The new kids HUP xc20 & xc24 MTB bikes!

The little groms version of the HUP xc, the HUP xc20 (20" wheels) & xc24 (24" wheels) are lightweight MTBs for cross-country or techy trails. With lightweight double-butted 7005 frames, progressive geometry and custom components - they are trail-blazing bike for little riders, whatever the terrain! Nothing compares for weight & spec at this price...

  • Progressive Geo: low standover, slack 66º fork, short stays and 100mm or 120mm forks
  • Full Size Wheels: small geo on 20" (406mm) & 24" (507mm) and up to 2.4" tyres
  • Lightweight: double-butted 7005 Aluminium, UDH, bikes from 8.3kg, the lightest available
  • Custom Components: custom length cranks, stems, seat posts, saddles, bars & framesets

Lightweight for the climbs, but still capable of the technical descents, as found on modern trails and bike parks. The low standover/low stack gives riders the space to move on the techy sections and keeps shoulders down on faster sections.

Big wheels, latest progressive geometry (short chainstays, 66 degree fork angle) and correct fitting components create an agile, responsive and seriously fun bike. The grom squad has had a riot testing and developing the HUP xc in the Glentress forest, near Peebles. Fast and flowing, tight and techy, steep and gnarly - it handles pretty much everything!


With 2 frame/wheel sizes covering riders from approx 105cm up to approx 145cm tall, now all the kids (not just Mum & Dad) are in for a treat. When progressing up a frame, they can carry-over many components like groupset, bars, saddle, brakes etc Thanks to the SRAM UDH hangher, parents also benefit from component sharing, life is simple with everyone on the same mech hanger!

A low maintenance design with full length outer cabling (including option to fit a dropper) plus the latest standards like thru-axles, 2.4" tyre clearance and a tapered head tube - ensures compatibility. SRAM's Universal Deraillieur Hanger (UDH) also brings the ease of a widely available hanger.

Choose from Purple, Grey or Silver frames. Every detail has been addressed to make the HUP xc20 and xc24 the most capable kids MTB, without breaking the bank. Don't take our word for it, here are our verified frame weights;

HUP xc20 = 1190g (compared to Nukeproof Cub Scout 20 = 1550g)

HUP xc24 = 1370g (compared to Nukeproof Cub Scout 24 = 1770g)

    …and yes, we have the right size cranks for our riders, so no need to be changing anything! The game just moved-on for little riders...so for all the new XC kit: CLICK HERE
