Cinelli Experience

Finally, there’s a CINELLI Experience that was having issues with its gears. Having assessed the rear derailleur, which had a few battle scars, it was clear the gear hanger had probably taken a knock or two. Out with Park Tool‘s brilliant Derailleur Hanger Alignment Gauge (they have to come up with something snappier than that!) which quickly confirmed the hanger was mis-aligned meaning gear changes were patchy at best. The tool allows you to ‘persuade’ the hanger, which is a relatively malleable alloy, back in to line. Once that was achieved, the derailleur was re-fitted, the gears re-indexed, and fingers crossed, that should be that.

A tale of two Pinnacles

Next up, a couple of Evans Cycles Pinnacles that needed some work. The first, having completed a gruelling 140 miles and a total of 12,000 feet of climbing the previous week, was in need of a gear service. The second, soon to be found cycling between London and Paris for charity had ended up with its gear hanger being bent. Removal of the rear derailleur, attachment of the Park Tool derailleur hanger alignment gauge meant the hanger could be encouraged back in to line. A subsequent gear service meant that all gears were back where they were supposed to be.

Assorted Gear Hangers

Time for a wee catch-up. First off, it’s all been about gear hangers these past few weeks. You know, those small pieces of alloy that form a bridge between your frame and the bike’s rear derailleur. Important things gear hangers. If your rear mech takes a whack, the gear hanger’s designed to bend (up to a point) thus protecting the frame and hopefully minimising damage to your derailleur. This lot all had that in common (unfortunately, the Specialized Bicycles Pitch needed a new hanger as well). I’ve included a couple of pictures of the Focus Bikes Izalco Pro’s rear derailleur which appeared to have overshot its’ low stop and ended up in a right pickle. Easing the low stop off saw the spring compress (nearly taking my hand off) and it once again resembled a rear mech (phew!)

Trek XCaliber

Next up a Trek Bicycle Xcaliber which had parted company with its rear derailleur. A new KMC Chain USA 10spd chain along with the correct size cage Shimano MTB SLX rear derailleur and the obligatory BETD Goldtec gear hanger and it was ready for more shredding.

Pinnacle Ramin

Next up we have a mighty, mighty Pinnacle Ramin. This is one burly bike with full Shimano MTB XT, Shimano MTB SLX hydraulic brakes and Alexrims. New cassette, re-aligned gear hanger, new bottom bracket cups and a trued rear wheel meant it could make it out over the Easter break with accurate, smooth shifting guarantee.

Norco Valence

Seems like it’s been hanger week at Andy’s Bike Clinic. This Norco Bicycles Valence needed a replacement hanger, Shimano Cycling 105 rear derailleur and a KMC Chain USA chain. After fitment, a quick gear adjustment, and it was back putting miles under its tyres on the tarmac.

GT Aggressor

Next up, a GT Aggressor which leads a busy life. Unfortunately, its gear hanger came off worse with a sudden impact, so a new hanger and Shimano Cycling rear derailleur were fitted. Smooth shifting suitably restored, its owner can resume their commute via bike.
