyre, not maximum frame clearance or a guarantee that a different tyre with a similar label will fit. It also cannot tell you whether today's wheel retains the original rim, tape, valve or tyre.
Photograph the current rim decals, hub markings, cassette interface and tyre sidewalls. Ask the owner about replacements. If the wheel has changed, record the fitted part beside the catalogue entry rather than quietly treating the original specification as an inspection result.
Prepare a precise parts enquiry
Give a mechanic or supplier the model edition, front or rear position, actual hub identity and the relevant markings. Ask them to verify the complete assembly and required interface before ordering. Shared diameter or Roam branding alone does not prove that a wheel from another bicycle will fit.
This guide does not approve Boost adapters, wheel-size conversions or a freehub swap. For the separate original gearing question, read the AM 827 drivetrain guide. The Lapierre reference hub connects these model-specific records.
FAQ: Reading the original wheel entry
Does 12 × 142 identify every axle detail?
No. The hub dimensions do not supply all axle dimensions or thread details; verify the actual frame and axle specification.
Does the original tyre prove maximum clearance?
No. A fitted factory tyre is not a stated clearance limit, so do not infer a larger-tyre recommendation from it.
Can the catalogue identify today's fitted wheel?
Only as a baseline. Lapierre Zesty AM 827 Wheel Standards must be compared with the actual parts and any documented changes.
